✅ Recommended Machining Parameters
- Feed speed: 8–12 m/min
- Spindle speed: 18000–22000 RPM
✅ Operation Guide
- This woodworking router bit is designed for handheld and bench CNC engraving machines. Not suitable for electric drills or drill presses.
- Suitable for hardwood, softwood and composite boards. Do NOT cut metal, sand or stone materials.
- Use matched high-quality collets. Replace worn, out-of-round or tapered collets to avoid vibration or shank breaking.
- Fully insert the shank into the collet and fasten tightly. Partial clamping will cause shank fracture.
- Stop the machine immediately if runout occurs, re-clamp the tool properly.
- Wear eye and ear protection during operation. Keep clothes and body away from rotating cutter.
✅ Tool Maintenance
- Clean resin and wood chips after use with industrial solvent.
- Apply thin machine oil to prevent rust; clean shank to avoid slipping.
- Do not regrind or modify the cutter arbitrarily, improper grinding will cause edge chipping.
✅ Troubleshooting Reference
- Cutter breakage: Reduce feed rate, shorten tool overhang, check collet and spindle tightness, reduce cutting depth
- Cutting edge chipping: Adopt climb milling, improve workpiece fixing, adjust cutting parameters
- Rapid edge wear: Check matched material, adjust spindle speed and feed speed
- Poor surface finish: Increase spindle speed, replace worn cutter, add cooling, reduce tool overhang

| Problem | Cause | Solution |
|---|---|---|
| Cutter Breakage | Feed rate too fast, spindle speed too low | Reduce feed rate or increase spindle speed; recommended speed ≥20000 RPM for engraving machines |
| Excessive cutting depth | Reduce cutting allowance | |
| Too much tool overhang, insufficient clamping length | Minimize overhang; keep clamping length ≥4× shank diameter | |
| Severe cutting edge wear | Resharpen the cutter or reduce cutting speed | |
| Poor collet accuracy | Replace the collet | |
| Loose spindle or collet | Adjust spindle and collet | |
| Complex cutting geometry with many dead corners | Optimize cutting parameters and programming strategy | |
| Unstable workpiece clamping | Improve fixture to fix workpiece firmly | |
| Poor chip evacuation, heavy chip adhesion | Reduce feed rate, chamfer edge with diamond file to blunt cutting edge | |
| Cutting Edge Chipping | Feed rate too fast, cutting edge too sharp or sharp tip angle | Reduce feed rate, chamfer edge with diamond file to blunt cutting edge |
| Low-precision or improperly installed collet | Replace collet or clear chips inside the collet | |
| Insufficient rigidity of fixture | Lower cutting parameters | |
| Complex workpiece shape with many dead corners | Adjust cutting parameters and programming | |
| Unstable workpiece installation | Improve fixture for stable clamping | |
| Incorrect cutting direction | Use climb milling | |
| Impurities inside workpiece material | Check raw material and adjust cutting speed | |
| Rapid Edge Wear | Spindle speed too high or feed rate too low | Reduce spindle speed or increase feed rate |
| Low precision of spindle or collet | Repair spindle precision or replace collet | |
| Poor chip evacuation, chips sticking on edge | Select proper tool model and improve chip removal | |
| Wrong tool selection for workpiece material | Confirm material and select matched router bit | |
| Improper cutting fluid | Choose suitable cutting fluid | |
| Incorrect cutting direction | Adopt climb milling | |
| Poor Surface Finish | Feed rate too fast or spindle speed too low | Reduce feed rate or raise spindle speed |
| Severe tool wear | Replace the cutter | |
| Low sharpening precision | Use brand-new cutter for finishing operation | |
| Excessive chip accumulation | Clear chips and optimize cooling method | |
| No cooling system | Apply proper cooling system such as water cooling | |
| Tool vibration | Use high-rigidity high-precision collet and shorten tool overhang | |
| Unqualified cutting effect | Choose larger diameter cutter or high-precision engraving machine |
