Built for fast deburring, blending, and detail grinding in restricted spaces, the Dotco 12LF281-36 Right Angle Grinder pairs a compact 90-degree head with a 0.4 HP pneumatic motor and 20,000 RPM free speed for controlled material removal with carbide burrs and mounted points. Its 1/4" collet accepts common shank-mounted accessories, while the rear exhaust routes discharged air away from the work surface and is overhose ready for applications where additional exhaust control is preferred.
The 12LF Series composite housing keeps the tool light in hand without giving up the access advantages of a right-angle grinder. This model is well suited for aerospace finishing, metal fabrication, mold work, general MRO, and production deburring where a straight die grinder cannot reach the work comfortably.

FAQs:
- Q: What does the 20,000 RPM speed mean for accessory selection?
A: Any burr, mounted point, or abrasive accessory used with this grinder must be rated at or above 20,000 RPM. - Q: What accessories fit the 1/4" collet?
A: This model accepts compatible 1/4" shank carbide burrs, mounted points, and other rotary accessories made for right-angle pneumatic grinders. - Q: Why choose rear exhaust instead of front exhaust?
A: Rear exhaust helps route air away from the work area and can be useful when grinding dust or chips need to stay forward of the operator. - Q: Is this a wheel grinder or a collet grinder?
A: This is a collet-style right angle grinder for shank-mounted accessories, not a large wheel grinder.
