0.7 hp Right-Angle Die Grinder
The Dynabrade 54359 is a pneumatic right-angle die grinder built for metal fabrication, weld cleanup and deburring in tight spaces. Its composite housing keeps weight low during extended use. A 1/4 in collet accepts standard carbide burrs and mounted points. The tool runs at 18,000 rpm free speed with a 0.7 hp motor.
Who it suits and who it does not
Technicians who need a lightweight angle grinder for intricate porting, blending or rust removal will benefit from the compact right-angle head and rear exhaust. Shops without a 90 psi compressed-air supply delivering at least 41 CFM at full load should look elsewhere. The absence of variable-speed control also makes it less suited for applications requiring adjustable rpm.
Deciding specification: 18,000 rpm free speed
The 18,000 rpm free speed determines material removal rate and accessory compatibility. Verify that your consumables are rated for this speed before purchase. If your process demands lower or selectable speeds, a different grinder will be required.

Questions about this item
What does the 1/4 in NPT air inlet mean for my compressor hose?
The tool uses a 1/4 in NPT female thread so you need a matching male fitting; the spec also calls for a minimum 1/4 in hose ID and 90 psi operating pressure to deliver the rated 0.7 hp at 18,000 RPM.
How much room does the 7 7/8 in overall length and 2 29/32 in right-angle head need in a tight engine bay?
The grinder measures 7 7/8 in long with a compact 2 29/32 in right-angle head, so it fits in confined spaces while the composite handle keeps the tool light for extended use.
Do I need to oil the gearless ball-bearing motor before the first 15-second test run?
No oil is required for the gearless ball-bearing design; simply connect clean dry air at 90 psi, run the tool for 15 seconds to verify the average 10.25 CFM flow, then begin work.
