GRS 002-412 Cast Iron 6 Inch Lap

The GRS 002-412 Cast Iron 6 Inch Lap delivers an exceptionally fine, long-lasting finish on gravers and small tools—especially carbide. Precision-ground from a specific grade of cast iron, this lap offers polishing advantages that complement even modern abrasive media. Both faces are identically prepared, effectively giving you the service life of two laps in one unit.

Features

• 6 in (152 mm) diameter, precision-ground cast iron for superior edge quality
• Produces noticeably sharper cutting edges for improved tool performance and longevity
• Both sides finished identically—use either face to extend service life
• Works excellently with 1 micron diamond spray for final polishing
• Recommended for carbide tools; also suitable for tool steel, HSS, and hardened carbon steels

Specifications

Notes

• Charge lightly with 1 µm diamond spray and allow the carrier to flash off before honing.
• Wipe the surface clean between compounds to prevent contamination.
• For tool steel or HSS applications prone to grooving softer laps, a ceramic lap may be preferable for heavy stock removal.
• Ideal for final honing and polishing of gravers, knives, and small cutting tools used in engraving and stone setting.
