Built for precision deburring, weld cleanup, and controlled material removal in confined work areas, the Dotco 10LF281-36 right-angle die grinder combines a compact 90-degree head with 0.4 HP / 0.29 kW of pneumatic power and a 20,000 RPM free speed for efficient finishing on metal components. The 1/4" collet accepts compatible carbide burrs and mounted points, while the right angle configuration provides improved access to corners, fixture pockets, and other difficult-to-reach locations where straight grinders are less practical.
As part of the Dotco 10LF Series, this model features a lightweight aluminum housing for improved maneuverability and a rear exhaust configuration that directs exhaust air away from the work surface, helping keep chips and debris clear during detailed grinding operations. Its compact design makes it a dependable choice for fabrication shops, maintenance departments, aerospace manufacturing, transportation equipment production, and general industrial finishing applications.

Applications:
- Metal fabrication: Removing burrs, blending welds, and refining machined edges before assembly or finishing.
- Aerospace manufacturing: Precision deburring and detail finishing on aluminum and other machined components.
- Industrial maintenance: Cleaning corrosion, modifying parts, and performing localized repair work in confined spaces.
- Transportation equipment production: Finishing brackets, weldments, frames, and fabricated assemblies.
- Machine shops and toolrooms: Detail grinding, edge preparation, and component rework using compatible 1/4" shank accessories.
FAQs:
- Q: What advantage does the rear exhaust provide?
A: Rear exhaust directs discharged air away from the work area, helping improve visibility and reducing the chance of blowing chips or dust back onto the finished surface. - Q: What accessories fit the 1/4" collet?
A: The grinder accepts compatible 1/4" shank carbide burrs, mounted points, and similar accessories that are rated for at least the tool's 20,000 RPM operating speed. - Q: Is this intended for grinding wheels?
A: No. This is a right angle die grinder with a collet designed for shank-mounted accessories rather than large grinding wheels or cut-off wheels. - Q: Why choose a 20,000 RPM grinder?
A: A higher free speed supports faster deburring and finishing while maintaining good control with properly rated accessories for precision material removal. - Q: Does this pneumatic grinder require clean, lubricated air?
A: Yes. Using a Filter-Regulator-Lubricator (FRL) helps provide clean, regulated, lubricated air, improving performance while reducing internal wear.
