Dotco 10R0401-16 Inline Precision Grinder | 10-04 Series | 0.1 HP | 60,000 RPM | 3/32" Collet | Aluminum Housing | Rear Exhaust

For fine deburring, contour cleanup, and controlled metal removal in tight features, the Dotco 10R0401-16 inline precision grinder gives operators a compact pneumatic tool built around speed and fingertip control. Its 10-04 Series configuration combines a 0.1 HP motor with 60,000 RPM free speed, making it well-suited for small abrasive contact points where a standard die grinder would be too bulky or aggressive.

The 3/32" collet supports smaller-shank precision accessories used for detail work, while the aluminum housing keeps the grinder light and maneuverable at the bench, fixture, or repair station. Rear exhaust directs air away from the front of the tool, helping keep chips and abrasive dust from being blown directly across the workpiece during delicate finishing operations.

Applications:

• Aerospace and composite shops — trimming small edges, deburring drilled holes, and refining detailed contours after machining or layup.
• Toolrooms and mold repair — cleaning parting lines, slots, inserts, and other fine features that require controlled hand guidance.
• Machining and metalworking — removing light burrs from milled pockets, ports, threads, and small production parts.
• Fabrication benches — finishing brackets, tabs, tack-weld cleanup, and small hard-to-reach areas before assembly or coating.
• Automotive and restoration work — fine casting cleanup, port touch-up, and careful material removal on small components.

FAQs:

• Q: What is the main difference between the 10R0401-16 and a 1/8" collet model?
  A: The 10R0401-16 uses a 3/32" collet, so it is intended for accessories with a 3/32" shank. A 1/8" collet model is for 1/8" shank accessories; the two sizes are not interchangeable without the correct collet setup.
• Q: What type of work is this grinder best suited for?
  A: This is a precision grinder for light deburring, detail finishing, and controlled metal removal. It is not a substitute for a larger 1/4" die grinder when the job requires heavier stock removal.
• Q: Why does the grinder run at 60,000 RPM?
  A: Small-diameter burrs and pins need higher rotational speed to cut effectively at the contact point. The high free speed helps maintain clean cutting action on small features when used with properly rated accessories.
• Q: How does rear exhaust help during fine grinding?
  A: Rear exhaust sends air away from the front of the tool, reducing direct air blast around the burr or pin. That can make it easier to see and control the work area during detailed deburring.
