When specified, Riverhawk Lapping Tools are cross matched with the corresponding ring and plug gage set for a guaranteed minimum of 90% taper contact. Used in conjunction with lapping compound, lapping tools provide a method of correcting an out-of-tolerence taper to the existing shaft and hub surfaces.

The lapping tools are sacrifical and made wear at a faster rate than the hardened surfaces that are being lapped. If utilized extensively, re-dressing of the taper may be required.
