Dotco 12L1381-36 Gearless Right Angle Grinder | 12-13 Series | 0.3 HP | 25,000 RPM | 1/4" Collet | Composite Housing | Rear Exhaust

Built for precision deburring, weld cleanup, and detailed finishing in confined work areas, the Dotco 12L1381-36 Gearless Right Angle Grinder combines a 0.3 HP pneumatic motor with a 25,000 RPM free speed to provide controlled material removal on metal and composite components. Its compact right-angle head improves accessibility around corners, inside assemblies, and recessed surfaces, while the 1/4" collet accommodates a broad range of compatible carbide burrs and mounted abrasive accessories. The gearless direct-drive design delivers smooth power transmission with fewer drivetrain components, and the composite housing helps reduce overall tool weight for improved handling during extended operation.

Equipped with a rear exhaust, this 12-13 Series grinder directs discharged air away from the front of the tool to help minimize airflow across the work surface during precision finishing. Its 25,000 RPM operating speed offers an excellent balance between material removal and control, making it suitable for production manufacturing, maintenance departments, aerospace fabrication, and general metalworking applications.

FAQs:

• Q: How does the 12L1381-36 differ from the 12L1380-36?
  A: Both models feature a rear exhaust, composite housing, and 1/4" collet. The primary difference is free speed—the 12L1381-36 operates at 25,000 RPM, while the 12L1380-36 is rated at 30,000 RPM.
• Q: Why would I choose a rear exhaust grinder?
  A: Rear exhaust directs discharged air away from the front of the tool, helping minimize airflow over the work surface during detailed grinding and finishing operations.
• Q: What accessories are compatible with the 1/4" collet?
  A: The grinder accepts compatible 1/4" shank carbide burrs and mounted abrasive accessories. Always use accessories rated for at least the tool's maximum speed of 25,000 RPM.
• Q: What does the gearless design offer?
  A: The gearless direct-drive configuration transfers power without a conventional gear train, helping provide smooth operation with fewer moving drivetrain components.
