5PCS M35 Cobalt Stubby Drill Bit Set for Stainless Steel & Hard Metals & Cast Iron, with 1/4" Hex Shank for Quick Chucks & Impact Drivers, 3/32", 1/8", 3/16", 1/4", 5/16"

Great quality. Compact, and perfect for installing R/O drains.

Bought these because I had to repair the spare tire carrier on my Jeep. The area I needed to drill was very tight and I needed to use a Right-angle drill with a short bit. These drill bits worked great I was able to get in and drill the hole needed to repair the carrier. I would recommend these to anyone who needed short drill bits.

Used for drilling through a car frame. No issues with the bits.

Excelent helping tool

Will not drill hardened steel. Regular bit did just as well - very disappointing

This saved me in a very specific scenario and worked flawlessly.

Fantastic M35 cobalt for bits that stay sharper, longer. Enabling these to even drill through tough stainless steel. And their stubby advantage is not just for fitting into tighter spots, but for their ability to withstand those undesirable drilling scenarios where bit-breakage is an elevated risk.The other day I used the 1/8” bit with my impact driver, at the end of an 6” extension and angled adapter to drill through a bit of aluminum in a difficult to reach location. It was an awkward setup, but much more tolerable than with a regular length bit. I'm glad I had this stubby bit on hand.I suspect I'll get a lot of use from these stubby bits. I really only use cobalt bits for drilling metal – where full length bits are seldom necessary in a handheld drill and often liable to snap.

This bit barely made a dent in 1/8" aluminum after trying for a good 20-30 seconds.. never again
