1FF1 Diamond Grinding Wheel – Double-Sided Conical Profile | FEPA M25 (28/20 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 where material removal and geometry formation are required.
Typical applications include:
- Rough shaping of chip breaker geometry on end mills and drills
- Grinding of narrow flutes and grooves
- Profile preparation before M20 / M16 finishing stages
The double-sided conical profile enables stable profile generation with controlled contact.
What it actually does:
Productive material removal with initial surface refinement.
Establishes profile geometry and removes marks from previous rough grinding stages.
Grain size (M25 ≈ 28/20 μm):
- Higher stock removal than finer micron grits
- Typical Ra ~ 0.15–0.30 μm
- Prepares surface for M20 → M16 → M10 sequence
More stable and less sensitive than finer finishing wheels.
In practice:
This is the entry step for profile finishing sequence.
Used after rough grinding (D46 / D64) and before M20.
Focus is productivity with controlled geometry formation.
Specification:
- Type: 1FF1 (double-sided conical)
- Abrasive: Synthetic diamond (АСН)
- Grit: FEPA M25 ≈ 28/20 μm (ANSI ~600–800)
- 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 finishing
Do not use for:
- Open flat surfaces
- Final finishing (use M16 / M10)
- Very fine polishing
