Check the fit
Use the dimensions to check slot width and depth. Choose the chip-breaker option only when that profile matches the cutter you need. The listing does not describe a performance difference.
- Confirm that the router collet accepts the 1/2 in shank.
- Use the 8 mm diameter and 20 mm cutting length to check the intended slot.
- Compare its chip-breaker label with the straight-cutter label on MCRT28.
- Secure the work. Follow router and cutter instructions for speed and feed, then test on scrap.
Limits in the listing
The source drawing does not show overall length. The listing also omits maximum speed, feed rate and compatible router models. Follow the machine maker's instructions for those values.
