Drill Grinding Jig

Description: A drill grinding jig has been developed for sharpening drill bits. It assures perfect regrinding of used drill bits again and again on any bench grinder. This is ideal for cutting tip angles: 59° general purpose drilling; 88° to prevent snatching on thin materials; 68° recommended high production angle for small drills; 49° for soft materials (copper, lead, some light alloys); and 41' countersinking angle. This drill grinding jig has been developed by Sai Commercial Corporation.
