Dotco 12L1101-36 Inline Extended Grinder | 12-11 Series | 0.3 HP | 28,000 RPM | 1/4" Collet | Composite Housing | Front Exhaust

When you need extended reach for controlled material removal, the Dotco 12L1101-36 Inline Extended Grinder gives fabricators, mechanics, and toolroom technicians a compact pneumatic grinder with a 5" extension for accessing recesses, ports, molds, casting cavities, and hard-to-reach edges. Its 0.3 HP / 0.22 kW motor and 28,000 RPM free speed help drive fast deburring and blending with properly rated carbide burrs, mounted points, and mounted wheels.

Part of the Dotco 12-11 Series, this inline extended die grinder uses a 1/4" 300 Series collet for common industrial grinding accessories and a front exhaust configuration that routes exhaust air at the front of the tool. The composite housing keeps the tool weight to 1.3 lbs / 0.59 kg, while multiple industrial bearings support low vibration and balance during detailed material removal work.

Applications:

• Metal fabrication and welding shops — deburring cut edges, blending weld details, and cleaning tight metal surfaces with carbide burrs or mounted points.
• Toolroom and mold work — reaching into pockets, cavities, and internal contours where a standard-length die grinder may not provide enough access.
• Transportation and fleet maintenance — removing burrs, corrosion, and small surface defects from brackets, castings, and repair areas.
• Shipbuilding and structural repair — detail grinding around seams, access holes, and tight weld zones where controlled reach matters.
• Automotive and garage repair — port cleanup, gasket surface preparation, and general deburring when matched with the correct rated accessory.

FAQs:

• Q: What accessories can be used with the Dotco 12L1101-36?
  A: This grinder is intended for carbide burrs, mounted points, and mounted wheels that fit the 1/4" collet. The listed abrasive capacity is 1/2" carbide burr or 1" mounted wheel.
• Q: Why choose an extended inline grinder instead of a standard die grinder?
  A: The 5" extension helps the operator reach into deeper cavities, ports, and tight work areas while keeping the inline body style familiar and controllable.
• Q: Is this a front exhaust or rear exhaust model?
  A: The 12L1101-36 is a front exhaust model. Rear exhaust versions are separate models and should be selected when exhaust routing away from the workpiece is preferred.
• Q: What does the 28,000 RPM rating mean for accessory selection?
  A: Any burr, mounted point, or mounted wheel used on this tool must have a maximum operating speed that equals or exceeds 28,000 RPM. Never use an accessory below the tool speed rating.
• Q: Does this pneumatic grinder need an FRL?
  A: Yes. A properly sized Filter-Regulator-Lubricator helps supply clean, regulated, lubricated air, which can improve tool performance and reduce avoidable wear.
