Dotco 12R0410-13 Inline Precision Grinder | 12-04 Series | 0.1 HP | 60,000 RPM | 3 mm Collet | Composite Housing | Rear Exhaust

Built for close-control deburring, fine metal removal, and small-part finishing, the Dotco 12R0410-13 Inline Precision Grinder gives toolrooms and production benches a compact pneumatic grinder for work that is too delicate for larger die grinders. The 12-04 Series body pairs 0.1 hp (0.074 kW) output with 60,000 RPM free speed, meaning the tool runs fast enough for small carbide burrs and diamond pins used to clean edges, refine details, and reach narrow profiles. Its 3 mm collet (the clamping sleeve that holds the accessory shank) supports metric-shank finishing accessories, while the rear exhaust helps direct spent air away from the work surface.

With a composite housing, inline configuration, and roll throttle control, the 12R0410-13 is suited for operators who need a pencil-style grinder that can be guided with fingertip accuracy. The collet guard configuration adds coverage around the nose of the tool, and the supplied air hose and overhose help keep the setup clean at the bench or fixture. Use this grinder for precision deburring and controlled metal removal, not aggressive stock removal or wheel grinding.

Applications:

• Toolroom and machine shop finishing — deburring small machined parts, cleaning drilled holes, and refining tight edges after machining.
• Die and mold work — using carbide burrs or diamond pins to touch up cavities, parting lines, and narrow profiles where larger grinders are difficult to control.
• Metal fabrication and production benches — removing small burrs, tabs, and raised edges before assembly, inspection, or final finishing.
• Maintenance and repair departments — cleaning minor defects on metal parts, brackets, fixtures, and service components without stepping up to a larger die grinder.
• Advanced home shop and hobby machining — detail deburring on small metal projects when a properly supplied pneumatic setup is available.

FAQs:

• Q: What accessory shank size fits the Dotco 12R0410-13?
  A: This model uses a 3 mm collet, so accessories must have a compatible 3 mm shank. Do not assume 1/8" accessories will fit unless the correct collet is installed.
• Q: What type of work is this precision grinder best suited for?
  A: It is best used for fine deburring and controlled metal removal with small burrs or diamond pins. For heavy stock removal, weld grinding, or large mounted wheels, select a larger die grinder or wheel grinder with the correct capacity.
• Q: What does rear exhaust mean on this grinder?
  A: Rear exhaust means discharged air exits toward the back of the tool instead of the front. On detail work, this can help keep exhaust away from the cutting point and improve visibility around small features.
• Q: Can I use any burr or abrasive with this 60,000 RPM tool?
  A: No. The maximum operating speed of the accessory must equal or exceed 60,000 RPM, and the accessory must match the tool’s collet and abrasive capacity. Always follow the accessory manufacturer’s mounting and overhang limits.
