Dotco 10R0401-13 Inline Precision Grinder | 10-04 Series | 0.1 HP | 60,000 RPM | 3 mm Collet | Aluminum Housing | Rear Exhaust

When a large die grinder removes too much material, the Dotco 10R0401-13 gives machinists, fabricators, and finishing technicians a smaller air-powered option for controlled edge cleanup. This 10-04 Series inline precision grinder runs at 60,000 RPM free speed, which is the no-load accessory speed used for small carbide burrs and diamond pins that need high surface speed to cut cleanly. Its 0.1 HP motor is built for fine deburring and light metal removal rather than aggressive grinding, while the 3 mm collet holds compatible 3 mm shank accessories for close-detail work on machined edges, drilled holes, castings, and tight contours.

The aluminum housing keeps the tool compact while providing a metal-bodied feel for frequent shop use. A collet guard helps cover the rotating tool-holding area, and the rear exhaust with 1 ft. overhose routes spent air back from the nose of the grinder so the operator can better see the workpiece. Use the catalog-listed abrasive capacity of 1/4" carbide burr or 1/4" diamond pin as the accessory head capacity, not the shank size; the shank must match the 3 mm collet.

Applications:

• Machine shops and toolrooms — removing small burrs from drilled holes, slots, machined edges, and detail features without switching to a larger die grinder.
• Aerospace and precision fabrication — fine cleanup on aluminum, light metal components, and close-tolerance parts when paired with the correct rated accessory.
• Metal finishing and casting cleanup — refining small contours, parting lines, and hard-to-reach surfaces with carbide burrs or diamond pins.
• Maintenance and MRO benches — touch-up deburring on brackets, fixtures, small housings, and replacement parts during repair work.
• Automotive, performance, and hobby machining — detail work on small fabricated parts, ports, edges, and custom components where a full-size grinder is too large.

FAQs:

• Q: What size accessories fit the Dotco 10R0401-13?
  A: This model uses a 3 mm collet, so the accessory shank must be 3 mm. The catalog’s 1/4" carbide burr and 1/4" diamond pin listing refers to abrasive capacity, not a 1/4" shank.
• Q: Is this grinder for heavy material removal?
  A: No. With a 0.1 HP motor and 60,000 RPM speed, this tool is intended for precision deburring, detail finishing, and small-area metal removal. For heavier stock removal, use a larger die grinder matched to the required burr or wheel size.
• Q: Why does this tool run at 60,000 RPM?
  A: Small burrs and mounted points require high speed to cut efficiently at their smaller diameter. Always confirm the accessory’s maximum operating speed equals or exceeds 60,000 RPM before mounting it.
• Q: What does rear exhaust with overhose mean?
  A: Rear exhaust sends used air out the back of the tool instead of near the workpiece. The 1 ft. overhose helps direct that air away from the immediate grinding area.
• Q: What air setup should I use?
  A: The catalog rates tool performance at 90 PSI and lists a 3/16" minimum hose I.D. for this class of precision grinder. Use clean, regulated, lubricated air and confirm compressor capacity before continuous production use.
