Built for production drilling, aerospace assembly, metal fabrication, and industrial maintenance, the Dotco 14CNL91-51 pneumatic drill combines a 0.9 HP motor with a 5,200 RPM free speed to provide fast, controlled drilling in metal, composite, and general manufacturing applications. As part of the 14CNL Series, this non-reversible drill delivers consistent air-powered performance for repetitive production work where reliability and speed are essential. Its rear exhaust design helps direct spent air away from the work surface, improving visibility while reducing debris around the drilling area.
The high-speed motor allows operators to complete drilling operations efficiently while maintaining excellent control during precision work. Pneumatic operation also eliminates concerns about motor overheating during extended production cycles, making this drill well suited for assembly lines, aircraft manufacturing, maintenance facilities, and fabrication shops where dependable performance is required throughout the workday.
