Product Description

Product Description

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 Steel 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. IRWIN Tools Cobalt Alloy Steel High-Speed Steel Drill Bit, 29-Piece Metal Index Set (3018002).

Amazon.com

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.

5 Stars
It's so nice to have something work like it supposed to.
Bought the 5 reverse bits along with Irwin E-Z outs and spring loaded center punch in the frequently bought together feature.The bits impressed me right off as I've never seen a drill bit pull ribbons of metal out of a grade 5 bolt like it was aluminum. A pilot hole and then the correct size for the e-z out. A couple taps and was able to unscrew the broken muffler bolt put of my snowblower. Took me longer to find my Kroil to soak for a couple hours than it took to get the bolt out. Nice kit that worked perfect. Great not to have to load up equipment to take to the small engine repair shop.You don't use it often, but good to know you bought a quality set-up.
