CUTTING TOOL WITH CHISEL EDGE
摘要:
A twist drill has double margins and a chisel edge angle of between 80 degrees and 100 degrees to maximize hole straightness and to minimize 'walking' of the drill upon a workpiece. The drill may be modular having a removable tip body or the drill may be of a solid configuration. A tip body is consumable and may be removed and replaced as required.
