Review on π© High-Performance Jobber Carbide Tipped Drill Bit - Standard 50440 by Choice Maynard
000 holes with another brand of carbide burs with excellent results. but they are really cheap
bought for drilling 17/32" holes in 1/2" HR insert on our milling machine. Brand new, they just have blue chips strewn all over the place instead of swirls. The groove diameter was 0.5340 inch and the carbide groove diameter was 0.5250 inch. The unhardened grooves will cut into the walls of the hole and rub on first use. We drilled 10,000 holes with another brand of carbide burs with excellent results. cheap So i think it deserves a star?
