Pro Tips

- Make a test groove on scrap material first to confirm the width, depth and finish before cutting the final workpiece.
- Use several light passes for cleaner results, especially on hardwood or delicate craft pieces.
- Secure the workpiece firmly and guide the tool smoothly to avoid chatter marks in the groove.

- Check that the bit is seated straight and tightened properly before switching the tool on.
- Set the speed according to the material being cut, using the recommended range for hardwood or softwood.
- Secure the workpiece firmly with a clamp or suitable holding method.

- Switch off the tool and allow the bit to stop completely before removing it from the workpiece.
Safety
- Wear eye, ear and dust protection when using rotary cutting accessories.
- Always use the correct tool and accessory for the job.
- Make sure the bit is securely tightened in the collet before switching on the tool.
