6A2 flat recessed grinding wheels 150x20x3x20x32 A B2-01 100% ACH M 10

6A2 Diamond Grinding Wheel – Flat Recessed Type | FEPA M10 (10/7 μm)

6A2 flat recessed diamond grinding wheel for precision sharpening and finishing.
Designed for carbide, cutting inserts and technical glass.

Where it is actually used:

Used for precision sharpening of flat surfaces and inserts.
Typical applications include:

• Sharpening of carbide inserts and indexable tools
• Finishing of cutting edges on small tools
• Grinding of technical glass and brittle materials

The recessed design provides clearance and stable access to flat surfaces.

What it actually does:

Final finishing and edge refinement.
Minimal material removal for final sizing, ensuring superior surface integrity and edge sharpness.

Grain size (M10 ≈ 10/7 μm):

• Ultra-fine finishing and polishing
• Ra down to ~0.02 μm
• Practically no stock removal — only refinement

In practice:

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

Specification:

• Type: 6A2 (flat recessed)
• Abrasive: Synthetic diamond (АСН)
• Grit: FEPA M10 ≈ 10/7 μm (ANSI ~2000)
• Concentration: 100%
• Body: P / A / S / Ap
  (Pressed / Aluminum / Steel / Aluplast)

Body options:

• Pressed: lighter weight, vibration damping, better surface finish
• Aluminum: lightweight with good rigidity, general-purpose solution
• Steel: maximum rigidity for heavy-duty grinding
• Aluplast: balanced weight and rigidity

Why this shape:

• Stable flat surface grinding
• Clearance for inserts and small parts
• Reduced interference during sharpening

Use for:

• Carbide inserts
• Precision tools
• Technical glass
• Final finishing

Do not use for:

• Stock removal
• Rough grinding
• Steel
