Product Identity
The Dynabrade 48360 is a straight die grinder built for heavy-duty material removal. It serves technicians working on carbon fibre, composites, fibreglass and metal where precision and sustained power matter.
Capacity and Headroom
A 0.4 hp motor spins the 1/4 in or 6 mm collet at 20 000 RPM for fast stock removal. The composite housing keeps weight down during extended use, while the safety-lock throttle lever prevents accidental starts. Continuous high-load grinding will eventually exceed the motor's thermal limits.
Interface Limits
The tool connects via a 1/4 in NPT female air inlet, requiring a compatible supply hose and sufficient compressor flow. Performance drops if line pressure falls below the grinder's demand, and the fixed collet sizes restrict accessory shank diameters to the two supplied inserts.

Questions about this item
Will the 0.4 hp straight die grinder keep up with my existing 1/4 in NPT air hose and fittings?
Yes, the tool uses a 1/4 in NPT female air inlet that threads directly onto standard 1/4 in NPT male hose ends.
How do I verify the grinder is running at the rated 20000 RPM after I connect it?
The safety-lock throttle lever engages smoothly and the motor spins freely; listen for a steady high-pitched tone without vibration, which indicates full speed.
Does the box include both the 1/4 in and 6 mm collet inserts, or do I need to buy one separately?
Both collet inserts are supplied — part 01485 for 1/4 in and part 01497 for 6 mm — so no extra purchase is required.
