Straight Pencil Grinder 51756
The Dynabrade 51756 is a straight pneumatic pencil grinder rated at 0.1 hp with a maximum free speed of 35,000 RPM. It accepts a 1/8 in collet for small-diameter accessories and connects to a compressed-air supply through a 1/4 in NPT female inlet. The tool is intended for precision deburring, grinding and finishing in metalworking, mould-making and maintenance tasks.
Bare tool with 1/4 in whip hose
The package contains the bare grinder and a whip hose with a 1/4 in internal diameter. No additional collets, lubricators, filters or carrying case are included. The rear exhaust directs airflow away from the workpiece, and a non-slip grip aids control during extended use. There is no lock-on, lock-off or brake mechanism fitted.
Verify air supply and accessory compatibility
Before ordering, confirm that your compressor can deliver the pressure and flow required for a 0.1 hp pneumatic motor at 35,000 RPM through a 1/4 in NPT connection. Ensure the 1/8 in collet matches the shank diameter of the burrs, mounted points or carbide tools you plan to run. Check that your air line includes appropriate filtration and lubrication for reliable operation.

Questions about this item
How often should the 1/8 in collet be inspected or replaced on the Dynabrade 51756?
Inspect the 1/8 in collet regularly for wear or run-out; replace it when gripping force drops or the shank slips during operation.
What limits continuous running at 35000 RPM on the Dynabrade 51756?
Sustained 35000 RPM is limited by air supply capacity and heat buildup in the motor housing; maintain clean, dry air at the required pressure.
How much noise and heat does the 0.1 hp motor produce during all-day use of the Dynabrade 51756?
The rear exhaust directs noise away from the operator; the 0.1 hp motor runs cool with adequate airflow, and the non-slip grip stays comfortable.
