Built for high-speed deburring, edge blending, and precision finishing in tight work areas, the Dotco 10LF281-32 Precision Right Angle Die Grinder combines a compact 90-degree head with a 0.4 HP pneumatic motor and 20,000 RPM free speed. Its 1/4"-28 internal threaded collet accepts compatible threaded-shank accessories, while the rear exhaust helps direct discharged air away from the immediate work surface.
Part of the 10LF Series, this rear-exhaust right angle die grinder helps technicians work around fixtures, castings, housings, and assembled components where inline grinders are difficult to position. The 20,000 RPM speed supports faster cutting action with properly rated rotary tooling, making it useful for aerospace work, fabrication, tool and die operations, production deburring, and maintenance finishing.

FAQs:
- Q: What does 1/4"-28i mean?
A: It refers to a 1/4"-28 internal threaded collet connection. Use only matching threaded-shank accessories rated for at least 20,000 RPM. - Q: When should I choose this 20,000 RPM model over a 12,000 RPM version?
A: Choose the 20,000 RPM version when the accessory and material call for faster cutting or quicker deburring. Use the 12,000 RPM version when larger approved accessories or more controlled finishing are the priority. - Q: Why choose rear exhaust?
A: Rear exhaust routes discharged air toward the back of the tool, which can help keep airflow away from the immediate work surface during close detail work. - Q: Can this grinder use standard shank burrs?
A: This model is configured for 1/4"-28 threaded accessories, not standard smooth-shank burrs. Choose a collet model that matches the accessory style used in your shop.
