Built for controlled material removal, sanding, deburring, and finishing work, the Dotco 12L2218-36 Right Angle Grinder combines 0.6 HP output with a fast 18,000 RPM free speed for small-disc abrasive work where access and tool control matter. Its right angle head helps reach tight or angled surfaces that inline grinders cannot comfortably access, while the 1/4" collet accepts compatible mounted accessories for surface prep, blending, and edge work.
Part of the 12-22 Series, this rear-exhaust Dotco grinder uses a composite housing to keep tool weight manageable during repetitive shop or production use. Rear exhaust directs air away from the work area, helping reduce dust disturbance when grinding, sanding, or polishing metal, composite, and fabricated components.

FAQs:
- Q: What accessories fit the Dotco 12L2218-36?
A: This tool uses a 1/4" collet and is listed with a 3" sanding/polishing disc abrasive capacity. Always confirm the accessory shank, diameter, and maximum RPM before use. - Q: What does rear exhaust mean?
A: Rear exhaust routes spent air out the back of the tool instead of toward the work surface, helping reduce debris disturbance during sanding, grinding, or finishing. - Q: Is this grinder suited for tight spaces?
A: Yes. The right angle layout and short angle head help the tool reach areas where a straight inline grinder may be awkward or blocked. - Q: Can I use any abrasive accessory rated for 1/4" shanks?
A: No. The shank must fit, but the accessory must also be appropriate for the tool type, disc capacity, and 18,000 RPM operating speed.
