Dotco 10R0401-43 Inline Precision Grinder | 10-04 Series | 0.1 HP | 60,000 RPM | 3 mm Collet | Aluminum Housing | Rear Exhaust

When small edges, slots, and machined details need careful cleanup, the Dotco 10R0401-43 inline precision grinder gives technicians a compact, high-speed tool for controlled deburring and fine metal removal. This 10-04 Series grinder delivers 0.1 HP at 60,000 RPM free speed, giving properly rated miniature carbide burrs and diamond pins the surface speed needed for clean cutting on small features. The 3 mm collet—the clamping sleeve that holds the accessory shank—matches metric precision accessories used in toolroom, mold, die, and detailed finishing work.

The aluminum housing keeps the tool light for hand-guided detail work, while the rear exhaust configuration directs spent air away from the front of the grinder. This SKU is catalog-listed with a 4 ft / 1.2 m overhose, which helps carry exhaust farther from the handpiece and work area than shorter overhose versions in the same series. A roll throttle supports fingertip control during delicate grinding passes, making the 10R0401-43 a practical choice for precision manufacturing, bench repair, and small-part finishing.

Applications:

• Toolroom and mold work — removing small burrs, cleaning parting lines, and refining machined details with compatible 3 mm shank accessories.
• Precision metalworking — finishing slots, holes, small castings, and tight inside corners where a full-size die grinder is too large.
• Industrial maintenance and MRO — correcting small fit-up areas, deburring replacement parts, and cleaning edges around brackets or machined faces.
• Automotive and motorsports bench work — careful casting flash removal, port cleanup, and small-detail finishing with properly rated burrs.
• Fabrication and repair shops — controlled edge cleanup on small components before assembly, inspection, or final finishing.

FAQs:

• Q: What is the main difference between the 10R0401-43 and similar 10-04 Series Dotco grinders?
  A: The 10R0401-43 uses a 3 mm collet and is catalog-listed with a 4 ft / 1.2 m overhose. Other nearby models may use 1/8" or 3/32" collets and shorter overhose lengths, so match the SKU to the accessory shank size and exhaust-routing setup you need.
• Q: Can I use 1/8" accessories in the 3 mm collet?
  A: No. A 3 mm collet is made for 3 mm shank accessories. A 1/8" shank is slightly larger than 3 mm and should only be used with the correct 1/8" collet model.
• Q: What does the 1/4" carbide burr capacity mean?
  A: It refers to the maximum listed burr head size, not the shank size. This grinder uses a 3 mm collet, so the accessory must have a compatible 3 mm shank and a safe speed rating for the tool.
• Q: Why does rear exhaust matter on a precision grinder?
  A: Rear exhaust routes air away from the nose of the tool, helping keep airflow from blowing chips or dust directly across the work point. The overhose also helps carry exhaust farther from the operator’s hand.
• Q: Can a quick-disconnect fitting be mounted directly on this grinder?
  A: No. The catalog notes not to attach a quick-disconnect fitting directly to the tool. Use the correct hose arrangement and follow the manufacturer’s operating instructions.
