4B2 Diamond Grinding Wheel – Dish Type | FEPA M10 (10/7 μm)

4B2 dish grinding wheel for precision sharpening and finishing of tool face surfaces.
Designed for carbide and other hard brittle materials.

Where it is actually used:

Primarily used for face grinding and sharpening of cutting tools.
Typical applications include:

• Face grinding of end mills and milling cutters
• Sharpening of carbide saw blades
• Finishing of reamers and similar tools

The dish shape provides accurate contact on flat and angular surfaces.

What it actually does:

Final finishing and edge refinement.
Minimal material removal for final sizing, ensuring high surface integrity and sharp edge definition.

Grain size (M10 ≈ 10/7 μm):

• Ultra-fine finishing
• Ra down to ~0.02 μm
• No stock removal — only refinement

In practice:

This is a final-step wheel for sharpening.
Used after M20 / M16.
Focus is surface quality and edge sharpness.
