When production deburring or edge cleanup calls for a compact inline grinder with higher working speed, the Dotco 12L2500-01M6 inline die grinder delivers 0.9 HP of pneumatic power with 23,000 RPM free speed for efficient material removal on metal, composite, and fabricated components. Its 6mm collet accepts compatible metric-shank carbide burrs and mounted points, while the front exhaust directs air toward the working end for applications where rear venting is not preferred.Part of the Dotco 12-25 Series, this inline die grinder is suited for burr removal, weld cleanup, casting finishing, part blending, and general shop grinding, where a straight tool body gives better control along edges, bores, fixtures, and narrow work areas. The 23,000 RPM speed range supports fast cutting action with properly rated accessories, making it a practical choice for fabrication, aerospace, automotive, and MRO teams that need a compact grinder with strong power-to-size performance.Type: Inline Die Grinder | Series: 12-25 Series | Model: 12L2500-01M6 | Collet Size: 6mm | Power: 0.9 HP / 0.67 kW | Free Speed: 23,000 RPM | Exhaust: Front | Housing Type: Composite | Air Pressure: 90 PSI / 620 kPa | Air Inlet: 1/4″ | Minimum Hose I.D.: 5/16″ / 7.9 mmFeatures:0.9 HP motor provides strong output for deburring, blending, finishing, and controlled material removal.23,000 RPM free speed supports fast cutting with compatible carbide burrs and mounted abrasive accessories.6mm collet configuration fits metric-shank accessories used in production grinding and finishing work.Front exhaust configuration vents air near the working end for applications where rear exhaust routing is not required.Inline body style helps operators maintain direct control when working along edges, holes, castings, and fabricated parts.Composite housing helps reduce tool weight during repeated grinding and finishing operations.Compact 12-25 Series design supports access into fixtures, assemblies, and confined work areas.Made in USA: Applications:Metal fabrication removing burrs, softening sharp edges, and blending weld areas before finishing.Aerospace and composite shops controlled edge cleanup, trimming support work, and detail finishing on precision components.Automotive and fleet service gasket surface prep, port cleanup, bracket modification, and small-area grinding.Foundry and casting cleanup removing flash, parting lines, and small surface defects with compatible burrs.Industrial maintenance and repair cleaning repaired machine parts, fitting components, and preparing surfaces for reassembly.FAQs:Q: What does the 6mm collet size mean?A: The collet holds accessories with a 6mm shank. Use only burrs, mounted points, or other accessories that match the collet size and are rated for the grinders speed.Q: Is 23,000 RPM suitable for carbide burrs?A: Yes, this speed range is commonly used for die grinding with compatible carbide burrs. Always verify that the burrs maximum operating speed equals or exceeds 23,000 RPM.Q: What is the difference between front exhaust and rear exhaust?A: Front exhaust vents air near the working end of the tool, while rear exhaust directs air away from the work area through the back of the grinder. The better choice depends on your workstation, part geometry, and air-routing preference.Q: Can this grinder be used for weld cleanup?A: Yes, when paired with the correct burr or mounted abrasive, it can be used for weld blending, edge cleanup, and small-area surface preparation.Q: What air setup should be used with this tool?A: Use clean, regulated air at the manufacturers specified 90 PSI and a minimum 5/16″ hose I.D. to help maintain tool speed under load..spec-accordion{width:100%;max-width:1200px;margin:1em
