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 with reduced grinding forces.
Typical applications include:

• Profile grinding on machines with limited rigidity
• Initial shaping of chip breaker geometry on end mills and drills
• Operations where lower thermal load is required

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

What it actually does:

Productive material removal with smoother cutting behavior.
Less aggressive than 100% concentration, but easier to control in sensitive setups.

Grain size (D107 ≈ 100/80 μm):

• High stock removal rate
• Typical Ra ~ 0.6–1.2 μm
• Prepares surface for D91 → M63 sequence

More forgiving and less prone to loading than 100% concentration.

Concentration 75% means:

• Reduced grinding forces
• More open structure → better chip evacuation
• Smoother cutting action
• Trade-off: shorter tool life vs 100%

In practice:

This is a controlled roughing wheel.
Used when stability is more important than maximum productivity.
Ideal for long tools, thin geometries and vibration-prone setups.

Specification:

• Type: 1FF1 (double-sided conical)
• Abrasive: Synthetic diamond (AC4)
• Grit: FEPA D107 ≈ 100/80 μm (ANSI 140/170)
• Concentration: 75%
• 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
• Stable rough grinding

Do not use for:

• Maximum stock removal with high pressure
• Final finishing
• Polishing
