These are high quality, super tough, jobber length cobalt drill bits. Cobalts have a thicker web and last much much longer. Should be ran at low to medium speed. Great for using in a hand drill or drill press for drilling out rivet bodies rivet heads on conversions. 3/32" and 1/8" should be used to drill through rivet bodies and 3/16" and larger are great for removing the old FCG axis pin heads and rivet heads when doing pistol grip conversions. #36 is used to predrill holes for #6-32 threading, #29 is used to predrill holes for #8-32 threading, #21 is used to predrill holes for #10-32 threading and can be used for 4mm index pin holes in front sight blocks. The 3mm (0.118") drill bits are used for drilling holes to install front sight block and gas block cross-barrel pins.
