Miniature Diamond Drills 0.75mm to 6mm - with SMART CUT technology
ELECTROPLATED & SINTERED (METAL BONDED)
Getting the most from your Drilling operation: Drill Usage Instructions & Recommendations
First company to develop SMART CUT technology, advanced technology that redefines the standard in cutting and drilling.
Diamonds are oriented inside matrix, so that every diamond is better able to participate in drilling action. SMART CUT open bond bond design makes sure every diamond is in the right place and at the right time, working where you need it most. You get maximum use of diamond and bond. Find out more
Sintered (Metal Bonded) Drills vs. Electroplated Drills
- Multiple layers of diamond - Single layer of diamond
- Stands up well under aggressive conditions - Cannot be dressed (in most cases)
- Super smooth finish - Least Expensive
- Longest lasting Drill - Shortest Drill Life
be used on some materials
- Most cost effective
RECOMMENDED APPLICATIONS FOR SINTERED (METAL BOND) DIAMOND DRILLS
Varying with application and material, an average electroplated diamond sold drill drill will last you 10 to 15 holes. Metal Bond (Sintered) Diamond Solid Drill may last as much as 120+ holes (when used properly).
Once you compare price and performance per hole, Metal Bond Diamond Solid Drills are an excellent alternative. Specially when drilling ultra hard materials. Although they will cost you more than electroplated diamond drills, metal bonded diamond solid drills will more than pay for themselves in terms of life, and consistent performance.
Metal bonded diamond core drills have diamonds sintered and 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. 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, 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 mohs scale of hardness). As a general rule of thumb, Metal Bond (sintered) diamond drills last longer than other diamond drills available.
They can be used in almost all diamond drilling application ranging from very soft & abrasive materials to ultra hard materials. Typical applications include in order from hardness: Composites, Glass, Concrete, Sandstone/flagstone, Natural Stone, Optical Materials, Precious & Semiprecious stone, Advanced/Technical Ceramics, Advanced Materials, & Many Others. Sintered (metal bonded) diamond drills/bits are used & preferred in most Industrial/Manufacturing, R & D, Professional Contractor, & Serious Hobby Enthusiast / Craftsmen users. Sintered (metal bond) diamond core drills/bits are most widely used diamond drills across almost all industries & applications. They wear evenly, and are known for their long life & consistency. Precision & Accurate tolerances can only be obtained with sintered (metal bond) diamond drills.
For Best Results: Diamond drills must be used with a continuous flow of water or other type of coolant. Drilling should be carried out in a water bath. Use submerged-pressure sensitive feed.

RECOMMENDED APPLICATIONS FOR ELECTROPLATED DIAMOND DRILLS
Electroplated diamond drills are frequently used in glass and composite industries (as well as some photonics / optics) applications. Electroplated Diamond Drills are designed for small & occasional use. They are widely used by beginning diamond drill users (novices) in numerous hobby/craft applications. Such as drilling beads, clock faces, and etc. (not recommended for professional or serious industrial use).
They are also usually more forgiving to operator/user drilling mistakes than most other types of diamond drills/bits. Electroplated core drills are just about the only type of diamond drill that may be used dry (without coolant) in a few applications if needed. Best performance and results will be achieved when drilling less than 1/4" (6.35mm) into material. Performance/Life in many harder materials (granite as an example) will decline when drilling thicker materials.
Diamond Solid Thin Drills SMART CUT technology vs. Conventional Diamond Solid Drills
Not all electroplated diamond solid are created equal. Contrary to popular belief, diamond drills are not a commodity. Large differences in drill life and overall performance exist from manufacturer to manufacturer. If the diamonds fall into you hole after drilling just a few holes. The inexpensive diamond drill is no longer a bargain, no matter how much you paid for it. Find out more..
Comparing & Evaluating Diamond Solid Drills 0.75mm to 2.5mm
The performance of a diamond drill/bit for just about any application / material can be evaluated under various criteria. The importance of any criteria depends on your requirements. Diamond Drill Life - The life of a diamond drill/bit is determined by the number of holes or it can drill (parts machined). It is fairly difficult to estimate the life of diamond drill. Diamond drill life is affected by various factors such as the application, bond type, drill manufacturer, and experience of user in properly using the drill. Diamond drill life will be discussed in further detail in this guide below. The following considerations play a major role in diamond drill life:
Material Holding Method
operator experience (Understanding Proper Diamond Drill Usage Principals and Adjusting them as need to better fit their particular application & objectives)
overall age and condition of drilling equipment (precision, accuracy, & repeatability of drilling equipment used)
quality, hardness, sharpness, and mesh size of the diamonds
hardness of the bond compared to the material being drilled
experience and technology of manufacturer in keeping diamonds in the bond
