When fast, controlled material removal is required in confined work areas, the Dotco 12L1300-36 Gearless Right Angle Grinder delivers the combination of a 0.3 HP pneumatic motor and a 30,000 RPM free speed to support precision deburring, edge blending, and surface finishing. Its compact right-angle configuration improves access around fixtures, inside corners, and welded assemblies, while the 1/4" collet accommodates a wide selection of carbide burrs and mounted abrasive accessories. The gearless direct-drive design provides smooth power delivery with fewer moving drivetrain components, and the composite housing helps reduce overall tool weight during extended operation.
Featuring a front exhaust, the 12-13 Series grinder helps direct discharged air away from the operator while working in close quarters. Its higher 30,000 RPM speed is well suited for fine finishing and rapid stock removal with properly rated accessories, making it an excellent choice for production manufacturing, maintenance departments, aerospace fabrication, and precision metalworking applications.

A: The grinder accepts standard 1/4" shank carbide burrs and other compatible mounted abrasive accessories designed for high-speed pneumatic grinders. - Q: Why use a right-angle grinder instead of an inline grinder?
A: The right-angle head offers improved access to tight spaces, inside corners, and side surfaces that are difficult to reach with a straight grinder. - Q: What is the purpose of the front exhaust?
A: Front exhaust helps direct discharged air away from the operator's hand while assisting with chip and debris clearance near the work area.
