Narwhal 5/8" Drill Bits for Metal (M35 Cobalt - 3 Pack) 6 Inch Length & 135 Degree Split Point for Drilling Into Metal, Hardened & Stainless Steel, Cast Iron, & More!

The drill bits are hard to beat. For the price, they drill well, keep their edge, and when dull, they can sharpen multiple times. Even if other bits of higher quality were sought, chances are you will break the bit before you get the life out of it. These, I can easily purchase again and again for a small fraction of the cost. I've had no issues with them at all. The length is great. True to size. Straight. packaged well. Great value. Durable, and they cut metal. That is what is most important to me. I love it and all the varying sizes.

These bits are working great for me...still using first one and have poked at least 70 holes in thinner stainless in a shipping container. I just poked another 10 holes today and quick easy mounting wire hold downs to dress up the runs. First one not broke and still sharp...not as easy as first hole but still respectable and prob by 100 holes will get to my bit sharpener to prolong the life of the bit and not break by pushing too hard. Great value in my opinion for my needs!

Bought these for a job and I will be buying more! Cuts down on the time I spend drilling with other drill bits. Good quality. Stays sharp when using cutting oil but they will get ate up if you use them hard. Nice storage case and function as designed.

So i thought they were carbide bits but they were cobalt. Doesn't really matter they did a good job of drilling and they come in a nice package so the ones I didn't use aren't floating around my toolbox all willy nilly. Good quality if im in need of another handful of a different size I would consider buying this brand again.

I have tried so many different drill bits and am glad to have found these. I was drilling through 1/8" mild steel and had to make nearly a hundred holes with this very specific size. I did start using a 2nd bit about 3/4 way through my project but even if I only had one bit I would have been fine. A definite winner! Sharp fast and durable.

I had several holes to drill so I bought the 3 pack. They worked so well just one bit lasted the entire project and it’s still sharp. Also they didn’t walk when drilling stayed right on the mark

Great bits had no issues drilling thrugh metal

Very sharp and sturdy cuts through metal like butter very good quality

Awesome bits! Got these to repair some exhaust manifold stud holes and they go through aluminum like butter.

Exelente producto ya lo he probado y no hay queja, llego en tiempo y forma. ¡BIEN POR USTEDES!

A bit of a wait, but worth it, and the price was good. Used one almost all day drilling holes in steel panels, works good, cuts nice and still as sharp as when I started.

Nice to get a unique size. So far, does the job perfectly!

Good stuff Thanks
