1FF1 Diamond Grinding Wheel – Double-Sided Conical Profile | FEPA D213 (212/180 μm)

1FF1 flat diamond wheel with double-sided conical profile for extreme 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 the earliest machining stage.
Typical applications include:

• Initial shaping of chip breaker geometry on end mills and drills
• Grinding of deep and narrow flutes from solid carbide
• Bulk material removal in low-rigidity or vibration-prone setups

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

What it actually does:

Maximum material removal with smoother and more controlled cutting action.
Less aggressive than 100% concentration, improving stability in difficult conditions.

Grain size (D213 ≈ 212/180 μm):

• Extreme stock removal rate
• Typical Ra ~ 2.0–4.0 μm
• Prepares surface for D181 → D151 sequence

More forgiving and less sensitive to machine instability.

Concentration 75% means:

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

In practice:

This is a controlled extreme roughing wheel.
Used when maximum material removal is required but machine rigidity is limited.
Ideal for deep flutes, long tools and unstable setups.

Specification:

• Type: 1FF1 (double-sided conical)
• Abrasive: Synthetic diamond (AC4)
• Grit: FEPA D213 ≈ 212/180 μm (ANSI 70/80)
• 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 extreme rough shaping

Do not use for:

• Maximum pressure grinding
• Finishing operations
• Precision work
