HOW TO SELECT THE
PROPER INTERNAL LAP INTERNAL LAPS should be longer
than the length of the bore being lapped.
STANDARD INTERNAL LAPS are manufactured undersize to allow for
stock removal and abrasive clearance. Order a 1/4" lap to
finish a .2500 diameter bore.
RADIAL GROOVES are recommended for most lapping applications;
however, there are instances when non-grooved laps are recommended, such
as when lapping interrupted bores.
SPECIAL SIZE AND/OR
LENGTH LAPS AND ARBORS
CAN BE MADE TO SUIT YOUR APPLICATION.
All internal laps 3/16" and
larger are shipped with radial grooves. If grooves are not
preferred, specify "no radial grooves" when ordering.
