  • Variable-speed control with 60,000 RPM free speed

  • Low 0.86 CFM average air consumption at 15 seconds

Compact Pencil Grinder for Precision Work

The Dynabrade 52855 is a straight pneumatic pencil grinder built for detailed finishing and deburring tasks. It accepts a 3 mm collet for small accessories and runs on compressed air through a 1/4 in NPT female inlet. A 5 in whip hose is included for immediate connection.

Upgrade from Basic Rotary Tools

This grinder replaces lower-speed rotary tools when precision and consistent power are required. The jump is justified for operators who need 60,000 RPM free speed and 0.1 hp output in a lightweight 0.7 lb body. Variable speed control allows fine adjustment for delicate materials.

Air Supply Limits Define Performance

Operation requires 90 psig at the tool with a minimum 1/4 in hose diameter. Average consumption is 0.86 CFM during a 15 second run and 0.9 CFM under full load. Rear exhaust directs airflow away from the work surface. Inadequate compressor capacity will reduce speed and torque.
