Sanders

Pneumatic grinders for grinding, polishing, and cutting off. Choose from straight or angled models. The length determines reach, the maximum RPM the working speed. Watch air consumption and noise output. An undersized compressor reduces performance. Check the air inlet thread and working pressure before you order. This helps you select the right grinder for your workshop.

How to choose the right air grinder

Straight or angle, which version fits?

A straight air grinder works best for precise tasks in a straight line. An angle version reaches tight spots and suits cutting off. The length determines your reach. Short tools around 170 mm give control. Extra long versions up to 376 mm reach deeper into engine bays or between chassis parts.

Watch RPM and working pressure

The maximum RPM sets how fast you grind or polish. Higher speeds work quicker but need more air. Compare the tool's air consumption with your compressor's output. A small compressor cannot deliver enough pressure. The tool loses power and the job takes longer. The required working pressure is often stated in bar or psi.

Where ordering goes wrong

Check the air inlet thread. Most tools use a 1/4 inch female thread, but exceptions exist. Measure the collet or arbor size too. A straight grinder often takes a 6 mm collet, a cut-off tool an arbor of 16.2 mm. If the fitting does not match, the tool will not run. Consider noise and vibration for long sessions. Pick a version with lower noise levels then.

These sanders fall under air tools for the workshop. Use them on bodywork and they pair well with spray guns. For rust and paint choose sandblasting equipment, and with air blow guns you blow away swarf. Make sure your air tool accessories and hoses fit your connection.
