Choosing between PC9030 and PC5300:
Best for general finishing, small holes, and high-precision parts. Provides the smoothest surface finish.
Best for interrupted cuts, roughing, or unstable setups. More resistant to impact and chipping.
Machinist's Tip: If your work material is very gummy and sticks to the tool, PC9030 is your best first choice.
