Dotco 12L1000-36 Inline Grinder | 12-10 Series | 0.3 HP | 30,000 RPM | 1/4" Collet | Composite Housing | Front Exhaust

When controlled burr work matters more than aggressive stock removal, the Dotco 12L1000-36 Inline Grinder gives toolroom, fabrication, and maintenance users a compact pneumatic option for detailed grinding and deburring. Its 12-10 Series composite housing keeps the tool light and manageable, while the 0.3 HP / 0.22 kW motor and 30,000 RPM free speed provide the speed range needed for properly rated carbide burrs, rotary files, and mounted points.

The 1/4" 300 Series collet accepts common die grinder accessories, and the tool is rated for 1/2" carbide burrs and 1" mounted wheels. Its inline body helps the operator guide the accessory into small openings, castings, dies, molds, and fixture details, while the front exhaust layout keeps the tool short and direct for close-control work. A standard lock-off lever helps reduce accidental throttle activation during handling or repositioning.

FAQs:

• Q: What is the Dotco 12L1000-36 used for?
  A: This inline grinder is used for die grinding, mold work, deburring, light blending, and small-area material removal. It is best matched with compatible carbide burrs, rotary files, and mounted wheels rather than large grinding wheels.
• Q: What size accessories fit this grinder?
  A: The tool uses a 1/4" 300 Series collet and is rated for 1/2" carbide burrs and 1" mounted wheels. Always confirm both shank size and maximum accessory RPM before installation.
• Q: What does front exhaust mean?
  A: Front exhaust means the exhaust air exits toward the front of the tool. This configuration keeps the tool compact and direct, which can be useful when working inside fixtures, cavities, and other access-limited areas.
• Q: Is this grinder suitable for heavy material removal?
  A: The 12L1000-36 is a 0.3 HP detail grinder, so it is better suited to controlled finishing and deburring than aggressive grinding. For larger wheels or faster stock removal, select a higher-horsepower grinder matched to the abrasive size required.
• Q: What air supply should be used?
  A: The tool is performance rated at 90 PSI / 620 kPa and requires a minimum 1/4" hose I.D. Use clean, regulated, lubricated air and properly sized fittings to avoid restricting tool performance.
