1 HP Air Straight Die Grinder

The Capri Tools CP32500 is a pneumatic straight die grinder built for heavy-duty metalworking and fabrication tasks. Its 1 HP motor delivers the power needed for grinding, porting and polishing in professional automotive and industrial shops.

Built-in air regulator and low vibration

The integrated regulator lets you fine-tune speed on the fly, replacing tools that run at a fixed rate. Ultra-low vibration at 0.45 m/s2 and quiet operation at 78 dBA make the upgrade worthwhile for technicians who work long shifts and need reduced fatigue.

4.1 CFM at 90 PSI air consumption

The grinder runs on modest shop air, comfortably handling extended deburring and weld cleanup sessions. Rear exhaust with 360-degree swivel directs airflow away from the work. Very high-volume material removal may exceed the 1 HP output, and the 1/4 in. NPT inlet limits hose options to that thread size.

Questions about this item

What size air inlet fitting does the CP32500 die grinder require?

The grinder comes with a 1/4 in. NPT air inlet fitting for connection to your air supply.

How do I adjust the speed on this air straight die grinder, and what step is often missed?

Use the built-in air regulator to fine-tune speed; the step often missed is setting the regulator while the tool is running at 90 PSI to match the 4.1 CFM consumption.

When should I service the muffler or exhaust on this 1 HP die grinder?

Inspect the specially tuned muffler and 360-degree swivel rear exhaust if noise rises above 78 dBA or vibration exceeds 0.45 m/s² during operation.
