Chicago Pneumatic CP3000-325R Straight Die Grinder
The Chicago Pneumatic CP3000-325R is a straight die grinder built for heavy-duty material removal and precision finishing tasks. It delivers 0.4 horsepower at a maximum speed of 25,000 RPM, making it suitable for metalworking, deburring, and weld preparation. The tool operates on compressed air with a 1/4 inch NPT female inlet connection.
Upgrading from lower-speed
This grinder replaces underpowered rotary tools that stall under load or lack the RPM for fine carbide burr work. The jump is worth it when your current tool cannot maintain speed during sustained grinding or when you need a 1/4 inch collet capacity for larger accessories. It is not for buyers who require an angled head for tight corners or an electric motor for cordless portability.
Sustained-load behaviour with 0.4 hp air motor
Under continuous load the 0.4 hp motor maintains consistent torque to prevent stalling during extended material removal. The streamlined safety lever allows precise throttle control for long sessions without hand fatigue. The barrel grip design directs vibration away from the operator during prolonged high-speed operation.
