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

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.

Review: Nice bits. - I previously cheaped out and bought an apparently popular brand on desertcart, but I'm now convinced they were popular because of price only. Unlike those bits these Irwin bits did the job and are still sharp. I had to drill a bunch of holes in stainless steel and they went through like butter, using cutting oil and letting the bit do the work of course without too much pressure as it should be.
Review: Not junk, high quality - Spend the money they are worth it. Bought to drill stainless steel. It is best to start with a much smaller bit than necessary and work your way up to the hole size you need. These are def heavy duty.

### ⭐⭐⭐⭐⭐ Professional Mechanic approved
*by D***A on June 10, 2024*

This was my first set of higher quality drill bits & they have worked amazingly well so far. After years of cheap sets that go dull after 1-2 uses these have been a game changer. They stay sharp & cut into steel very well. Have used the set to drill out bolts that I would have never even attempted in the past. I'm sure there are higher quality sets out there for big money but for the price these do very very well. Highly recommend
