  • Decent quality for a good price.
Size: 3/8", 9.5mm
I use these to drill rivets in auto body panels. I have had this set for about a week, so far they are up to the task.

  • Good bang for the buck.
Size: 3/8", 9.5mm
Maybe not the most high quality but definitely cheaper than anywhere else. Used them on very unforgiving stainless steel that with chew up even the most expensive bits. They did ok

  • Excellent drill bits
Took my time and plowed through about 1.5 inches of titanium with a single bit (made a 1/8 pilot hole first of course). I've had other well know brand/big box store bits crumble under less stress. These far exceeded my expectations, and I didn't even have to use the other 4 bits! The key to titanium is slow speed, firm pressure and keep the metals cool. Titanium is a work hardening material and can easily cook/melt bits to death. I highly recommend this product. ... show more

  • Great value
Pretty damn good bits for the most part. Don't hit any nails or screws though .😊

  • Good drill bits for the price.
Size: 7/32", 5.5mm
Used drill bits to drill through sheet metal and plastic. Worked well. After completing job, I have several unused bits available.

  • alright for the price, not great against steel
Size: 1/8", 3.2mm
cheap for a pack of drills. will do just fine with wood but against steel will struggle/ not last long.

  • they seem to hold up
Size: 3/8", 9.5mm
I've used them several times on metal components and I have no complaints so far. I hate drill bits, seems like they never last and you're constantly sharpening them when you could be working on the task at hand instead. Try them out, I'm sure they'll suit your needs unless your drilling some crazy shit everyday. ... show more
