Tool Bit Height Gage
Aluminum height gage used to quickly set tool bit height using a QCTP.
Right side for standard settings & left side for upside-down, backside bits.
Facing cuts were made on a collet-held piece until no center nub remained.
That height then operationally defined the tool bit height for the gage.
A Dorian Tool, negative rake TNMG carbide insert tool bit holder MTGNR is shown.Tool bit should be at or slightly below center for turning &
at or slightly above center for boring. The gage rests on the cross slide.
