Dotco 12L1100-36 Inline Extended Grinder | 12-11 Series | 0.3 HP | 28,000 RPM | 1/4" Collet | Composite Housing | Front Exhaust

When a standard straight grinder cannot reach deep enough into the work area, the Dotco 12L1100-36 inline extended grinder gives technicians added access for controlled deburring, blending, and light material removal. This 12-11 Series tool combines a compact 0.3 HP / 0.22 kW pneumatic motor with 28,000 RPM free speed, giving operators the speed needed for compatible carbide burrs, mounted points, and mounted wheels in detailed finishing work. The 3" extension helps reach into pockets, ports, fixtures, and recessed components where shorter die grinders may be difficult to position.

The 1/4" collet accepts compatible 1/4" shank accessories, while the composite housing keeps the tool weight to 1.1 lb / 0.50 kg for better control during hand-guided grinding. A front exhaust configuration routes exhaust air near the working end of the tool, making this model a direct match for buyers who need the 3" extended 12-11 Series grinder in the front exhaust configuration rather than the rear exhaust version.

FAQs:

• Q: What is the difference between the Dotco 12L1100-36 and the 12L1180-36?
  A: The 12L1100-36 is the front exhaust version, while the 12L1180-36 is the rear exhaust version. Both are listed in the same 12-11 Series extended grinder table with 28,000 RPM, 1/4" collet size, 3" extension, and composite housing.
• Q: What accessories fit this grinder?
  A: This model uses a 1/4" collet and is listed for 1/2" carbide burrs and 1" mounted wheels. Always confirm the accessory shank size, workpiece compatibility, and RPM rating before use.
• Q: Why choose the 3" extended model instead of a standard inline grinder?
  A: The 3" extension gives extra reach into pockets, ports, cavities, and fixtured parts. It is useful when the abrasive needs to reach farther than the body length of a standard inline grinder allows.
• Q: What air pressure should this tool run at?
