Built for controlled deburring, edge blending, and detail grinding, the Dotco 12L1082-36M6 inline die grinder delivers 0.3 HP output with a fast 25,000 RPM free speed for removing burrs, refining machined edges, and shaping small surfaces with compatible rotary accessories. An inline die grinder is a straight-body pneumatic grinder used with carbide burrs and mounted wheels, giving the operator a direct approach to the workpiece and better control in narrow access areas.This 12-10 Series model uses a 6 mm collet for metric-shank accessories and a rear exhaust configuration that routes spent air away from the tool nose during close-up grinding. Its compact 6″ length, composite housing, and 90 PSI operating rating make it a practical choice for die/mold work, fabrication cleanup, maintenance, repair, and general shop deburring where speed, access, and accessory fit matter.Type: Inline Die Grinder | Series: 12-10 Series | Model: 12L1082-36M6 | Grip Type: Inline | Collet Size: 6 mm | Power: 0.3 HP / 0.22 kW | Free Speed: 25,000 RPM | Abrasive Capacity: 1/2″ Carbide Burr, 1″ Mounted Wheel | Housing Type: Composite | Length: 6″ | Air Inlet: 1/4″ NPT | Exhaust: Rear | Air Pressure: 90 PSI / 620 kPa | Minimum Hose I.D.: 1/4″ / 6.4 mmFeatures:0.3 HP motor output supports routine material removal, deburring, and small-area surface cleanup.25,000 RPM free speed provides fast cutting action with properly rated carbide burrs and mounted wheels.6 mm collet accepts metric-shank rotary accessories commonly used in precision grinding and finishing work.Rated abrasive capacity includes 1/2″ carbide burrs and 1″ mounted wheels.Durable composite housing helps keep the tool light and manageable during detail work.Compact inline body gives the operator direct control when working around fixtures, cavities, and tight edges.Rear exhaust helps direct air discharge away from the grinding point and operators forward line of sight.Standard equipped with lock-off lever to help reduce accidental start risk during handling.Made in USA: Applications:Die and mold work: Blending contours, cleaning parting lines, and refining detail areas with compatible burrs.Machine shops and toolrooms: Removing burrs from drilled holes, milled edges, slots, and fixture components.Metal fabrication: Touch-up grinding, edge conditioning, and weld-adjacent cleanup on small steel or aluminum parts.Industrial maintenance and MRO: Dressing repair parts, cleaning tight surfaces, and removing sharp edges during equipment service.Automotive and garage repair: Deburring brackets, cleaning small metal components, and shaping repair areas with speed-rated accessories.FAQs:Q: What does the 6 mm collet do?A: The collet is the clamping sleeve that holds the accessory shank. This model is configured for 6 mm shank accessories, so confirm the burr or mounted wheel shank size before ordering consumables.Q: What accessories can be used with the 12L1082-36M6?A: The listed abrasive capacity is 1/2″ carbide burr and 1″ mounted wheel. Any accessory used on this grinder must be rated at or above the tools 25,000 RPM free speed.Q: How is this model different from a slower 20,000 RPM die grinder?A: The 25,000 RPM speed gives this model faster accessory surface speed for compatible burrs and mounted points. Slower models may be preferred for certain accessories or materials, so always match the grinder speed to the abrasive manufacturers rating.Q: Why choose rear exhaust?A: Rear exhaust routes spent air out the back of the tool instead of toward the workpiece. This is useful when deburring small parts or working close to a surface where front exhaust could disturb chips or debris.Q: What air supply setup does this grinder require?A: The tool is performance rated at 90 PSI / 620 kPa and calls for a 1/4″ minimum hose I.D. Use clean, regulated, lubricated air to help maintain speed and reduce unnecessary wear. .spec-accordion{width:100%;max-width:1200px;margin:1em
