Straight Die Grinder 1.0 hp 20,000 RPM
The Dynabrade Products 52669 is a straight die grinder built for precision metalworking and deburring tasks. Its lightweight composite housing reduces operator fatigue during extended use. The gearless design minimises maintenance while delivering consistent power. This tool suits professionals in automotive, aerospace and fabrication shops.
1/4 in Collet Capacity
The 1/4 inch collet determines which carbide burrs, mounted points and accessories can be secured. It accepts standard 1/4 inch shank tooling used in general material removal. Buyers needing 3/8 inch or 6 mm shank compatibility must select a different model. Verify accessory shank size before purchase.
Sustained Air Consumption 11.0 CFM
At full load the grinder draws 44.0 CFM, but the average consumption over a 15 second run is 11.0 CFM at 90 psi. This lower sustained figure reflects typical intermittent operation and helps size the compressor correctly. The anti-clog exhaust baffling maintains airflow during prolonged sessions. Rear exhaust directs air away from the workpiece.

Questions about this item
What does the 20,000 RPM free speed mean for material removal in the shop?
At 20,000 RPM free speed the grinder delivers rapid stock removal on metal, composites and plastic, with the 1.0 hp motor maintaining torque under load for consistent finish quality.
How does the 1/4 in NPT air inlet and 44.0 CFM full-load flow affect compressor sizing?
The 1/4 in NPT inlet requires a 3/8 in minimum hose and a compressor capable of sustaining 44.0 CFM at 90 psi to run the tool at full power without pressure drop.
What clearance does the 8 3/4 in overall length and composite body need for tight work areas?
The straight, gearless body measures 8 3/4 in long and uses a lightweight composite housing, allowing access in confined spaces while the rear exhaust directs air away from the workpiece.
