Dotco 12S1008-36 Inline Grinder | 12-10 Series | 0.3 HP | 20,000 RPM | 1/4" Collet | Composite Housing | Front Exhaust

Built for controlled deburring, die work, and small-area finishing, the Dotco 12S1008-36 Inline Grinder delivers 0.3 HP of pneumatic power at a lower 20,000 RPM speed for users who want fast material removal with slightly more control than higher-speed 25,000–34,000 RPM models in the same 12-10 Series family. The 1/4" 300 Series collet accepts common carbide burrs and mounted wheels, making this inline grinder a practical choice for metalworking benches, mold repair stations, fabrication shops, and maintenance departments.

The front exhaust layout sends exhaust air forward at the tool head, while the composite housing keeps the grinder compact and easy to position during detail work. With a 6" overall length and 0.88 lb tool weight, the 12S1008-36 is well suited for reaching pockets, edges, contours, and interior surfaces where larger grinders limit visibility or control.

Applications:

• Die and mold work — cleaning up cavities, small slots, and machined detail areas with carbide burrs or mounted points.
• Metal fabrication — removing burrs from cut edges, weld-adjacent areas, brackets, and small fabricated parts.
• Machine shops — breaking sharp edges, blending tool marks, and preparing parts before inspection or assembly.
• Aerospace and composite repair — controlled detail grinding where a compact inline housing helps maintain accuracy.
• Automotive and performance shops — port cleanup, gasket surface preparation, bracket modification, and general bench repair.
• Industrial maintenance and MRO — touching up replacement parts, housings, shafts, and equipment components before reinstallation.

FAQs:

• Q: What is the main difference between the Dotco 12S1008-36 and faster 12-10 Series grinders?
  A: The 12S1008-36 runs at 20,000 RPM, giving it a slower speed than the 25,000, 30,000, and 34,000 RPM versions in the same general family. That lower speed can be useful when the user wants more control with compatible burrs or mounted wheels.
• Q: What size accessories can this grinder use?
  A: This model uses a 1/4" collet and is rated for a 1/2" carbide burr or a 1" mounted wheel. The accessory must be designed for die grinder use and must have a maximum operating speed equal to or greater than 20,000 RPM.
• Q: Is this grinder suitable for tight spaces?
  A: Yes. The inline body, 6" length, and compact composite housing make it useful for pockets, edges, contours, and other detail areas where a larger angle grinder would be difficult to control.
• Q: What air supply setup is required?
  A: The tool is performance rated at 90 PSI / 620 kPa and the catalog specifies a minimum hose I.D. of 1/4" / 6.4 mm. Use clean, regulated, lubricated air to help maintain speed and reduce premature wear.
• Q: Are burrs or mounted wheels included?
  A: No. Standard equipment includes the applicable collet and collet wrenches. Grinding accessories should be selected separately based on material, shape, reach, and required finish.
