1A1 straight grinding wheels 200x5x40x32 P B2-01 100% ACH M 10

1A1 Diamond Grinding Wheel – FEPA M10 (10/7 μm) | B2-01 Bond

Straight diamond wheel (1A1) for precision finishing, not rough grinding.
Designed for carbide, ceramics and other hard brittle materials.

What it actually does:

Ultra-fine finishing and edge refinement. Very low stock removal, high surface quality.
Works clean, almost no burning, but does not forgive aggressive feed.

Grain size (M10 ≈ 10/7 μm):

This is micron powder, not a standard grit.

• Used for final finish and polishing
• Can reach very low Ra ~ 0.02 μm with proper setup
• Practically no stock removal — only refinement

Requires stable machine and good coolant.

Bond (B2-01):

• Self-sharpening
• Low heat generation
• Clean cutting edge
• Wears faster than metal bond, but gives better surface

In practice:

This is a last-step wheel.
If you didn’t prepare the surface before — it won’t fix it, only polish what’s already there.
Works best after D46 → D16 sequence.

Specification:

• Type: 1A1 (straight)
• Abrasive: Synthetic diamond (АСН)
• Grit: FEPA M10 ≈ 10/7 μm (ANSI 2000)
• Bond: B2-01 (resin-based)
• Concentration: 100%
• Body: P (pressed composite)
  (Aluminum or Steel on request)

Concentration 100%:

• More cutting points → stable finish
• Better edge retention
• Longer tool life
• Note: can load if overloaded

Body type (P):

• Lighter than steel
• Damps vibration
• Stable for finishing
• Limit: lower rigidity vs steel

Dimensions (D × X × T × H):

• D – outer diameter
• X – diamond layer
• T – total thickness
• H – bore

Use for:

• Carbide finishing
• Final sharpening
• Edge honing
• Ceramics / glass

Do not use for:

• Steel
• Heavy grinding
• Aggressive feed
