Dotco 10R9000-08 Precision Turbine Grinder | 10-90 Series | 0.06 HP | 100000 RPM | 1/8" Collet | Steel Housing | Front Exhaust

For inch-shank detail tooling used in precision deburring, fine edge cleanup, and small-feature finishing, the Dotco 10R9000-08 Precision Turbine Grinder delivers very high speed in a compact inline format. It's 100,000 RPM free speed helps small diamond pins cut cleanly without the bulk of a larger die grinder, while the 1/8" collet matches common accessory shanks used in North American toolrooms, mold shops, and fabrication benches. The 0.06 HP turbine motor is intended for light, controlled material removal rather than heavy stock removal, making it a strong fit for detail work where accuracy and surface finish matter.

Part of the 10-90 Series, this front-exhaust turbine grinder uses a roll throttle, which is a rotating sleeve-style throttle that gives the operator controlled start-up and speed handling during close work. The precision spindle and high precision ball bearings support smooth accessory rotation at high speed, while the compact body helps operators reach small contours, machined edges, and intricate workpiece details.

Features:

• Two-stage turbine motor provides high-speed rotation for fine finishing, deburring, and small-detail material removal.
• Roll throttle supports controlled speed engagement when working around edges, holes, contours, and delicate features.
• Front exhaust configuration keeps the tool compact and directs exhaust forward from the inline body.
• High precision ball bearings help maintain smooth operation at elevated spindle speed.
• Precision spindle helps produce a clean finish when paired with a properly rated diamond pin.
• 1/8" collet accepts common inch-shank precision accessories used in toolroom and fabrication environments.
• Standard 10-90 Series equipment includes applicable collet, collet wrenches, 7 ft. / 2.1 m air supply hose, and replaceable cartridge hose filter.
• Dry-air operation required; turbine grinders should not be lubricated through the air line.

Made in USA:

Applications:

• Toolroom and mold work — refining small cavities, edges, slots, and detailed profiles with 1/8" shank accessories.
• Precision machining departments — removing burrs from drilled holes, milled edges, and close-tolerance components after machining.
• Aerospace and component finishing — light cleanup on small parts where high speed and controlled handling are more important than grinding force.
• Metal fabrication benches — cleaning fine details, small weld areas, and tight corners before coating, inspection, or assembly.
• Maintenance and repair work — correcting minor surface imperfections and preparing detailed areas on tools, fixtures, and mechanical parts.

FAQs:

• Q: What is the main difference between the 10R9000-08 and the 10R9000-03?
  A: The 10R9000-08 uses a 1/8" collet, while the 10R9000-03 uses a 3 mm collet. Choose the model that matches the shank size of the diamond pins or other approved accessories you plan to use.
• Q: Is this grinder meant for heavy grinding?
  A: No. This is a high-speed precision turbine grinder for light deburring, finishing, and detail cleanup. For heavier stock removal, use a larger die grinder or wheel grinder with the correct rated abrasive capacity.
• Q: Can I lubricate this tool with standard pneumatic tool oil?
  A: No. Dotco turbine grinders require dry air at 90 PSI maximum and should not be lubricated. Oil in the air stream can reduce turbine performance and shorten tool life.
• Q: What does front exhaust mean?
  A: Front exhaust means air exits near the front of the tool instead of out the rear. This should be considered when working around chips, dust, or delicate surfaces that could be affected by exhaust direction.
• Q: Can a quick-disconnect fitting be installed directly on the grinder?
  A: No. The catalog cautions not to attach a quick-disconnect fitting directly to the tool. Use the supplied hose arrangement and follow the manufacturer’s operating instructions.
