The Dude's Cobalt Drill Bits

The Dude’s M42 Cobalt Drill Bits stand the test of time. Constructed of a patented 8% cobalt and high-molybdenum alloy, The Dude’s Cobalt Drills cut the hardest stainless steel, Inconel, and AR400. The Dude’s cobalt drill bits are constructed with a wider web design which increases the drill bit strength, and allows for faster chip removal resulting in a “cooler” bit. The Dude’s Cobalt Drill bits feature a 135 degree split point which prevents “drill walking.” Shanks on sizes 3/16” and greater have 3, machine-ground flats, which prevent slippage in drill chucks. The Dude’s Cobalt bits are available in a wide assortment of jobber sets: Our 13 piece set runs from 1/16” thru 1/4” by 64ths, our 15 piece set runs from 1/6” thru 1/2” by 32nds, and our most popular 29 piece set runs from 1/16” thru 1/2” by 64ths; we also have added in a 21 piece set that runs from 1/16” thru 1/4” by the 64ths and 9/32” thru 1/2” by the 32nds. The Dude’s M42 Cobalt bits are also available in number sets from #1 thru #60, #61 thru #80, and letter sets from “A” thru “Z” as well has our 115 piece master mechanic’s set that includes fractional sizes from 1/16” thru 1/4” by 64ths, number sizes from #1 thru #60, and letter sizes from “A” thru “Z”. The Dude also offers the same sets in Machine Screw “Stubby” sizes.
