Air Die Grinder CP875 Kit - Compact 22500 RPM Right Angle Tool

Our review of the CP875 Kit finds it best suited to technicians and hobbyists who need a compact, high-speed air die grinder for tight spaces. The single biggest reason to buy is the combination of a 0.3 HP / 220 W motor and a 22500 RPM top speed in a 90 degree angle head, which delivers enough power for grinding, polishing, and deburring while remaining easy to handle during extended use.

Key Features

• High speed and power: The 0.3 HP / 220 W motor and 22500 RPM maximum give fast material removal and quick polishing with common surface conditioning accessories.
• Compact right angle design: The 90 degree head and lightweight construction make it easy to reach tight or awkward areas without excessive user fatigue.
• Safety throttle lever: The built-in safety lever reduces accidental starts and adds operator confidence when working in confined spaces.
• Accessory kit included: The CP875K ships with a 2 in backing pad and a range of coarse, medium and fine surface prep pads plus multiple sanding discs to start common jobs right away.
• Durable construction: Rear exhaust and an aluminum housing provide durability for maintenance and shop environments.

Who It's For

This tool is aimed at automotive detailers, metalworkers, welders and DIYers who need a small but potent die grinder for polishing stainless, porting heads, or removing weld seams in tight engine bays. The included kit makes it useful for users who want an out-of-the-case solution for surface prep and sanding.

Users who need heavier, continuous industrial grinding or an electric alternative for dust-sensitive indoor work should look elsewhere; this pneumatic tool requires an air supply and is optimized for intermittent high-speed tasks rather than nonstop heavy stock removal.

Pros & Cons
