For fast deburring, contour cleanup, and die work with metric-shank accessories, the Dotco 12L1080-36M6 Inline Die Grinder combines 0.3 HP pneumatic output with a 30,000 RPM free speed. That speed range supports efficient material removal with compatible carbide burrs and mounted wheels, while the 6 mm collet gives shops a metric accessory interface for burrs and mounted points that will not fit a standard 1/4" collet.
Part of the Dotco 12-10 Series, this inline grinder uses a compact composite housing to keep the tool light and easy to guide across edges, slots, ports, and small machined details. The rear exhaust configuration directs exhaust air away from the work area and is OH Overhose-ready, meaning an optional overhose setup can be added for additional noise suppression when the application calls for it.

Applications:
- Die and mold maintenance: refining cavities, removing small imperfections, and blending parting lines with compatible metric-shank burrs.
- Machining and CNC support: deburring holes, milled edges, turned parts, and machined slots before inspection or assembly.
- Metal fabrication: cleaning cut edges, dressing weld starts, shaping brackets, and smoothing tight features where larger grinders cannot reach.
- Automotive and motorsport work: port cleanup, casting flash removal, bracket shaping, and small-area grinding in engine, chassis, and restoration projects.
- Maintenance and repair: controlled cleanup of worn parts, keyways, housings, and equipment components during shop or plant service work.
FAQs:
- Q: What is the difference between this 6 mm collet model and a 1/4" collet model?
A: The 6 mm collet accepts metric-shank accessories, while a 1/4" collet accepts inch-size accessories. The two sizes are close but not interchangeable, so match the grinder collet to the burr or mounted wheel shank your shop uses. - Q: Does the 12L1080-36M6 include an overhose?
A: This SKU is a rear exhaust model and is OH Overhose-ready, but the catalog distinguishes OH versions separately. Select the OH model or applicable conversion components if you need an overhose for additional noise suppression. - Q: What accessories can be used with this grinder?
A: The catalog lists abrasive capacity as 1/2" carbide burr and 1" mounted wheel. Accessories must fit the 6 mm collet and have a maximum operating speed equal to or greater than the grinder’s 30,000 RPM free speed. - Q: What air supply does this tool require?
A: The grinder is performance rated at 90 PSI / 620 kPa and requires a minimum 1/4" / 6.4 mm hose I.D. A properly sized filter-regulator-lubricator helps keep the tool supplied with clean, regulated, lubricated air. - Q: Is this the left hand rotation version?
A: No. The 12L1080-36M6 is listed as a rear exhaust 6 mm collet model, not an LH model. Choose an LH-designated SKU only when left hand rotation is specifically required.
