Cobalt High-Speed Steel Drill Bit, 29-Piece Metal Index Set. THIS LISTING IS PROTECTED BY OUR. The Irwin 29-Piece Cobalt M-35 Metal Index Drill Bit Set includes drill bit sizes measuring from 1/16 to 1/2-inch in 1/64 inch increments. The 29 bits are made using heavy duty web construction for strength and durability, and the cobalt steel extends the life of cutting edges. The 135-degree split point tips start drilling on contact and cut with less force. A reduced shank above the 3/8-inch point lets you use larger drill bit in a 3/8-inch chuck, and you can select the right bit using a convenient tap and drill selection chart. The set’s rubber overmolded case protects against damage from accidental dropping, and you can remove cartridges to easily carry bits from the case to your worksite. Ideal for drilling in tough metal, including heavy-duty abrasive alloy metal drilling on hardened steel. Made from industrial grade High-speed steel for increased durability. 8% Cobalt alloy is heat and abrasion-resistant. 135-degree split-point tip starts drilling immediately with less force and eliminates “walking” across the work surface. Metal index case for easy bit access and identification. Includes drill bit sizes 1/16- to 1/2-inch in 1/64-inch increments. I took on the project of building my new shop. I figured that when they came in if I didn’t like them I could return them. Well they came in and I was very impressed with the quality and sharpness of the bits. This is by far the BEST set of bits I have ever owned. If you compare the costs of’throw-away’ drill bits, and then figure the frustration of having busted small bits… Worked as advertised, never had one break. Worked perfectly, have never had one break, seem stronger than most bits. Using metal to metal is machining: slow, steady patience is rewarded. I use a variable speed drill, very slow, and a rig to hold it steady. These worked perfect to remove a hardened steel bolt buried half an inch into a engine block. Stuffed hole with paraffin, used torch to heat up the bolt and the surrounding metal so the paraffin wicks into the threads, repeat two or three times, bolt eased out perfect.
