1FF1 Diamond Grinding Wheel – Double-Sided Conical Profile | FEPA M40 (40/28 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 initial geometry formation is required.
Typical applications include:
- Initial shaping of chip breaker geometry on end mills and drills
- Grinding of narrow flutes and grooves after rough grinding
- Preparation for micron finishing sequence
The double-sided conical profile enables stable profile generation with controlled contact.
What it actually does:
Productive material removal with initial surface refinement.
Removes marks from D64 / D46 and prepares surface for M25 → M20 sequence.
Grain size (M40 ≈ 40/28 μm):
- Higher stock removal than finer micron grits
- Typical Ra ~ 0.20–0.40 μm
- Transition between rough grinding and finishing
More stable and less sensitive than finer finishing wheels.
In practice:
This is a transition wheel.
Used after rough grinding (D64 / D46) and before M25.
Focus is geometry preparation and process stabilization.
Specification:
- Type: 1FF1 (double-sided conical)
- Abrasive: Synthetic diamond (АСН)
- Grit: FEPA M40 ≈ 40/28 μm (ANSI ~400–500)
- 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
- Transition grinding before finishing
Do not use for:
- Open flat surfaces
- Final finishing (use M25 → M10)
- Polishing
