※ Make sure the cutting lip of drill is parallel with the slot of clamping
nut before grinding job started. If it is not parallel, adjust it again.
Attention: If the cutting lip is downward, must increase the scale of web
adjustment shelf. If it is upward, please decrease the scale of the web
adjustment shelf.
When the flute length of a drill becomes shorter, the web thickness of a drill

length of a drill, the higher scale of web adjustment shelf need to be
increased.
