Dotco 12LF280-36 Right Angle Grinder | 12LF Series | 0.4 HP | 12,000 RPM | 1/4" Collet | Composite Housing | Rear Exhaust

Built for controlled grinding, deburring, and finishing in confined work areas, the Dotco 12LF280-36 Right Angle Grinder combines a 0.4 HP pneumatic motor with a 12,000 RPM free speed to provide smooth, predictable material removal on metal, composites, and fabricated components. The 1/4" collet securely accepts industry-standard carbide burrs and mounted points, while the rear exhaust directs discharged air away from the operator and work surface for improved comfort during extended operation. Its lightweight composite housing helps reduce fatigue without compromising the durability expected in demanding production environments.

As part of the 12LF Series, this right angle grinder is well suited for applications where a straight grinder cannot easily reach. The compact 90-degree head provides improved maneuverability around fixtures, inside weldments, and other restricted spaces, making it an excellent choice for aerospace manufacturing, metal fabrication, industrial maintenance, and precision finishing operations.

FAQs:

• Q: What accessories are compatible with the 1/4" collet?
  A: The grinder accepts standard 1/4-inch shank carbide burrs, mounted points, and other compatible rotary accessories designed for pneumatic grinders.
• Q: Why would I choose a 12,000 RPM grinder instead of a higher-speed model?
  A: A 12,000 RPM model offers greater control during heavier deburring, edge blending, and applications where slower accessory speed provides improved precision.
• Q: What are the advantages of a rear exhaust configuration?
  A: Rear exhaust helps move discharged air away from the work area and operator while allowing compatibility with overhose exhaust systems.
• Q: What air pressure should this grinder be operated at?
  A: The tool is designed to deliver rated performance using clean, dry compressed air at 90 PSI with the recommended hose size.
