Engineered specifically for high-productivity industrial environments, this series delivers a powerhouse performance without sacrificing operator comfort or tool longevity.
Power Meets Low-Profile Design
The standout feature of the CP3450 Series is its unique low-profile angle head design. If you’ve ever struggled to prep a surface in a cramped corner or a restrictive joint, you know how crucial a streamlined tool head is.

- Versatile wheel capacities ranging from 4” (100 mm), 4.5” (115 mm), to 5” (125 mm)Â

- Constant Lubrication: A specialized bevel gear design keeps the tool constantly lubricated, drastically reducing wear and extending the life of the grinder.
- Premium Handling & Comfort: Built with a rugged steel housing wrapped in an insulating composite over-housing, it protects the operator’s hands from temperature extremes while providing a secure grip.
