6A2 flat recessed grinding wheels 50x3x3x10x16 A B2-01 100% ACH M 16

6A2 Diamond Grinding Wheel – Flat Recessed Type | FEPA M16 (14/10 μm)

6A2 flat recessed diamond grinding wheel for precision sharpening and preparation of flat surfaces.
Designed for carbide inserts, cutting tools and technical glass.

Where it is actually used:

Used for precision sharpening of flat surfaces and inserts at pre-finishing stage.
Typical applications include:

• Sharpening of carbide inserts and indexable tools
• Preparation of cutting edges before final finishing
• Grinding of technical glass and brittle materials

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

What it actually does:

Fine grinding with controlled material removal.
Stabilizes geometry and prepares surface for final finishing.

Grain size (M16 ≈ 14/10 μm):

• Fine finish with slight stock removal
• Typical Ra ~ 0.04–0.10 μm
• Prepares surface for M10 finishing

In practice:

This is a pre-finish wheel.
Used after M25 / M20 and before M10.
Focus is geometry stabilization before final finishing.

Specification:

• Type: 6A2 (flat recessed)
• Abrasive: Synthetic diamond (АСН)
• Grit: FEPA M16 ≈ 14/10 μm (ANSI ~1200–1500)
• 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
• Pre-finishing

Do not use for:

• Heavy stock removal
• Final polishing (use M10)
• Steel
