I used this bit to drill into my trucks frame to install a hitch. It did awsome and still looks like new after drilling 8 holes in really hard metal.

Rated 4.0 out of 5.0 by Rip Worked very well. Stayed sharp after drilling many holes through 3/16" steel

Rated 5.0 out of 5.0 by jrb Impressive drill bit
This is a fast cutting, aggressive drill bit. Yet while being aggressive, it actually takes small bites, resulting in quick yet smooth drilling, with little “catching” or binding. It also appears to be very durable, I have drilled a dozen holds in ¼ inch steel, and the bits shows no sign of dulling. I like the 3 flats cut on the shank, preventing the bit from slipping in the chuck, which can be a problem with larger bits and more powerful drills. While cobalt bits are considerably more expensive than HSS, their longer life and ability to drill harder materials outweighs the additional cost.

Rated 1.0 out of 5.0 by Bob Got dull very fast compared to other cobalt drill brands.
I attempted to drill through a loose car wheel stud using this drill bit and it got dull after about 1/4".
My car had two loose spinning wheel studs and I used a Bosch brand bit and Irwin brand bit to drill one all the way off and the second stud about half way off before they got dull. Those bits were also cheaper than this bit.

I was able to drill about 1/4" into cast iron with the bit before the ends rounded over. I bought a dewalt bit & drilled 7 holes with no problem. Don't waste your money.

Rated 3.0 out of 5.0 by cm1101 Decent quality
I thought this was a premium drill bit- as with other brands, they all are sub par quality in professional applications - the bits that harbor freight sells are just as good IF not better and normally sell for a 1/4 of the price... Disappointed. Again... HD should carry a "higher" line or lower their prices.

We purchased these bits because we were replacing a deck on our 35' flatbed. We broke 6 DeWalt bits and the young man at Home Depot recommended this bit. We finished over 1/2 of the deck on one bit! Great performance!

Used to drill out exhaust manifold studs that broke off and it went dull a lot quicker than it should of. Was junk after the job was done.
