1A1 straight grinding wheels 100x5x20x20 P B2-01 100% ACH M 16

1A1 Diamond Grinding Wheel – FEPA M16 (14/10 μm) | B2-01 Bond

Straight diamond wheel (1A1) for fine finishing and pre-polishing.
Designed for carbide, ceramics and other hard brittle materials.

What it actually does:

Fine finishing with slight stock removal and good surface quality.
More aggressive than M10, but still focused on finish, not roughing.

Grain size (M16 ≈ 14/10 μm):

Fine micron powder between semi-finish and finish.

• Removes small amount of material while improving surface
• Typical Ra ~ 0.04–0.10 μm
• Good balance between cutting ability and finish

More forgiving than M10, but still requires stable setup.

Bond (B2-01):

• Self-sharpening
• Low heat generation
• Clean, controlled cutting
• Optimized for fine and finish grinding

In practice:

This is a transition wheel between semi-finish and final finish.
Often used before M10 or as a final step when ultra-low Ra is not required.
Works best after D46 → D25 sequence.
