When routing larger-profile composite components or performing demanding edge-finishing operations, the Dotco 12L4018-03 Inline Router delivers the power and control needed for consistent production results. Equipped with a 1.7 HP pneumatic motor and a 18,000 RPM free speed, this router provides smooth cutting performance while accommodating 3/8" shank router bits for applications requiring larger tooling. Its lightweight composite housing helps reduce fatigue during prolonged use, and the inline configuration promotes accurate tool alignment for controlled routing.
As a member of Dotco's 12-40 Series, this inline router is well suited for aerospace composites, fiberglass fabrication, plastic machining, and industrial manufacturing environments where compressed-air tools are preferred. The combination of higher horsepower and larger bit capacity makes it an excellent choice for heavier routing applications while maintaining precise operator control.
