VALYRIANTOOL 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"

Worked perfectly for what I needed it for! Definitely recommend!

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.

Good for tight spaces when used with a right angle drill attachment. Particularly useful was the detailed size info in the description, so I knew it would just fit for my initial need. No problem drilling automotive sheet metal. The case is just a simple box in which the bits are loose.

DRILLED HARD STEEL WHERE OTHERS FAIL!!

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

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

Cobalt works to drill out metal. That's it. Cobalt. This works as designed. Absolutely required to drill out metal bolts on automotive

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