12001 Rotabroach Magnetic Drill Annular Cutter Kit 12,000 Series 1-Inch D.O.C.

I have used these know for almost a year. Bits hold up and last compared to others would recommend them

Hougen bits are by far the best and most durable in construction. Anything else would be a downgrade.

I got the job done in a matter of minutes, these bits chew right thru that hardened steel! I can't wait to drill some more

Bought for milwaukee mag drill the 13/16 bit has cut through 50 plus holes with no issues still sharp.

Drilled steel like going through better! A must have if you have a mag drill.

My husband loves this gift.

These cutters are not the correct ones to match up with the Hougen HMD150 drill. They were suggested as being bought at the same time, but they do not fit. Need the Rotaloc Plus cutters. Kept one set (I can use in other existing drills) and returned the other set. So, I can't say directly how these tools are made or used, since they were not the cutters I expected or needed with new Drill. I should have perhaps researched the whole compatibility issue deeper and not assumed that Amazon's suggestions were correct.

just opened kit and could not used pilot center points were missing
