Coolant-Fed Carbide-Tipped Drill Bits
 |
Extended Length Round Shank |
 |
Standard |
Channel coolant through the holes to reduce heat and evacuate chips more efficiently than other bits. These are designed for CNC machines that supply coolant through the spindle rather than an external source, such as a hose and nozzle. Coolant flows directly from the bit's tip onto the drilling surface. This speeds up cuts and leads to excellent performance in deep holes and tough materials such as stainless steel and titanium. A lower-price alternative to solid carbide, they stay sharp when drilling abrasive material but won’t last as long.
Extended Length—Drill through panels and thick workpieces with our longest bits. Their length is good for creating deep holes but makes them less rigid than other bits. As a result, they are more prone to wobbling or breaking, especially when drilling hard materials.
Carbide-Tipped Drill Bits for Masonry and Concrete
Crush rather than cut material so bits don’t jam or overheat while drilling masonry and concrete. The ultra-hard carbide tip breaks masonry into pieces and the widely spaced flutes channel them out of the hole. These bits stay sharp, resisting wear and heat that will dull or break other bits.
SDS-Plus Shank for Hammer and Rotary Drilling
 |  |
SDS-Plus Shank |
The slotted shank fits SDS-Plus-drive rotary hammers, which rotate and hammer bits simultaneously to penetrate material. Also known as percussion or impact bits.
High-Speed Steel Drill Bits for Wire Installation
 |
Feed electrical wire, data cables, and phone lines through walls with the same tool used to make the hole. Once you've drilled, insert wire through the bit's hollow shaft to the other side of the wall. These are simpler to use than flexible-shaft bits since you do not need to strip the end of the wire. Also known as bell hanger bits.
Black Oxide—The dark finish increases wear resistance and reduces friction to improve chip flow, so these bits can last 50% longer than uncoated bits.
