3/16inches Cobalt Drill Bits - 13 Pack of M35 Cobalt Drill Bits with Storage Case - Perfect Drill Bits for Metal, Hardened & Stainless Steel, Cast Iron, and More!

Great bits , works well , drilled several holes in metal with the same bit ,, still sharp.

I’m still on the first drill bit and it’s still sharp after drilling over 150 holes in 1/8” to 3/16” steel. Nothing like nice sharp new cobalt bits!

I use these to drill holes for 3/16 pop rivets. They are great and sharp!

Worked great for drilling out a bolt.

Works good using to drill holes for knife handles

Im completely blown away by these drill bits. I used the 3/16 size to drill out some thick steel railing posts. These badboys did the whole job in ONE DRILL BIT. Seriously take it from me Ive done auto/handyman work for years- These are steady- well balanced, SHARP bits. I had weight behind them and they had no sign of flex. After 20 uses, my Makita Brushless was still spinning these like butter. I used a center punch for accuracy/ tiny amount of some 3 in 1 oil to keep the metal lubed. Best part is I still have 12 left over. These will be in my tool box for a long time. Definitely will be purchasing more from OWL in the future.

The first bit I used out of the 13 I ordered was great but the next 3 would only drill in soft wood I am very disappointed in the drill bits and since they only cost $10 I’m going to keep them instead of driving 30 miles to a ups store

These are great drill bits. They last a long time and are a fair price.
