MAKITA 3 1/8-inch x 22-inch SDS-max Core Bit

Bosch Cobalt M42 Metal Drill Bits are engineered with upgraded M42 alloy, containing 8% cobalt. These hard-core cobalt bits deliver 10X life vs. standard bits, are jobber length and withstand high-heat applications. The thick web-helix design delivers fast material removal and increased stability. Bits that are 1/8 In. and larger feature a split point, bits 3/16 In. and larger feature a three-flat shank, for better bit grip. These cobalt drill bits provide superior performance in stainless steel and can be used to drill cast iron, titanium and other hard or abrasive metals.

Bosch SDS-max carbide-tipped rotary hammer core bits offer an integral shank for better power transmission. Bosch SDS-max rotary hammer core bits with wave design go beyond the range of standard bits and allow smaller hammers to drill larger holes. Wave design transfers energy to bit more effectively for up to 40 percent faster drilling versus previous design.

Bosch brings constant innovation to concrete and masonry drilling. Bosch developed custom-manufactured carbide and diffusion bonding technology to provide better performance and durability. Spline thru-hole rotary hammer bits offer less vibration and quieter operation thanks to an efficient design that maximizes the power of the hammer.

The Milwaukee 1 1/8 inch Ice Hardened Hole Saw delivers up to 50% longer life and 2X faster cutting than the competition. The Milwaukee Ice Hardened Hole Saw is made with a proprietary cryogenic process that consistently hardens to the core. The result is performance thats superior to traditional heat treat processing.
