Review on CMT 857 503 11 Chamfer 1 Inch Diameter by Radney Taala

I am building reverse doors with raised panels and wanted to make a slight bevel on the back of my panels. I first separate the back of the panel with a folded groove set and then finish with that. I had to remove the bearing and grind the tip of the bit with a cutting wheel, but it didn't last long. I am satisfied with the quality of the CMT carbide drills and find that their drills are always well made.
