When you need controlled material removal in a compact straight-body tool, the Dotco 12L1028-36M6 inline die grinder brings 0.3 HP (0.22 kW) output and 20,000 RPM free speed for deburring, mold work, edge cleanup, and small-area finishing. An inline die grinder is a straight rotary grinder used with carbide burrs and mounted wheels, giving the operator a narrow grip and direct approach to the workpiece. The 300 Series collet configuration includes 1/4″ and 6 mm collets, so buyers can run common imperial or metric shank accessories when the accessory rating matches the tool speed.The rear exhaust layout directs spent air away from the front of the tool, helping keep the work area clearer during close-up grinding and deburring. With a composite housing, 0.88 lb weight, and 6.0″ overall length, this Dotco 12-10 Series grinder is sized for toolroom, maintenance, fabrication, and die/mold environments where reach, control, and accessory compatibility matter more than bulk power.Type: Inline Die Grinder | Series: 12-10 Series | Model: 12L1028-36M6 | Power: 0.3 HP / 0.22 kW | Free Speed: 20,000 RPM | Collet Size: 1/4″ and 6 mm | Exhaust: Rear | Abrasive Capacity: 1/2″ carbide burr, 1″ mounted wheel | Housing: Composite | Weight: 0.88 lb | Length: 6.0″ | Air Inlet Size: 1/4″ | Minimum Hose I.D.: 1/4″ / 6.4 mm | Rated Air Pressure: 90 PSI / 620 kPaFeatures:0.3 HP motor output supports controlled deburring, blending, and small-area material removal.20,000 RPM free speed suits compatible carbide burrs and mounted wheels used for general die grinder work.Includes both 1/4″ and 6 mm collets on the -36M6 configuration for imperial and metric shank accessory options.Rated abrasive capacity covers 1/2″ carbide burrs and 1″ mounted wheels.Durable composite housing keeps tool weight low for close-control grinding and finishing tasks.Compact 6.0″ overall length helps the tool reach into tight work areas, cavities, and fixture-adjacent surfaces.Rear exhaust configuration moves discharge air away from the tool nose during detail work.Standard equipped with a lock-off lever to help reduce accidental start risk during handling.Made in USA: Applications:Die and mold work: Cleaning parting lines, blending small contours, and refining mold details with compatible burrs.Machine shops and toolrooms: Removing burrs from machined edges, drilled holes, slots, and fixture components.Metal fabrication: Touch-up grinding, weld-adjacent cleanup, and edge conditioning on brackets, frames, and small assemblies.Industrial maintenance and MRO: Cleaning gasket surfaces, dressing repair parts, and removing sharp edges during equipment service.Automotive and garage repair: Deburring small metal parts, cleaning tight access areas, and shaping repair components when paired with properly rated accessories.FAQs:Q: What collet sizes come with the 12L1028-36M6?A: The -36M6 configuration includes both a 1/4″ collet and a 6 mm collet. A collet is the clamping sleeve that holds the accessory shank, so the accessory shank size must match the installed collet.Q: What accessories can this die grinder run?A: The catalog lists capacity for a 1/2″ carbide burr and a 1″ mounted wheel. Any accessory used on this tool must be rated for at least 20,000 RPM.Q: What does rear exhaust mean on this grinder?A: Rear exhaust routes spent air out the back of the tool instead of the front. This can help keep air discharge away from the grinding point during close-up deburring and finishing.Q: What air setup is required?A: The tool is performance rated at 90 PSI / 620 kPa and lists a 1/4″ minimum hose I.D. Use clean, regulated, lubricated air and avoid undersized hose that can restrict tool speed.Q: Is this a good choice for die and mold work?A: Yes. The 20,000 RPM speed, compact inline body, and burr capacity make it well suited for controlled die/mold work, deburring, and detail grinding when matched with the correct accessory.
