    I feel like I have stepped up into a “used to” category. I “used to” use my Craftsman and Makita drill bit sets. I “used to” occasionally break bits off from putting too much pressure on them to get them to cut faster. These bits are so much better than the grades you get at Sears, Lowes, Home Depot, etc. I have been upgrading my 57 chevy including drilling 1/2″ holes through the A arms to put in an anti-sway bar. Tasks are just easier when you don’t have to stop and sharpen a bit or keep drilling because you’re almost done… just a little longer and I’ll be through. You know what I mean. These bits belong in any do-it-yourselfer’s tool box. I would recommend these bits to my friends and thank my friend for recommending this brand.

    After several use drilling 3/8″ mild steel I noticed that I already have several bits with chipped ends. These bits get dull quickly too.

    Made in China.

    Would not buy again.

    I have never had any good quality bits before. All I have ever owned were the cheap $20.00 sets from walmart etc. Cobalt bits are the way to go if you are drilling any kind of metal. These bits require no effort at all to cut through steel. I would recommend this product to anyone needing to drill metal

    I have always used old High Speed Steel bits and they work ok until you have to drill into something a little harder than mild steel. These bits come in a nice case and are worth the money IMO.
