Champion Cutting Tool RotoBrute High Performance CT150-1-1/8 Carbide Tipped Annular Cutter (1-1/8 inch diameter x 1-3/8 inch depth of cut)

I got the 3/4 x 1 3/8 cutter. I was trying to drill 1/2 in plate that had the holes plasma cut, the wrong size. Well let me tell you after trying 6 different cutters and various drill bits, this one WORKS! Most of them cut about 6 holes then were done, this one just kept cutting. I was punching 0.70 holes out to 0.75, with a total of 216 holes. After 168 holes, over a 3 week period and lots of cutting oil, it finally quit. No shame in that what so ever, especially when some of them only drilled 3 holes. Ordering another.

This is a top of the line cutter. Works perfect and makes a nice looking hole.
