1FF1 Diamond Grinding Wheel – Double-Sided Conical Profile | FEPA D151 (150/125 μm)

1FF1 flat diamond wheel with double-sided conical profile for heavy rough 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 at early machining stages.
Typical applications include:

• Initial shaping of chip breaker geometry on end mills and drills
• Grinding of deep and narrow flutes with lower machine load
• Operations requiring better control in unstable setups

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

What it actually does:

High material removal with smoother and more controlled cutting behavior.
Less aggressive than 100% concentration, improving stability and reducing vibration impact.

Grain size (D151 ≈ 150/125 μm):

• Very high stock removal rate
• Typical Ra ~ 1.0–2.0 μm
• Prepares surface for D126 → D107 sequence

More forgiving and easier to control than 100% concentration.

Concentration 75% means:

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

In practice:

This is a controlled heavy roughing wheel.
Used when process stability is more important than maximum removal rate.
Ideal for vibration-prone setups and long or thin tools.

Specification:

• Type: 1FF1 (double-sided conical)
• Abrasive: Synthetic diamond (AC4)
• Grit: FEPA D151 ≈ 150/125 μm (ANSI 100/120)
• 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
• Controlled heavy rough shaping

Do not use for:

• Maximum stock removal with high pressure
• Finishing operations
• Polishing
