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
