Dotco 12L1382-36 Gearless Right Angle Grinder | 12-13 Series | 0.3 HP | 20,000 RPM | 1/4" Collet | Composite Housing | Rear Exhaust

Built for controlled deburring, weld blending, and precision material removal in restricted work areas, the Dotco 12L1382-36 Gearless Right Angle Grinder combines a compact right-angle design with a 0.3 HP pneumatic motor and a 20,000 RPM free speed for smooth, consistent performance. Its 1/4" collet accepts a wide variety of compatible carbide burrs and mounted abrasive accessories, while the gearless direct-drive configuration helps provide efficient power transfer with fewer moving drivetrain components. The composite housing keeps the tool lightweight and easy to maneuver during repetitive finishing operations.

Equipped with a rear exhaust, this 12-13 Series grinder directs discharged air away from the front of the tool, helping reduce airflow across the workpiece during detailed grinding and finishing. The 20,000 RPM operating speed offers excellent control for precision edge preparation, casting cleanup, and surface finishing in manufacturing, aerospace, maintenance, and fabrication environments.

FAQs:

• Q: How does the 12L1382-36 compare to the 12L1381-36 and 12L1380-36?
  A: All three models share the same 0.3 HP motor, 1/4" collet, composite housing, and rear exhaust configuration. The primary difference is free speed: the 12L1382-36 operates at 20,000 RPM, while the 12L1381-36 is rated at 25,000 RPM and the 12L1380-36 at 30,000 RPM.
• Q: Why choose a 20,000 RPM grinder?
  A: A lower free speed provides greater control for precision deburring, edge blending, and finishing applications where a more measured cutting action is preferred.
• 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 ensure the accessory is rated for at least 20,000 RPM before use.
• Q: What benefit does the rear exhaust provide?
  A: Rear exhaust helps direct discharged air away from the front of the grinder, reducing airflow across the workpiece and improving visibility during precision finishing.
