29Pcs Cobalt Drill Bit Set, 135 Degree Tip High Speed Steel with Black and Gold Finish, Stainless Steel, Plastic and Wood with Metal Indexed Storage Case 1/16"-1/2"

I used the item as soon as I got them it’s so nice to use quality drill bits this item works great!

Great drill bits! I ordered these to drill out rivets in the floor of my 18’ aluminum boat so I could replace the foam. With no room for error I needed a quality drill bit that wouldn’t walk. These did the task perfectly and lasted for a long time. Removed whole floor with only using two bits. I could have done it with one, but toward the end the first bit started to dull slightly. I will order more of these bits in different sizes in the future.

Great value for the money, durability, quality, works well.

I bought these bits to drill into a hard steel rod that was about 1/2" in diameter. My conventional bits barely put a dent in it, and even a cobalt bit I had lying around couldn't hack it (probably since it was old and dull). I bought a ten-pack thinking I would burn up a few of them drilling the one hole, but I was pleasantly surprised that I only needed one, and it went right through the rod with no trouble at all. I did use oil to help cool and lubricate the bit, as it got very hot. I recommend these bits very highly, especially for the price.

I had never used cobalt bits before, but a recent project requiring holes in very tough hardened steel required it. My normal bits wouldn't tough the stuff. These worked flawlessly

These drills are sharp and cut excellently. Great price for a great set. As others commented: it's a bit hard to read some of the drill sizes in the "wing" holders.

I thought one set of these for my husband and he loves them. He asked me to order another set and to keep the information to order again if need be!Great service

It was missing the 1/16 drill bit
