CNC Bit Reference — About This Database
This database covers CNC router bits compatible with the Wolfpawn 4040 Pro and similar desktop CNC machines with ER11 collets.
Shank Sizes
Only two shank sizes are listed — the two that actually fit desktop CNC ER11 collets:
| Shank | Collet | Notes |
|---|---|---|
| 1/8" (3.175mm) | Stock ER11 collet (ships with most machines) | Most common for desktop CNC |
| 1/4" (6.35mm) | Requires 1/4" ER11 collet adapter | More rigid, better for hardwood and larger passes |
Router table bits (1/2" shank, 3/8" shank) are NOT listed — they do not fit ER11 collets and are not suitable for desktop CNC spindles.
Bit Types Covered
- Spiral bits — upcut, downcut, compression, O-flute (for plastics)
- V-bits — 15°, 20°, 30°, 45°, 60°, 90° — for V-carving, engraving, chamfers
- Ball nose — for 3D relief carving, micro sets (0.8–2.5mm)
- Straight bits — for dadoes, rabbets, joinery
- Specialty — surfacing/spoilboard bits, engraving liners
Brands Covered
- Genmitsu — branded bits sold through SainSmart, designed for their desktop CNC line. The OS10B, MC40A, VG05B, WC04A, BN10A, USBC05, DSBC05 series.
- Generic — universal bit types that apply regardless of brand. Use these settings as a starting point and adjust for your specific bits.
How to Use This Database
Each profile lists:
- Specs — shank, coating, material, max RPM
- Settings — RPM, feed rate (mm/min), depth of cut (mm per pass)
- Applications — what materials/operations the bit is suited for
- Tips — practical notes on when and how to use it
Settings are conservative starting points for the Wolfpawn 4040 Pro. Run a test cut on scrap before committing to a full job.
