Dotco 10R0400-18 Inline Precision Grinder | 10-04 Series | 0.1 HP | 60,000 RPM | 1/8" Collet | Aluminum Housing | Rear Exhaust

Built for precision deburring, fine edge cleanup, and controlled metal removal, the Dotco 10R0400-18 inline precision grinder delivers 0.1 HP in a compact pencil-style air tool for detail work where larger die grinders are too bulky. It's 60,000 RPM free speed helps small carbide burrs and diamond pins cut cleanly on tight features, while the 1/8" collet accepts compatible precision-shank accessories for controlled finishing on small parts, mold details, and machined edges.

Part of the 10-04 Series, this rear exhaust model uses a lightweight aluminum housing and roll throttle to support fingertip control during high-speed grinding. The catalog-rated abrasive capacity is 1/4" carbide burr or 1/4" diamond pin, making it a practical choice for toolrooms, metalworking benches, maintenance shops, and precision manufacturing environments that need accurate material removal without the size of a full die grinder.

FAQs:

• Q: What is the Dotco 10R0400-18 used for?
  A: This inline precision grinder is used for fine deburring, detail grinding, and light metal removal with small carbide burrs or diamond pins. Its pencil-style body is useful when the work area is too tight for a larger die grinder.
• Q: Can I use 1/4" shank burrs with this grinder?
  A: No. This model has a 1/8" collet. The 1/4" abrasive capacity refers to the rated burr or diamond pin size, not the shank size.
• Q: What does rear exhaust mean on this tool?
  A: Rear exhaust routes air out the back of the grinder instead of toward the front working point. On this model, the 1 ft / 0.3 m overhose helps move exhaust away from the immediate grinding area.
• Q: What accessories are safe to use at 60,000 RPM?
  A: Use only abrasive accessories with a maximum operating speed equal to or greater than 60,000 RPM. Always confirm the accessory rating before mounting it in the collet.
• Q: Should a quick-disconnect fitting be attached directly to the tool?
  A: No. The catalog notes not to attach a quick-disconnect fitting directly to the tool. Use the proper hose setup for the grinder and follow the manufacturer’s operating instructions.
