1FF1 flat grinding wheels with double-sided conical profile 125x2x4x4x32 S B2-01 100% AC4 D 151

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 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 from solid material
• Bulk material removal before D126 / D107 sequence

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

What it actually does:

Maximum material removal with minimal control of surface quality.
Quickly removes bulk material and defines the primary profile shape.

Grain size (D151 ≈ 150/125 μm):

• Maximum stock removal rate
• Typical Ra ~ 1.0–2.0 μm
• Leaves deep and aggressive grinding marks

Stable under heavy grinding conditions and high load.

In practice:

This is a primary roughing wheel.
Used as one of the first steps before D126 → D107 → D91 sequence.
Focus is speed and bulk material removal.

Specification:

• Type: 1FF1 (double-sided conical)
• Abrasive: Synthetic diamond (AC4)
• Grit: FEPA D151 ≈ 150/125 μm (ANSI 100/120)
• 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
• Heavy rough shaping

Do not use for:

• Open flat surfaces
• Finishing (use D126 → M10)
• Polishing
