What is an Air Die Grinder?
An air die grinder is a miniature, handheld rotary tool that uses compressed air to spin a mounted accessory at high speeds, usually between 15,000 and 25,000 RPM. With pneumatic motors that can spin at 25000 RPM, RONGPENG RP17313 air die grinders make quick work of tasks like removing welds, smoothing rough surfaces, and polishing.
At the heart of the tool is a small, high-speed air turbine that converts kinetic energy from compressed air into rotary mechanical energy. The spindle lock allows you to change accessories quickly. Common accessories include grinding stones, cut-off wheels, sanding drums, polishing pads, and engraving points. Filters help keep abrasive dust out of the turbine. An adjustable trigger gives you control over the speed.
Uses for an Air Die Grinder
The uses of an air die grinder are vast and diverse. It is primarily employed for tasks that require grinding, deburring, polishing, or shaping materials such as metal, plastic, or wood.

How to Use an Air Die Grinder for Best Results
Select the Right Accessory
Air grinders come with a variety of attachments, such as grinding wheels, cutting wheels, sanding pads, and polishing buffs. Each attachment is designed for a specific task, so choose the one that best fits your needs. Here are some of the most common accessories and their uses.
Cutting discs for slicing, slotting, or gouging metals. Use reinforced fiberglass discs.
Grinding stones in 24-60 grits to rapidly remove material. Go with silicon carbide or aluminum oxide.
Abrasive flapwheels for blending and deburring in one step. Opt for zirconia or aluminum oxide grits.
Bristle discs that won't load up quickly when finishing stainless steel or other gummy metals.
Felt bobs and cotton buffing wheels with polishing compounds for final finishing.
Grinding Techniques
The key to flawless results with an air die grinder is letting the tool do the work through gentle guidance. Avoid pressing too hard or lingering in one spot, which can cause gouges, uneven surfaces, or burns. Here are some tips:
Brace yourself and the workpiece so you have full control over the grinding tool. Be prepared for the torque.
Hold the grinder at a 15-30° angle to the worksurface. Let the edge of the accessory contact the metal.
Use smooth, sweeping motions in the direction of the accessory's rotation. Avoid sudden lateral movements.
Apply even, light pressure and regularly reposition the grinder to distribute wear.
When finished, run the grinder off the workpiece while still spinning to avoid dwell marks.
For cleanup passes, reduce pressure and switch to finer grit accessories.
Setting up the Air Die Grinder
Install an air filter/regulator/lubricator unit close to the air supply.
Adjust regulator to 90 PSI maximum for most die grinders. Use lower pressure for extended tool life.
Fill lubricator with air tool oil to maintain adequate lubrication to the grinder.
Blow out dust from the grinder with compressed air after each use.
Inspect accessories for damage like cracks or loose bonding. Discard worn accessories.
Choosing the Right Air Die Grinder
