Why Sintered (Metal Bond) Diamond Lapidary Blades With SMART CUT® technology Offer The Best Value & Performance For Your Money?


Sintered (Metal bonded) diamond blades are “impregnated” with diamonds. Diamonds sintered and multiple (hundreds) layers of diamonds impregnated inside the metal matrix. Electroplated and other types of diamond blades for lapidary application have only one layer of diamond that stays on the surface. Diamonds in a sintered (metal bond) diamond blade are furnaces sintered in a matrix made of iron, cobalt, nickel, bronze, copper, tungsten, alloys of these powders or other metals in various combinations. The compacted materials are then hot pressed or sintered to full density. Heating rate, applied pressure, sintering temperature and holding time, are all controlled according to the matrix composition. 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, agate, emerald, ruby, opal, petrified wood, glass, 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 cutting hard materials from 45 to 75 on Rockwell Scale (5 to 9.5 on mohs scale of hardness). It is more wear resistant and holds diamond well in place, usually producing the highest yield/cutting & best price per cut ratio.

They will last longer & cut faster than ordinary notched, plated, and other sintered (metal bond) lapidary blades.

They wear evenly, and are known for their long life & consistency. Sintered (metal bonded) diamond blades are the latest technology available in Diamond Blades. And represent the BEST VALUE & PERFORMANCE PER CUT.

They will last longer & cut faster than ordinary notched, plated, and other sintered (metal bond) lapidary blades.

Compare SMART CUT® Series 301M SINTERED (Metal bond) DIAMOND LAPIDARY BLADES To Other Bond Types

Sintered (Metal Bonded) Lapidary Blades

(electroplated, notched, hot or colled rolled blades), Diamond Bond Type Lapidary Blades

Sintered (metal bonded) lapidary blades are the best investment you can make!  Although they may cost more than electroplated (nickel bond), hot or colled rolled or some notched lapidary blades, sintered (metal bond) blades will more than pay for themselves in terms of:

Longer Life

Other Bond type blades may cost less, and at first glance may seem like the most cost effective alternative. However, they will cost you more in the long run. Depending on material and application, sintered (metal bonded) blades may last as much as 50 to 100 other diamond lapidary blade types put together. You can’t get more life out of any other blade !!! Instead of constantly putting blades on and off the saw, you will save money by using one blade. This means cost per cut, sintered (metal bond) blades are the best choice

More Consistent performance & Faster Cutting Speed

Other Blade Types have only one layer of diamond coated on metal core. Diamonds sit only on the surface. When this diamond portion is peeled off, the blade will slow down, cut on the side (not cut straight) or stop working (cutting) altogether. While other blade types may provide acceptable level of performance softer lapidary materials such as topaz, turquoise, amethyst, and etc. They will immediately burn out on harder materials such as agates, petrified wood, sapphire and etc. Metal bonded blades are sintered and impregnated inside the metal matrix. Multiple (hundreds) layers of diamonds are impregnated inside the metal matrix. Unlike Blade Types, metal bond blades wear evenly, and are known for their consistency. You will get consistent cutting speed, and overall consistent performance from sintered (metal bonded) blades.

Are you using the right blade for your application?
many Clients wast valueable time & money by using incorrect blades for their application.
Learn what variables you should consider when chosing your next lapidary blade

Diamond Concentration :

Diamond Concentration is still a factor in determining the life and cutting speed of your Diamond Lapidary Blade. Higher diamond concentration is recommended and usually used for cutting softer and more abrasive types of materials. However, the trade off is slower cutting speed. Low diamond concentration is recommended and widely used for cutting harder materials

Blade Thickness :

Lapidary blade thickness typically ranges from .014” (0.35mm) to .085” (2.0mm). 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 due to the thickness of blade passing though the material. Blade thickness is important for users requiring most minimal amount of material loss cutting specially when cutting very valuable materials such as gemstones or meteorites There are large variety of factors that will contribute to optimal blade thickness for your material/application Including your desired cutting speed, feed rate, material diameter, thickness, hardness, density, and shape. As well as skill & experience of the operator. Thicker blades are more stiff and can whistand higher/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 students and beginning users.

Feed Rates :

Feed rate is amount of force applied to the blade to go through material being cut. This will typically vary depending on blade diameter, kerf thickness & material being cut. Generally, harder materials are cut at higher feed rates and speeds (such a precious and semi precious stones) and more softer and brittle materials are cut at lower loads and speeds (such as glass, quartz). The Speeds/RPM’s you are using, shape/geometry of the material, and how the specimen is being clamped/hold in place will affect the load that can be used for your application.

Blade Speeds/RPM’s :

Most lapidary blades are used between 4,000 to 1,000 RPM’s Typically harder and more denser materials such as Sapphire, are cut at higher RPM’s/speeds Where more brittle materials such as as glass are cutting at lower RPM’s. Most rim saws RPM’s are typically limited from 1,000 to 4,000 RPM’s. Slabbing saws 500 to 1000 rpm’s. And trim saws from 3,000 to 6,000 rpm’s.

Diamond Particle/Grit size :

Diamond Mesh Size plays a major role in determining your cutting speed, cut quality/surface finish, level of chipping 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 chipping and surface finish. If you are cutting fragile, more delicate materials then we have available from stock finer mesh size diamond blades. If you need to cut as fast as possible and surface finish is not a concern we also offer much coarser cutting blades for this application.

Bond Hardness :

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 generally require a softer bond. Whereas softer and more brittle materials require a harder bond.

Blade Outside Diameter :

Typically lapidary blade diameters range form 4” (100mm) to 8” (200mm) for trimming and 10” (254mm) and up are usually used for slabbing. The diameter should be selected based on material diameter and thickness being cut. Smaller diameter 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 pieces of material at higher loads and speeds than smaller blades Blade Inside Diameter - Most trim saws and tile saws has 5/8” arbor these are for blades 4” to 10” OD. Larger cutting machines such as 12” to 18” OD usually have 1” arbor. We can provide bushings to smaller arbor. We can also expand the current arbor size to anything you want same day.

Bond Type :

Metal bonding offers long life and durability, and is the best bond type to use for lapidary applications.
