3 mm Fine Cut Cylindrical Tungsten Carbide Rotary Bits
3 mm cylindrical heads in fine cut – the precision complement to the cone line for flat, controlled work.
Design and Construction
3 mm cylindrical heads in fine cut: dense tooth pitch on a small cylinder for flat, controlled passes where a cone would concentrate too much pressure at one point.
How It Works
The fine cylinder spreads contact across its face – controlled stock removal on flat features, slots and shoulders at 30,000-50,000 RPM.
Applications
Precision flat work, slot and shoulder dressing, small-part finishing, electronics.
Field Cases
- Electronics: 3 mm cylinders squared slot edges without breakout.
- Tool room: shoulders dressed flat where a cone would gouge.
- Model shop: fine-cut cylinders finished brass faces.

Material Comparison: Fine Cut vs Standard Cut on Small Cylinders
What the dense tooth pitch changes:
| Factor | Fine Cut (this bit) | Standard Cut |
|---|---|---|
| Tooth pitch | Dense – many points | Sparse – fewer points |
| Bite per pass | Light, controlled | Heavier |
| Flat work | Spreads contact evenly | Concentrates |
| Small features | No breakout | Dig risk |
| Finish | Fine | Coarser |
Delivery Scope
Bits in tube; fine and standard cut stocked.
