I don't use this type of bit too often, but when I do, it's so I don't have to carry both a drill and a screwdriver. I had another set that I never liked - the hex shank was made of pot metal, which was not magnetic, so the bit would not stay in a holder. I also broke one of the hex shanks. This set of drills has a steel hex shank, and stays put in my magnetic tool holders. The bits are sharp and seem to do the job nicely.

These are great drill bits. I had an older set of bits but they just weren't getting the job done anymore. I needed something more durable. I looked at various brands before buying these. Love the hex shank and the fact that they deliver when doing high speed drilling. Ver satisfied and would buy again from this seller.

I actually bought this set just for a sort of bits that I needed. When I received these drill bits I used the kind of bits that I needed and liked it so much I got rid of the other drill bits. I will be using these drill bits from now on. I will suggest these to anyone who does home improvements or works with drill bits for a living.

These are durable, well worth the money. I'm really pleased with them.

I have used these to drill through wood and aluminum and they remain sharp, a good range of sizes and they work in the impact gun, what's not to like...

arrived fast and are working well!

I received these quickly in a couple days and they are GREAT!!!! Even better is the COMOWARE customer service. I had a minor issue which they resolved immediately. The bits are sturdy and cut through wood, metal and laminate. The shank has a hexed end so no need to over tighten the drill collar. Overall, this is an excellent set of drill bits. I highly recommend them.

So far, they are great. Nice selection of sizes. I wish the drill holder had some way to hang it on a peg board.

the ends to form hex are good quality and slide in and lock right. They are sharp and for the price you sure can' beat them
