Dotco 10R0401-18 Inline Precision Grinder | 10-04 Series | 0.1 HP | 60,000 RPM | 1/8" Collet | Aluminum Housing | Rear Exhaust

When small burrs, mold details, drilled holes, or machined edges need controlled cleanup, the Dotco 10R0401-18 inline precision grinder gives technicians a compact pneumatic tool for fine material removal. This 10-04 Series grinder uses a 0.1 HP motor and 60,000 RPM free speed to run small carbide burrs and diamond pins efficiently, while the 1/8" collet accepts common precision grinding accessories used for deburring, blending, and finishing tight features.

The inline body keeps the tool pencil-like in the hand for detailed control, and the aluminum housing keeps tool weight low for bench work, fixture work, and extended touch-up tasks. Rear exhaust routes air away from the work area through the overhose, helping reduce air blast around fine chips, dust, and small abrasive contact points.

Features:

• High precision ball bearings support smooth spindle operation for detailed deburring and finishing work.
• 60,000 RPM free speed is suited to small carbide burrs and diamond pins where surface control matters more than heavy stock removal.
• 1/8" collet holds common precision grinding accessories used in aerospace, mold work, machining, and fabrication touch-up.
• Inline configuration gives the tool a pencil-style grip for controlled movement around small openings, edges, and contours.
• Compact aluminum housing helps reduce hand fatigue during bench work and repetitive finishing operations.
• Rear exhaust with 1 ft overhose directs exhaust air away from the immediate grinding point.
• Roll throttle allows the operator to bring the tool into the cut with controlled speed response.

Applications:

• Aerospace manufacturing and repair — deburring drilled holes, trimming small composite or metal edges, and blending precision features.
• Machine shops and toolrooms — cleaning machined edges, removing light burrs, and refining slots, ports, and mold details.
• Metal fabrication — touch-up grinding on small weld areas, brackets, tabs, and hard-to-reach corners.
• Automotive, racing, and restoration work — port cleanup, fine casting flash removal, and careful finishing on small components.
• Maintenance and repair benches — controlled material removal where a full-size die grinder would be too large or aggressive.

FAQs:

• Q: What accessories fit the Dotco 10R0401-18?
  A: This model uses a 1/8" collet and is rated for 1/4" carbide burrs and 1/4" diamond pins. Always verify that the accessory shank matches the collet and that the accessory speed rating is safe for 60,000 RPM operation.
• Q: Is this the same as a standard 1/4" die grinder?
  A: No. This is a precision pencil-style grinder with a 1/8" collet and very high free speed. It is better for fine deburring and small detail work, while a 1/4" die grinder is generally used for heavier material removal.
• Q: What does rear exhaust mean on this grinder?
  A: Rear exhaust routes air away from the front of the tool instead of discharging it directly near the burr or pin. That helps keep the work area more controlled during fine finishing tasks.
• Q: What air setup should be used with this pneumatic grinder?
  A: Dotco performance ratings are based on operation at 90 PSI. Use clean, regulated air with the correct 1/8" NPT connection and follow the manufacturer’s lubrication and air preparation guidance.
