Thin Wall Multi-Layered Electroplated Diamond Core Drills, 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, smoother surface finish, faster and freer  drilling action, & more consistent performance. Recommended for drilling full range of glass, quartz, optical materials, composites, soft to medium hard natural and semi-precious stone, as well as softer Advanced Materials. It is highly recommended that these diamond drills be used with water swivel adapter Model 5811, 5811S or 58MF to run high pressure of coolant through center of drill.

APPLICATION: (materials used on)

SMART CUT™ series Thin Wall Electroplated Diamond Core Drills provide the best and chip free performance on materials 4 to 7 on Mohe's Scale of Hardness. Materials such as: Glass, Quartz, Yag, Optical Materials, Marble, Onyx, Soft to Medium Hard, Natural & Semi-Precious Stone, Composites, Soft to Medium Hard Technical Ceramics & many other materials.

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.
