External Expanding Cast Iron Laps & Lap Holders
Printer Friendly VersionExternal Lapping Tools should be shorter than the length of the part being lapped. When lapping a cylindrical part with lands, the external lap should be long enough to span as many lands as possible to prevent rolling edges. Standard external laps are manufactured slightly over size to allow for clearance and can be tightened to the appropriate diameter with the external lap holder.
SPECIAL SIZE EXTERNAL LAPS AND HOLDERS CAN BE MADE TO SUIT YOUR APPLICATION.
