Drill HogUSA 9/16" Drill Bit 9/16" Silver & Deming Bit HI-Molybdenum M7

This is a very nice bit that retains an edge. I used this to go thru a security / 90 min fire door. It plowed thru like paper. Very nice. I will definitely buy more of these bits.

Have bought many but wind up in other peoples tool box.

Nice bit, good for drilling

Drills nicely. I used tap magic and hopefully I can get long life out of this bit

Worked like a champ through tough spindle metal. Will buy from again!

Needed this size to drill holes in my truck frame for a front hitch. One bit survived drilling 4 holes, not sure if I'll ever use that size again.

Great drill bit !

Drilled through 1/2" cold rolled with no problem. As long as you use oil and don't rush will last
