Manufactured by UKAM Industrial are Multi Layered. They have 3 layers of diamonds, not just 1 layer of diamonds like conventional electroplated drills. This provides longer drilling life, faster and freer drilling action, & more consistent performance. Unlike cheap imitations, diamond will not peel or pull out

  • High Diamond Concentration

  • Smooth Surface Finish Quality

  • Fast Drilling & Consistent Performance

  • Superior Quality & Consistency

  • Maximum Diamond Particle (Grit) Exposure

  • Preserves True Material Micro Structure

  • Long Life when used correctly

  • Superior Design that is Easier to Use (Easier Core Removal)


Electroplated  Diamond Core  Drills & Electroplated Thin Wall Diamond Core Drills produced by UKAM Industrial are MULTI-LAYERED they have several layers of diamonds, held by a tough durable nickel alloy. Providing igh  diamond  concentration and maximum diamond particle (grit) exposure/protrusion ratio. This provides freer,  faster drilling  action  with  minimum heat generation.

Electroplated Diamond Drills provide excellent performance on softer materials ranging from 6 to 1 on mohs scale of hardness. While electroplated diamond drills, specifically manufactured by UKAM Industrial, will still work on  harder materials (up to 9 on mohs scale).

Diamond drill life will be (very short) significantly reduced. Diamonds stay on the surface of the drill allowing for fast material removal. Perfect for softer, more ductile, and gummable materials.  Not recommended for drilling very abrasive materials such as sandstone and concrete (they will wear out on these materials almost immediately). Electroplated Diamond Drills last less than metal bond, and are least expensive diamond drills available. They provide very smooth surface finish quality & less thermal damage to the part being drilled.

Electroplated (nickel bond) diamond products usually have a single layer of diamonds, held by a tough durable nickel alloy. Nickel is frequently used as a base for plating diamond. Because of its excellent strength, toughness and flexibility during the plating process. Electroplated diamond products are able to retain their original shape and dimensions thought their working life. Unlike sintered (meal bond) or resin bond diamond products, where diamond particles are buried in bond and held together by metal or resin binder deep inside. Electroplating allows diamond particles to protrude from the bond matrix, providing a free, faster cutting action with minimum heat generation. 

Most Electroplated diamond drills/bits have only one (single) layer of diamond coated on a steel body. Diamonds stay only on the surface. When this diamond portion is worn out or peeled off, the diamond drill will slow down, drill on the side (not drill straight) or stop working (drilling) altogether. Not all electroplated diamond drills 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.

Only the highest quality synthetic or natural 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.  Our experience, precision manufacturing, modern quality control methods, allow us to control and regulate dozens of variables that affect diamond drill life, quality of cut, surface finish. For Best Results: Diamond drills must be used with a continuous flow of water. Drilling should be carried out in a water bath. Use submerged-pressure sensitive feed.  


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. As well as home owners and contractors requiring to drill a few holes when installing tile, marble, shower doors, glass mirrors, 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" (6.35") into material. Performance/Life in many harder materials (granite as an example) will decline when drilling thicker materials.
