Diamond Lapping Plate

What is it?

A diamond lapping plate has industrial diamond grit bonded to a flat surface, sharpening hard tool steels fast and flat. It is used to true plane soles, flatten stones, and sharpen carbide.

What is it used for?

• Sharpening carbide and hard steel
• Trueing plane soles and stones
• Fast, flat lapping

How to choose

Choose grit for the stage: coarse to reshape, fine to finish. A plate that lies flat on the bench sharpens true.

Anatomy

Understanding the parts of a diamond lapping plate helps you use, maintain, and buy it with confidence.

• Body: the main working portion of the tool
• Working end: the part that contacts the material
• Handle: the part you grip for control and leverage

Materials & construction

Quality diamond lapping plates are made from hardened, heat-treated steel (often chrome-vanadium or high-carbon) chosen for strength, edge retention, and resistance to wear and corrosion.

Safety & maintenance

• Wear safety glasses; metal chips and fragments are sharp
• Use the correct technique and pressure for the material
• Keep the tool clean and store it safely
• Fit a handle where the tool uses one to protect your hand
