1FF1 flat grinding wheels with double-sided conical profile 125x4x5x8x32 P B2-01 100% AC4 D 107

1FF1 Diamond Grinding Wheel – Double-Sided Conical Profile | FEPA D107 (100/80 μm)

1FF1 flat diamond wheel with double-sided conical profile for rough 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 where high material removal is required.
Typical applications include:

• Initial shaping of chip breaker geometry on end mills and drills
• Grinding of narrow flutes and grooves from solid or semi-finished state
• Profile preparation before D91 / M63 sequence

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

What it actually does:

Aggressive material removal with basic geometry control.
Removes bulk material quickly and establishes initial profile shape.

Grain size (D107 ≈ 100/80 μm):

• High stock removal rate
• Typical Ra ~ 0.6–1.2 μm
• Leaves deep and visible grinding marks

Stable under heavy grinding conditions.

In practice:

This is a primary roughing wheel for profile grinding.
Used before D91 → M63 → M40 sequence.
Focus is productivity and fast geometry formation.

Specification:

• Type: 1FF1 (double-sided conical)
• Abrasive: Synthetic diamond (AC4)
• Grit: FEPA D107 ≈ 100/80 μm (ANSI 140/170)
• 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
• Rough profile shaping

Do not use for:

• Open flat surfaces
• Finishing (use D91 → M10)
• Polishing
