Heavy-Duty Straight Die Grinder

The Dynabrade 48327 is a composite straight die grinder built for heavy-duty material removal. It accepts both 1/4 inch and 6 mm collet inserts for versatile accessory mounting. The tool connects to a compressed air supply via a 1/4 inch NPT female inlet. A safety-lock throttle lever prevents accidental activation during handling.

Sustained High-Speed Operation

Rated at 0.4 hp, the motor maintains 30,000 RPM under continuous load for consistent cutting performance. The composite housing reduces vibration transmitted to the operator during extended sessions. The safety-lock throttle requires deliberate engagement, supporting controlled operation over long periods. This design targets steady material removal rather than short bursts.

Compressed Air Interface Limits

The 1/4 inch NPT female inlet sets the maximum practical airflow the tool can receive from the supply hose. Performance depends on the compressor and line pressure delivering sufficient volume at the inlet. The included collet inserts (Mfr. No. 01485 and 01497) define the compatible shank diameters for mounted accessories. No electric power or battery interface is present.

Questions about this item

How much noise and heat does the 0.4 hp motor produce during extended use?

The composite body reduces vibration and stays cooler to the touch than metal housings, while the safety-lock throttle lets you feather the 30000 RPM speed to keep noise manageable.

What fittings and collets must I already have to run this grinder?

Your air hose needs a 1/4 in NPT male thread to match the tool's female inlet, and the box already includes 1/4 in collet insert 01485 plus 6mm collet insert 01497.

Will the 1/4 in NPT air inlet work with my existing compressor setup?

Yes, the inlet is a standard 1/4 in NPT female port, so any hose with the matching male thread connects directly without adapters.
