Dotco 10L1112-36 Inline Extended Grinder | 10-11 Series | 0.3 HP | 25,000 RPM | 1/4" Collet | Aluminium Housing | Front Exhaust

Built for controlled material removal in recessed and hard-to-reach areas, the Dotco 10L1112-36 Inline Extended Grinder combines a slim inline layout with a 5" extended housing for access into molds, fixtures, castings, and component pockets. Its 0.3 HP pneumatic motor and 25,000 RPM free speed provide the speed needed for deburring, blending, and light grinding with properly rated carbide burrs and mounted wheels, while the 1/4" 300 Series collet accepts common industrial shank-mounted accessories.

The front exhaust configuration routes exhaust air forward, helping keep the rear hose connection area more manageable during bench, fixture, and detail work. With a lightweight aluminum housing and extended inline reach, the 10L1112-36 is well suited for aerospace, fabrication, metalworking, toolroom, automotive repair, and maintenance applications where access and control matter as much as speed.

Applications:

• Die and mold maintenance — reaching into pockets, contours, and recessed surfaces for burr removal and light grinding.
• Aerospace and composite work — trimming, edge cleanup, and detail finishing where compact tool control is important.
• Metal fabrication — removing small burrs, blending localized surface marks, and cleaning up machined edges.
• Toolroom and fixture repair — working around jigs, tooling, and fixture details with extended inline access.
• Automotive and general repair — casting cleanup, gasket surface preparation, and shank-mounted abrasive work when accessory ratings match the tool speed.

FAQs:

• Q: What is the main benefit of the extended housing?
  A: The 5" extended housing gives the operator additional reach into recessed or obstructed areas where a standard-length inline die grinder may be difficult to position.
• Q: What size accessories does the Dotco 10L1112-36 accept?
  A: This grinder uses a 1/4" 300 Series collet for compatible shank-mounted burrs and mounted wheels. Always confirm accessory shank size and RPM rating before use.
• Q: Can I use any 1/4" shank burr with this grinder?
  A: Only use accessories that fit correctly and have a maximum operating speed equal to or greater than the grinder’s 25,000 RPM free speed.
• Q: What does front exhaust mean?
  A: Front exhaust routes air toward the front of the tool instead of out the rear, which can help manage airflow around the operator’s hand and air hose connection.
• Q: What air supply setup should be used?
  A: Use clean, regulated air at the catalog-rated operating pressure of 90 PSI / 620 kPa, with at least a 1/4" / 6.4 mm minimum hose I.D.
