Whether you’re in the semiconductor, ceramics, or precision optics industries, this blade is engineered to exceed your expectations, providing you with superior results in every application.
Produced with high diamond concentration of high quality and fine diamond grit size, evenly spaced diamonds and an optimized bond formulation, and radius on diamond edge to minimize chipping. This is essential for achieving clean, chip-free cuts with a superior surface finish.
The high diamond concentration ensures that the blade remains effective and durable over long periods, providing consistent cutting performance without requiring frequent re-dressing. This is especially beneficial when cutting glass, where a consistent cutting action is necessary to avoid inconsistent edges and unwanted surface imperfections. Additionally, cutting with high diamond concentration and fine grit minimizes the need for frequent blade changes, maximizing tool longevity and offering a cost-effective solution for high-volume glass cutting operations.
The fine diamond grit size helps to reduce the cutting force and distribute the cutting action more evenly, which results in less chipping and a better surface finish, reducing the force applied during cutting and minimizing the risk of chipping. The fine grits help the blade create even, controlled cuts, which is important when working with brittle materials like glass. This results in cleaner edges and improved surface finish, reducing the need for secondary finishing / post-cutting operations and ensuring a high-quality final product.
In glass cutting applications, minimizing chipping and improving the surface finish is not just important for the quality of the product but also for the overall efficiency of the process. With minimal chipping, there is less material waste, and less time is spent on secondary finishing, reducing overall labor cost and time.
For the best results, pair it with our SMART CUT® water-soluble coolant, which enhances the surface finish and reduces heat generation during cutting, ensuring a clean and consistent cut with every pass.

Sintered (metal bonded) diamond tools have multiple layers of diamonds impregnated inside the metal matrix. Diamonds are furnaces sintered in a matrix made of iron, cobalt, nickel, bronze, copper, tungsten, alloys of these powders or other metals in various combinations. Metal bonded diamond tools are “impregnated” with diamonds. This means that selected diamonds are mixed and sintered with specific metal alloys to achieve the best cutting performance possible on any materials such as sapphire, advanced ceramics, optics, glass, granite, tile and etc. The metal bond surrounding the diamonds must wear away to continuously keep re-exposing the diamonds for the diamond tool to continue cutting. Sintered (metal bonded) diamond tools are recommended for machining hard materials from 45 to 75 on rockwell scale (5 to 9.5 on mohe’s scale of hardness).
The newly exposed diamonds don’t effect diamonds already working on the material. Unlike many other diamond bonds, diamonds in a SMART CUT® Bond remains sharp and grow sharper with each cut, prolonging product life and consistent performance.

The SMART CUT® 455M Glass Blade utilizes fine diamond particles carefully selected to provide superior cutting performance, especially when working with delicate glass and ceramic materials. The diamond grit size significantly influences the cutting speed, cut quality, and the level of chipping and material microstructure damage during the cutting process.
Fine Diamond Grit Size – The SMART CUT® 455M blade is equipped with fine, evenly spaced diamonds, which ensures smooth and precise cuts with minimal chipping, particularly when cutting fragile glass materials such as Soda Lime Glass, Art Glass, Optical Glass, and Ceramic Glass. The fine grit size contributes to a high-quality surface finish and reduces the risk of damaging the material’s microstructure, making it ideal for high-precision applications where cut quality is paramount.
The trade-off with using finer diamond grit is a slower cutting speed compared to coarser grits, but this is necessary when working with delicate materials that require clean, controlled cuts. Coarse diamonds, while cutting faster, tend to increase material micro-damage and cause more chipping. The fine diamond grit used in the SMART CUT® 455M blade provides the perfect balance, offering excellent surface finishes and minimized chipping, even for the most sensitive glass and ceramic materials.
The SMART CUT® 455M Glass Blade features a metal bond, providing exceptional durability, long blade life, and consistent performance for a wide range of glass and ceramic materials.
Metal Bond – The metal bond in the SMART CUT® 455M ensures superior diamond retention, making it ideal for cutting tougher, denser materials such as Tempered Glass, Fused Silica, Quartz Glass, and Ceramic Glass. The metal bond offers enhanced stability and high cutting speeds while maintaining rigidity throughout the cutting process. This bond type is perfect for applications requiring consistent performance and long-lasting durability, especially in high-volume cutting operations or tougher glass materials.
Resin Bond – Resin bond blades are better suited for cutting hollow materials like glass tubing, irregularly shaped hollow materials, or when working with glass types requiring tight tolerances for edge chipping and surface finish. Resin bonds create less heat during cutting and are designed to minimize chipping and produce a smoother surface finish, which is especially important in precision cutting applications such as optical glass or delicate glass assemblies.
