1FF1 flat grinding wheels with double-sided conical profile 100x2x4x4x20 S B2-01 100% AC4 D 91

1FF1 Diamond Grinding Wheel – Double-Sided Conical Profile | FEPA D91 (80/63 μm)

1FF1 flat diamond wheel with double-sided conical profile for profile grinding of cutting tool features.
Designed for carbide and other hard brittle materials.

Where it is actually used:

Used for grinding chip-breaking flutes and narrow profiles at the rough stage of profile formation.
Typical applications include:

• Initial shaping of chip breaker geometry on end mills and drills
• Grinding of narrow flutes and grooves
• Profile preparation before transition to micron sequence

The double-sided conical profile enables stable profile generation with controlled contact.

What it actually does:

Productive material removal with basic control of geometry.
Removes bulk material and establishes initial profile shape.

Grain size (D91 ≈ 80/63 μm):

• High stock removal rate
• Typical Ra ~ 0.4–1.0 μm
• Leaves visible grinding marks

Stable and not sensitive to feed or depth.

In practice:

This is a starting wheel for profile grinding.
Used before M63 → M40 → M25 sequence.
Focus is fast geometry formation, not surface quality.

Specification:

• Type: 1FF1 (double-sided conical)
• Abrasive: Synthetic diamond (AC4)
• Grit: FEPA D91 ≈ 80/63 μm (ANSI 170/200)
• 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:

• Access to narrow grooves
• Controlled profile generation
• No interference in tight areas

Use for:

• Chip breaker flutes
• Tool profile grinding
• Initial profile shaping

Do not use for:

• Open flat surfaces
• Finishing (use M63 → M10)
• Polishing
