Dynabrade 51700 Straight Pencil Grinder
The Dynabrade 51700 is a straight pencil grinder built for precision material removal in tight spaces. It suits metalworkers and fabricators who need controlled high-speed performance for detail grinding, deburring or finishing tasks.
Check air supply and collet compatibility
Verify your compressed-air system delivers sufficient flow at the required pressure for a 0.1 hp motor running up to 60 000 RPM. Confirm the 1/4 in NPT female inlet matches your hose fittings and that the 1/8 in collet accepts the accessories you intend to use.
Upgrades from basic rotary tools
This grinder replaces lower-speed rotary tools when finer finish quality and faster stock removal are needed. The jump is worth it for operators who work long shifts and value the non-slip grip, though it lacks a lock-off switch or brake for applications requiring those safety features.
