Chicago Pneumatic Tools and Equipment

Chicago Pneumatic: Over a Century of Pneumatic Tool Excellence

Chicago Pneumatic — known industry-wide simply as "CP" — stands as one of the most storied names in professional-grade power tools. Chicago Pneumatic traces its origins to 1901, when founder John W. Duntley incorporated the company and immediately patented its first single-valve pneumatic hammer, establishing a philosophy of practical engineering innovation that persists to this day. Now a subsidiary of Atlas Copco AB, the brand's products reach professionals in more than 150 countries across vehicle service, industrial manufacturing, construction, and mining.

Built for the Demands of Real Work

What has kept Chicago Pneumatic at the forefront of the industry is a consistent commitment to durability, ergonomics, and performance under pressure. The brand serves three core application segments — manufacturing, maintenance, and construction and demolition — with a product portfolio wide enough to equip an entire workshop. From lightweight composite-body tools designed for operator comfort, to heavy-duty steel-housing variants engineered for the toughest industrial environments, CP tools are built around the real demands of professional use.

CP's impact wrenches are arguably the brand's most iconic product category. Chicago Pneumatic is credited with designing the world's first impact wrench, and that legacy of torque-driven innovation continues through modern lines featuring rocking dog, twin hammer, and pin clutch mechanisms. Whether you need a compact stubby wrench for tight engine bays or a heavy-duty 1-inch drive unit for truck and fleet work, CP impact wrenches deliver the consistent output professionals rely on.

Alongside impact wrenches, Chicago Pneumatic's air hammer retainers are essential accessories for any shop running CP percussive tools. These retainers — including quick-change and spring-style designs — ensure that chisels and bits stay securely locked during high-vibration operation, protecting both the tool and the technician.

For precision metalwork, the brand's die grinders are widely praised for their balance of power and control. Suited for grinding weld seams, removing rust, and polishing rough edges, CP die grinders are a trusted choice across automotive body shops and fabrication facilities. Complementing them, CP's angle grinders — spanning multiple industrial series — offer the aggressive material removal capabilities needed for heavy-duty cutting and surface preparation tasks.

Rounding out the workshop toolkit, Chicago Pneumatic also manufactures shop presses, purpose-built for pressing bearings, bushings, and other press-fit components in vehicle service environments. The availability of genuine OEM spare parts kits for CP presses speaks to the brand's commitment to long-term serviceability.
