DeWALT DCD805N

Dewalt SDS plus masonry drill bits power through masonry, concrete and more with a carbide tip that maximizes bit life. An elongated 4-flute helix helps to increase material removal and 3 flats on the more→shank helps to prevent slippage.

Diablo's new 2-cutter Self Feed Bits are designed to strict tolerances in the heat forging manufacturing process resulting in energy efficient drilling with up to 2X life per battery charge. Diablo Se more→lf Feed Bits 2-cutter design and an aggressive low thread count feed screw deliver up to 2X more holes per charge. The replaceable feed screw features a pull out stop mechanism that prevents the screw from slipping out when the bit is removed from the material. The combined innovative engineering of Diablo Self Feed Bits makes them the ideal choice for making holes up to 2X faster in soft woods.

Milwaukee Step drill bits with jam-free performance feature a dual-flute design delivering up to 2X faster hole times, up to 4X longer life and up to 50% more holes per battery charge than the competi more→tion. Ideal for drilling large and small-diameter holes in steel and plastic. The Rapid Strike tip allows for fast, accurate starts that generate less heat, resulting in longer bit tip life. Black oxide coating also enhances durability, hole quality and bit life. For user convenience and accuracy. The #4 step drill bit has 9 hole sizes in 1/16 in. increments ranging from 1/2 in. to 1 in.. jam-free performance in high speed with most professional 18 Volt cordless drills lithium-ion battery technology…
