Rated 4.0 out of 5 by 5 reviewers.
Rated 4.0 out of 5.0 by Better than other drill bits at HD I was hesitant to use these black oxide bits because of the cheaper price versus other drill bits. I use this bit specifically for drilling metal. The bit still is sharp enough to keep drilling more holes. Expensive titanium bits I've used go dull fast, but this material is strong enough to hold up to metal drilling. If as (super speed) metal drilling bits are not available these work well enough in a pinch... Just remember to drill slowly and use drilling lube and these will work great! December 18, 2013
Rated 5.0 out of 5.0 by It got the job done I got this bit because I have metal studs in my home. It worked perfectly to bore a hole in the studs so I could hang my 40 inch TV my Son purchased for a Christmas gift. January 28, 2014
Rated 1.0 out of 5.0 by cheap drill bit I got one hole out of this drill bit. It literally bent like a noodle on the second hole I drilled with it. September 16, 2014
