Its What You Cant See That Makes All The Difference

SMART CUT® technology

How SMART CUT® Bond Works?

Step 1

Sharpest And Finest Quality Diamonds

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.

Step 2

Diamonds or CBN Crystals

Diamonds or CBN Crystals are activated only at the exposed layer. As Bond Matrix layer begin to wear out, diamonds in a new Bond Matrix layer are immediately activated, substituting the already used up diamond layer. The SMART CUT Diamond Hybrid Bond makes sure every diamond is in the right place and at the right time, working where you need it most.

Step 3

Advanced Formulated Open Diamond Bond Design

This advanced formulated open diamond bond design insures minimal chipping, fast cut, constant speed of cut, minimal cutting noise, and most important of all, consistent performance.

About Sintered (Metal Bond)

Sintered (Metal Bond) 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). 

Faster Cutting Action

Diamond & CBN tools made utilizing SMART CUT® technology are much more aggressive than your conventional tools. They can cut faster, while still leaving behind a smooth finish free of material deformation.

More Consistent Performance

Diamond & CBN Wheels are produced using only the highest quality raw materials are used in manufacturing process. Utilizing world class quality control, inspection, and measurement equipment. Highly Experienced Engineers constantly monitor and control all material input & output at all stages of manufacturing process. Insuring product consistency for use in demanding & sensitive applications SMART CUT® DIAMOND & CBN wear evenly, and are known for their consistency. You will get consistent cutting speed, and overall consistent performance, with minimum amount of dressing.

Longer Life

In most cases tools manufactured utilizing SMART CUT® technology, will outlast other conventional material (sintered), resin, and nickel bonded diamond & CBN tools. SMART CUT® diamond & CBN tools are more sturdy than tools manufactured with conventional technologies. They are capable to retain their form and bond configuration all the way through the tools life.

Minimize Chipping & Improve Surface Finish​

SMART CUT Multi Layered Electroplated Diamond Drills have diamonds oriented and evenly distributed in a bond matrix. Providing faster, freer cutting action with minimum heat generation. This translates in improved surface finish and minimum chipping.

Best Performance & Value on the Market​

SMART CUT® Diamond & CBN Wheels are the best investment you can make! Although we may not always be the lowest cost solution provider. Our Diamond & CBN wheels can provide the best ROI. Designed for users that understand and appreciate quality. They will more than pay for themselves in terms of overall performance and provide best Return on Investment.

Manufactured Using The Highest Quality Raw Materials

Only the highest quality synthetic diamonds and raw materials are used in the manufacturing process. The highest quality standards and product consistency is maintained, using sophisticated inspection and measurement equipment.

Variables that Influence

Diamond Micro Drill Specification

Steel Body Composition

The steel body using is usually high speed steel ranging in hardness from 40 to 50 Rockwell scale C. Standard configuration of standard stock diamond micro tools is flat end cylinder but the angle and radius can also be customized if needed. 

Diamond / CBN Particle Sizes Used

Diamond sizes used range form 6 microns to 120 microns. Diamond grit size used is in proportion to diameter of the drill tip and can range form 3 to 70 microns.

Head Lengths

Head length made in proportion to diameter of the tool. Usually it cannot exceed 15 times the diameter of the tool.

Recommended RPM’s

diamond & CBN micro drills are used at high speeds ranging from 150,000 to 35,000 RPM’s. The smaller the diameter the tool the higher the recommended speed for optimal performance. The drills may work at lower rpm’s with significantly shorter drill life and possible drill breakage. Optimum RPM's will vary depending on desired cut quality, drill depth, material hardness, density, shape & porosity. Please consult our technical support team or engineering department to determine the best solution or your specific application.

Shank Diameter

shank size is usually 1/8” (3.2mm) or .040” (1mm) to fit most collets. The shank diameter is designed to be in proportion to diameter of the drill/tool. Very small diamond & cbn micro drills .001” to .015” will have shank diameter of .040” (1mm). Larger diameter micro drills .016” to .040” will have shank diameter of 1/8” (3.2mm). Smaller diameter micro drills/tools can be produced with 1/8” (3.2mm) shank and larger micro drills/tools can be made with .040” (1mm) shank. Other shank diameters can be made upon request.

Recommend Coolants

We recommend using with our SMART CUT water soluble coolant for optimal results. using proper coolant type at the right velocity, angle at drilling zone will improve the life & performance of your tool and help reduce drill breakage.