However, it is important to note that resin bond blades are more fragile than metal bond blades and are prone to breakage under higher pressures or in non-experienced hands. Because of their fragility, they are not recommended for novice users or environments where the blade may be subjected to excessive pressure or impact. Resin bond blades are ideal for specialized, high-precision tasks where superior surface finish and minimal edge chipping are critical, such as in cutting hollow glass tubes, thin-walled materials, and complex, irregular shapes.
In contrast, metal bond blades provide a more forgiving and durable solution for general glass cutting needs, offering better resilience to operator error and wear over time.
The SMART CUT® 455M Glass Blade is available in diameters ranging from 4” (100mm) to 14” (350mm), allowing you to select the ideal size based on the glass material's dimensions and thickness.
Smaller Diameter Blades (4” to 8”) – These blades are suitable for cutting smaller pieces of glass such as Soda Lime Glass, Art Glass, and Stained Glass. The smaller diameter blades are thinner, which makes them more flexible and ideal for cutting thinner glass materials. However, they are more prone to bending or warping under higher loads. Smaller blades are typically used for more detailed cuts at lower feed rates and speeds.
Larger Diameter Blades (10” to 14”) – Larger diameter blades offer enhanced rigidity and are more suited for cutting thicker glass materials or when higher feed rates and speeds are required. They provide greater stability during operation and are typically used for heavier, denser glass materials such as Tempered Glass, Fused Silica, and Quartz Glass. The added thickness in larger blades also reduces the risk of flexing, ensuring precise and efficient cuts at higher loads.
Selecting the correct outside diameter for your glass cutting application ensures optimal performance, stability, and efficiency. The SMART CUT® 455M Glass Blade provides versatile options to meet the cutting demands of both small and large glass materials.
Feed rates for resin bond diamond cut off blades in tile saws and precision cutting saws are critical to the cutting performance and quality of the final cut, and these rates must be adjusted to achieve desired objectives
For harder materials such as ceramics and metals, a faster feed rate may be necessary to efficiently cut through the material. This requires careful handling to ensure the blade does not overheat or wear prematurely. On the other hand, brittle materials like silicon, often used in precision applications, benefit from a slower feed rate to prevent chipping or cracking.
The optimal feed rate is also influenced by the speeds or RPMs at which the blade operates. Higher speeds can allow for quicker cuts but might increase the risk of damage to sensitive materials. Additionally, the geometry and size of the material, along with how securely it is held in place, are important considerations. Proper clamping of the material minimizes movement and vibration, enhancing the blade's effectiveness and the quality of the cut. Adjusting the feed rate manually requires a careful balance of these factors
The SMART CUT® 455M Glass Blade is designed with a medium bond hardness, optimized to provide excellent diamond retention while ensuring efficient cutting performance across a wide range of glass and ceramic materials. The bond matrix is formulated to balance durability with cutting speed, offering a longer blade life without sacrificing cut quality.
Medium Bond Hardness – The SMART CUT® 455M blade’s medium bond hardness ensures that diamond particles are retained at the optimal rate for consistent cutting performance. This bond hardness is ideal for cutting glass materials such as Soda Lime Glass, Stained Glass, Ceramic Glass, Optical Glass, Quartz Glass, and Fused Silica. The medium bond retains diamonds securely during the cutting process, which increases the life of the blade while maintaining a fast and smooth cutting action.
A bond matrix that is too soft could cause premature diamond release, resulting in faster wear and shorter blade life, while a bond matrix that is too hard would slow down the cutting process, requiring frequent dressing to expose fresh diamonds. The SMART CUT® 455M’s medium bond hardness strikes the perfect balance, offering efficient cutting without compromising the blade’s longevity.
The SMART CUT® 455M Glass Blade is designed to operate across a realistic RPM range for optimal performance when cutting different glass materials. The actual RPM range typically depends on the specific material being cut and the cutting machine used.
For Softer Glass Materials – Softer materials like Soda Lime Glass, Art Glass, Stained Glass, and Ceramic Glass are best cut at higher RPMs, generally in the range of 2,000 to 3,500 RPM. The higher RPMs help improve cutting speed, reduce the buildup of heat, and allow for smoother finishes, while minimizing chipping for these more fragile materials.
For Harder Glass Materials – Harder glass materials, such as Optical Glass, Fused Silica, and Quartz Glass, should be cut at lower RPMs to prevent excessive heat generation and reduce the risk of cracking. The recommended RPM range for these materials is 1,000 to 2,500 RPM. Cutting at slower speeds offers better control, ensuring precise and clean cuts while protecting the integrity of the material.
