Dotco 12L1111-36 Inline Extended Grinder | 12-11 Series | 0.3 HP | 25,000 RPM | 1/4" Collet | Composite Housing | Front Exhaust

Built for deburring, light grinding, and hard-to-reach material removal, the Dotco 12L1111-36 inline extended grinder gives toolroom, fabrication, and repair technicians a compact pneumatic grinder with added reach. This 12-11 Series model combines a 0.3 HP (0.22 kW) motor with 25,000 RPM free speed, giving operators the speed needed for controlled use with compatible carbide burrs, mounted points, and mounted wheels. Its 3" extended housing helps reach inside pockets, ports, cavities, and recessed work areas where a standard inline grinder may not provide enough access.

The 1/4" collet accepts compatible 1/4" shank accessories, while the composite housing keeps the tool manageable during detailed finishing work. A front exhaust configuration means exhaust exits near the tool nose, which can be useful when a rear exhaust or overhose setup is not required. Rated for operation at 90 PSI / 620 kPa, the 12L1111-36 is a practical choice for controlled deburring, blending, and finishing tasks in metalworking, machine shops, automotive repair, and industrial MRO environments.

FAQs:

• Q: What accessories can be used with the Dotco 12L1111-36?
  A: This grinder is listed for use with 1/2" carbide burrs and 1" mounted wheels. Accessories must fit the 1/4" collet and must have a maximum operating speed rating equal to or greater than the tool’s 25,000 RPM free speed.
• Q: What does the 3" extension help with?
  A: The extended housing gives the operator more reach into pockets, ports, recesses, and fixtured parts. It is useful when a standard inline grinder body cannot get the abrasive close enough to the work area.
• Q: Is this a front exhaust or rear exhaust grinder?
  A: The 12L1111-36 is the front exhaust version. Front exhaust means the air exits near the working end of the tool instead of through the rear of the housing.
• Q: What air setup does this grinder require?
  A: Manufacturer data lists performance at 90 PSI / 620 kPa, a 1/4" air inlet size, and a minimum hose I.D. of 1/4" / 4.8 mm. Use clean, regulated, lubricated air and confirm the compressor can support the tool under your duty cycle.
• Q: Does this tool include the collet?
  A: Yes. The listed standard equipment includes the applicable collet and collet wrenches.
