1/4 Inch Shank Burrs Tool Bit, 6 mm Double Cut Carving Grinder Bit
6 mm double-cut carbide carving bit on a 1/4 inch shank – the standard bench burr for steel, cast iron and hardwood.
Design and Construction
A single 6 mm double-cut carbide head on a 1/4 inch shank – the general-purpose bench burr. YG-series integral carbide, ground with crossed flutes that stay sharp through daily shop work.
How It Works
The crossed flutes cut in both directions of sweep, so left- and right-handed operators get the same controlled bite at 6,000-50,000 RPM.
Applications
General deburring, weld dressing, carving and shaping on metal and hardwood, fabrication touch-up.
Field Cases
- Welding bench: knocks down arc-start craters on plate edges before painting.
- Woodworking shop: shapes hardened jig components that HSS bits burn.
- Art studio: carves detail into corten-steel sculpture panels.
Performance Data
| Metric | Value / Observation |
|---|---|
| Head diameter | 6 mm |
| Shank | 6 mm (1/4″) |
| Edge hardness | 1,300-1,500 HV |
| Life vs HSS | About 5-10x on steel (typical) |
Suitable Materials
Steel, cast iron, stainless steel, non-ferrous metals and hardwood.
Material Comparison: Same 6 mm Job, Three Tools: Carbide vs HSS vs Mounted Stone
Typical industry data for a 6 mm blending job on steel:
| Factor | Carbide Burr (this bit) | HSS Burr | Mounted Stone |
|---|---|---|---|
| Edge hardness | 1,300-1,500 HV | 240-300 HV | Abrasive bond |
| Life vs HSS | 5-10x on steel above 35 HRC | Baseline | Glazes in minutes |
| Speed, 6 mm in steel | About 50,000 RPM starting | Lower – flutes roll over | Glaze-limited |
| Corner capability | Sharp internal corners | Rounds quickly | Radius only |
| Cost per part | Lowest over tool life | Higher – short life | Consumable adds up |
