Dotco 12L1080-36 Inline Grinder | 12-10 Series | 0.3 HP | 30,000 RPM | 1/4" Collet | Composite Housing | Rear Exhaust

When the job calls for controlled deburring, mold touch-up, and fine material removal in tight work areas, the Dotco 12L1080-36 Inline Grinder gives operators a compact straight-body tool with the speed and accessory capacity needed for detail work. This 12-10 Series pneumatic grinder combines a 0.3 HP / 0.22 kW motor with 30,000 RPM free speed, helping maintain fast cutting action with small carbide burrs and mounted wheels while keeping the tool light enough for repetitive bench or production tasks.

The 1/4" 300 Series collet is the clamping sleeve that holds compatible 1/4" shank accessories, making this model a practical choice for common die grinder burrs and mounted points. Its rear exhaust layout sends spent air toward the back of the tool instead of directly onto the work surface, while the composite housing, 0.88 lb tool weight, and 6.0" length support close control when cleaning edges, removing small weld defects, or reaching into confined spaces.

Applications:

• Die and mold maintenance: Cleaning parting lines, refining small contours, and blending minor surface imperfections without stepping up to a larger grinder.
• Metal fabrication: Removing burrs from cut edges, cleaning drilled holes, and touching up small weld areas before finishing or assembly.
• Welding shops: Blending weld starts, stops, and tight corners where controlled accessory contact is more important than heavy stock removal.
• Transportation and equipment repair: Detail grinding around brackets, panels, and machined parts during maintenance, rebuild, or fit-up work.
• General MRO and toolroom use: Breaking sharp edges, cleaning small parts, and preparing localized surfaces for inspection, coating, or assembly.

FAQs:

• Q: What accessories fit the Dotco 12L1080-36?
  A: This grinder uses a 1/4" collet and is rated for 1/2" carbide burrs and 1" mounted wheels. Always confirm the accessory shank size and maximum RPM rating before installing it on the tool.
• Q: What does free speed mean?
  A: Free speed is the tool’s RPM with no accessory load applied. The 30,000 RPM rating helps buyers match the grinder to accessories that are safely rated at or above the tool speed.
• Q: Is this model front exhaust or rear exhaust?
  A: The 12L1080-36 is a rear exhaust inline grinder. Rear exhaust routes air out the back of the tool, which can help keep air blast away from the immediate grinding area.
• Q: What air setup should be used with this grinder?
  A: The tool is rated at 90 PSI / 620 kPa and requires a minimum 1/4" / 6.4 mm I.D. air hose. A properly adjusted regulator and clean, lubricated air supply help maintain speed and reduce premature wear.
• Q: Is this grinder suited for large grinding wheels?
  A: No. This model is intended for small carbide burrs and mounted wheels within the manufacturer’s listed abrasive capacity. For larger wheels or more aggressive stock removal, choose a grinder specifically rated for that wheel size and speed.
