4B2 dish grinding wheels 125x6x2x10x20x32 P B2-01 100% ACH M 16

4B2 Diamond Grinding Wheel – Dish Type | FEPA M16 (14/10 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:

Used for face grinding and sharpening of cutting tools at pre-finishing stage.
Typical applications include:

• Face grinding of end mills and milling cutters
• Sharpening of carbide saw blades
• Preparation of reamers before final finishing

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

What it actually does:

Fine grinding and surface preparation before final finishing.
Controlled material removal for stable geometry and consistent surface quality.

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 for sharpening.
Used after M25 / M20 and before M10.
Focus is geometry stabilization before final finishing.

Specification:

• Type: 4B2 (dish)
• 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:

• Accurate face contact
• Access to cutting edges
• Suitable for angular surfaces

Use for:

• Face grinding
• Tool sharpening
• Pre-finishing

Do not use for:

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