Heavy-duty straight die grinder
The Dynabrade 51300 is a 0.5 hp straight die grinder built for heavy-duty material removal. It runs at a maximum speed of 24000 RPM and connects via a 1/4 in NPT female air inlet. The tool includes a safety-lock throttle lever to prevent accidental starts.
Upgrade from lighter pneumatic grinders
This model replaces lower-horsepower die grinders when sustained cutting or grinding power is required. The jump is worth it for operators who need consistent torque at high RPM for deburring, porting or weld cleanup on steel and aluminium.
Fits standard shop air systems
The 1/4 in NPT female inlet connects directly to common shop air lines without adapters. Four collet inserts are included: 1/4 in, 3/8 in, 6 mm and 8 mm, covering the most common carbide burr and mounted point shanks. The straight body suits tight-access work where angled tools cannot reach.

Questions about this item
What size air hose fitting does the 1/4 in NPT female inlet need?
Connect a 1/4 in NPT male fitting to the inlet; use thread sealant or tape to prevent leaks at the connection.
How is the Safety-Lock Throttle Lever engaged before the grinder runs?
Depress the lock lever with your thumb while squeezing the throttle; releasing the lock returns the lever to the off position automatically.
When should the supplied collet inserts 50013, 50014, 50016 and 50039 be replaced?
Replace an insert when the shank slips, the collet nut will not tighten fully, or the insert shows visible wear or cracking.
