1FF1 flat grinding wheels with double-sided conical profile 125x4x5x8x32 P B2-01 100% AC4 D 213

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 at the earliest stage of machining.
Typical applications include:

• Initial shaping of chip breaker geometry on end mills and drills
• Grinding of deep and narrow flutes directly from solid material
• Maximum stock removal before D181 / D151 sequence

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

What it actually does:

Maximum possible material removal with minimal control of surface quality.
Removes large volumes of material quickly and establishes the primary profile shape.

Grain size (D213 ≈ 212/180 μm):

• Extreme stock removal rate
• Typical Ra ~ 2.0–4.0 μm
• Leaves very rough surface with deep scratches

Stable under extreme grinding conditions and heavy load.

In practice:

This is a bulk removal wheel.
Used as the first step before D181 → D151 → D126 sequence.
Focus is maximum productivity, not precision.

Specification:

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

Do not use for:

• Open flat surfaces
• Any finishing operations
• Precision grinding
