Dotco 12L1081-36 Inline Grinder | 12-10 Series | 0.3 HP | 34,000 RPM | 1/4" Collet | Composite Housing | Rear Exhaust

Built for die work, mold repair, precision deburring, and controlled material removal, the Dotco 12L1081-36 Inline Grinder gives technicians a compact straight-body pneumatic grinder with the speed needed for small carbide burrs and mounted wheels. The 12-10 Series composite housing keeps the tool light in hand, while the 0.3 HP / 0.22 kW motor and 34,000 RPM free speed support fine finishing work where edge control and surface detail matter more than aggressive stock removal.

This model uses a 1/4" 300 Series collet to hold common die grinder accessories with 1/4" shanks, and it is rated for 1/2" carbide burrs and 1" mounted wheels. The rear exhaust configuration directs spent air away from the work area and is Overhose-ready when additional noise suppression is needed. At 0.88 lb and 6.0" overall length, the 12L1081-36 is well suited for access-limited grinding, weld touch-up, burr removal, and detail finishing in fabrication, transportation, welding, and mold service environments.

Applications:

• Die and mold work: Cleaning parting lines, refining cavities, and touching up small areas where a larger grinder would remove too much material.
• Fabrication and welding: Deburring cut edges, blending weld starts and stops, and cleaning tight corners after layout, cutting, or fitting.
• Transportation equipment repair: Detail grinding on brackets, panels, weldments, and small metal components during maintenance or rebuild work.
• General MRO and shop maintenance: Removing burrs, breaking sharp edges, and preparing small surfaces for assembly or touch-up finishing.
• Garage and small-shop use: Controlled grinding with 1/4" shank burrs when the air system, accessory speed rating, and safety requirements match the tool.

FAQs:

• Q: What accessories can I use with the Dotco 12L1081-36?
  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, accessory type, and maximum RPM rating before use.
• Q: What does rear exhaust mean on this inline grinder?
  A: Rear exhaust means spent air exits toward the back of the tool instead of the front. This can help keep exhaust air away from the work area during detailed grinding and finishing.
• Q: What air pressure should this grinder run at?
  A: Dotco rates this tool’s performance at 90 PSI / 620 kPa. Use a properly sized regulator and a minimum 1/4" I.D. air hose to help maintain stable tool speed under load.
• Q: Does the 12L1081-36 include the Overhose?
  A: No. The 12L1081-36 is a rear exhaust model that is Overhose-ready, but the standard equipment listed for this model is the applicable collet and collet wrenches.
• Q: Is this the right grinder for heavy stock removal?
  A: This 0.3 HP inline grinder is better matched to deburring, die work, mold work, and controlled finishing with small accessories. For larger wheels or more aggressive grinding, choose a higher-horsepower die grinder, angle grinder, or wheel grinder rated for the accessory size.
