Clover® Lapping Compounds
CLOVER LAPPING AND GRINDING COMPOUNDS are abrasive pastes for the cutting, smoothing and finishing of metal surfaces, and for the precision mating of metal parts. For over 100 years Clover Compounds have helped mechanics, tool and die makers, and machine builders create precision, silky-smooth fits in machine parts, valve seats and gear teeth.
Clover Compounds are formulated from silicon carbide abrasives. These compounds are classified by grit size; from very coarse to extremely fine. They are available in grease based formulations.
Clover Compounds supplement other metal removal techniques such as grinding, milling, boring and EDM machining. Where these techniques alone cannot achieve the required finishing, Clover Compounds are used to:
- Produce an ultra flat surface as in the lapping or
gauges, valve seats, spacers and mechanical seal faces.
- Smooth out surfaces as in the lapping of tool marks
from machine ways, bearing races and shaft surfaces.
- Achieve precise dimensions while maintaining smooth surfaces
as in finishing gauges, tools and dies.
- Achieve perfect mating of metal parts as in lapping
in of automotive and industrial valves, running-in gears, and
sharpening of shear-type cutters.
- Clean surfaces without changing the topography of the
surfaces as in cleaning mold cavities and die surfaces.
- Remove metal or material too hard to remove in other ways
as in finishing hardened tool steel or stellite valve seats.

Clover compounds are available with the following abrasive grains and in a range of grit sizes. See the chart for availability of grit by size.
The preferred abrasive for fast cutting of all but the hardest and toughest metals. It will produce a smooth flat surface but not a polished one.
The most widely used carrier for Clover abrasives. It retains its texture and lubrication properties during extended lapping and leaves a rust- preventing film on lapped surfaces.
