Check the fit
This model suits a job that calls for a 6 mm straight cut and the chip-breaker type named in the selector. The listing does not define the chip-breaker geometry beyond its name.
- Confirm that the router collet accepts the 1/2 in shank.
- Use the 6 mm diameter to check slot width and the 20 mm cutting length to check depth.
- Compare the cutter profile with the selector chip-breaker label.
- Secure the work. Follow router and cutter instructions for speed and feed, then test on scrap.
Limits in the listing