Diamond Concentration is still a factor in determining the life and cutting speed of your Diamond Sectioning/Wafering Blade. Higher diamond concentration is recommended and usually used for cutting softer and more abrasive types of materials. However, the trade off is significantly slower cutting speed. Low diamond concentration is recommended and widely used for cutting ultra hard and brittle materials.
Low Diamond Concentration - Typically low concentration wafering blades should be for cutting ultra hard and brittle materials such as ceramics and glass. In Low Concentration Wafering Blades, diamond works by fracture process. Pressure on each diamond crystal/particle is higher which provides enough stress to chip off small flakes in the cut.
High Diamond Concentration - High concentration diamond wafering blades are recommended for cutting metals, plastics and polymers. In this application, materials cut by a plowing mechanism. In this applications diamond plough through the material, work hardened strips of materials become brittle and break off. The greater number of diamond by volume, the quicker the cutting action will be. Increasing the number of diamond s also lowers the per unit force. For metals where it is possible to induce deep deformation layers, a lower per unit force is desirable to reduce the deformation during the cut.
Diamond Mesh Size plays a major role in determining your cutting speed, cut quality/surface finish, level of chipping you will obtain, and material microstructure damage you will obtain. Diamond Mesh size does have considerable effect on cutting speed. Coarse Diamonds are larger than finer diamonds and will cut faster. However, the tradeoff is increase in material micro damage. If you are cutting fragile, more delicate materials then finer mesh size diamond wafering blades are recommended.
Wafering blade thickness typically ranges from .006” to .040” (1mm). Thinner and thicker wafering blade are available, frequently from stock upon request. Kef thickness typically increases with blade diameter (in proportion to diameter of the blade). Kerf is the amount of material removed from the material/sample due to the thickness of blade passing though the material/sample. Blade thickness is important for users requiring most minimal amount of material loss during sectioning. For example if the user requires precision position of the cutting plane relative to the detail on the sample (IC circuit for example), a thinner and smaller diameter blade would be best for this application. Blades ranging from 3” to 5” (75mm to 125mm) in diameter and thickness .006” to .015” (0.2mm to 0.4mm) would be bet suited for this purpose. There are large variety of factors that will contribute to optimal blade thickness for your material/application Including your desired cutting speed, load/feed rate, material diameter, thickness, hardness, density, and shape. As well as skill & experience of the operator. Thicker wafering blades are more stiff and can whistand higher loads/feed rates. Another advantage of thicker kerf blades is they are more forgiving to operator error and abuse. Thicker kerf blade are recommended for use in environment where large number of individuals will be sharing and using same equipment. Perfect for less experienced and novice saw operators, such as in University laboratory.
Typically wafering blade diameters range form 3” (75mm) to 8” (200mm). Wafering blade diameter should be selected based on material diameter and thickness being cut. Smaller diameter wafering blades are thinner than the larger diameter blades and are more prone to bending and warping. Although large diameter blades are thicker, they are typically used for cutting larger and heavier samples at higher loads and speeds than smaller blades.
Ability of the bond matrix to hold diamonds. As the hardness of the bond is increased, its diamond retention capabilities increase as well. However the trade off is slower cutting speed. Life of the diamond blade is usually increased with hardness of its bond matrix. Bonds are designated on their scale of hardness from Soft, Medium, and Hard. There are dozens of variations and classification schemes based on bond degree of hardness or softness. Using diamond blades with optimum bond hardness for your application is important to successful precision diamond sawing operation. Bond matrix that is too soft for the material being cut will release diamond particles faster than needed, resulting in faster wear and shorter diamond blade life. On other hand bond matrix that is too hard will result in much slower cutting speeds and require constant dressing to expose the next diamond layer. As rule of thumb, harder materials such as sapphire and alumina generally require a softer bond. Whereas softer and more brittle materials require a harder bond.
Metal bonding offers long life and durability, while resin bonding creates less heat, provides better surface finish and is well suited for cutting hard, delicate or brittle materials.
Load/Feed Rate applied to wafering blades typically vary from 10-1000 grams. Generally, harder specimens are cut at higher loads and speeds (e.g. ceramics and minerals) and more brittle specimens are cut at lower loads and speeds (e.g. electronic silicon substrates). The Speeds/RPM’s you are using, shape/geometry of the specimen, and how the specimen is being clamped/hold in place will affect the load that can be used for your application.
Most wafering blades are used between 50 to 6,000 RPM’s Typically harder and more denser materials such as Silicon Carbide, are cut at higher RPM’s/speeds Where more brittle materials such as silicon wafers and gallium arsenide are cutting at lower RPM’s. Low Speed saws RPM’s are typically limited from 0 to 600 RPM’s. Where high speed saws offer much large variety of cutting speeds from 0 to 6,000 RPM’s.
