DOTCO

DOTCO is a brand of pneumatic tools and replacement components, primarily serving industrial finishing, deburring, drilling, and grinding applications. The brand is recognized for its range of air-powered pencil grinders, die grinders, drills, and associated service parts such as rotor blades and guards. DOTCO tools are designed for continuous-duty use in manufacturing, metalworking, and assembly environments where compressed air is the primary power source. Typical specifications across the product line include horsepower ratings from 0.1 hp to 0.9 hp, maximum speeds ranging from 500 RPM to 60,000 RPM, and collet sizes of 1/8 in. or 1/4 in. for grinders. Drill models feature 1/4 in. keyed chucks and reversible operation. The tools are offered as bare tool units, without integrated lubrication systems in some models (oil-less rotor blades are available as replacements). Exhaust configurations include rear exhaust for reduced debris blowback. DOTCO replacement parts—such as rotor blades (part numbers 2253PT, 2906) and guards (part number 14-1258)—are compatible with specific tool models, enabling maintenance and extended service life. 3G Electric stocks over 80 SKUs of DOTCO air tools and replacement parts, covering pencil grinders, straight die grinders, right-angle drills, and service components. The inventory includes both current-production tools and legacy-compatible parts, supporting plant engineers and maintenance managers who need to maintain existing equipment or specify new pneumatic tools for precision material removal. All products are sourced through standard industrial distribution channels; no exclusive or proprietary modifications are claimed. Specifications are drawn from manufacturer data and are verifiable against DOTCO part numbers. 3G Electric provides global shipping for these items, with technical support available for specification matching and part number cross-referencing.
