Dotco 12L1001-36 Inline Grinder | 12-10 Series | 0.3 HP | 34,000 RPM | 1/4" Collet | Composite Housing | Front Exhaust

Built for die work, mold repair, precision deburring, and controlled material removal, the Dotco 12L1001-36 Inline Grinder gives technicians a compact pneumatic grinder with the speed needed for small carbide burrs and mounted wheels. Its 12-10 Series composite body 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 surface control matters more than aggressive stock removal.

This model uses a 1/4" 300 Series collet for common die grinder accessories and is rated for 1/2" carbide burrs and 1" mounted wheels. The front exhaust configuration vents air at the front of the tool, and the lock-off lever helps reduce accidental starts during handling or repositioning. At just 0.8 lb and 6.0" overall length, the 12L1001-36 is well suited for close-control grinding, edge cleanup, weld touch-up, and access-limited finishing tasks.

FAQs:

• Q: What accessories can I use with the Dotco 12L1001-36?
  A: This grinder uses a 1/4" collet and is rated for 1/2" carbide burrs and 1" mounted wheels. Always verify that the accessory shank size matches the collet and that the accessory speed rating meets or exceeds 34,000 RPM.
• Q: What does front exhaust mean on this grinder?
  A: Front exhaust means the exhaust air exits toward the front of the tool instead of through the rear. This configuration may be preferred when a short, compact tool layout is more important than routing exhaust air away through an overhose.
• Q: Is this a good grinder for heavy stock removal?
  A: No. The 12L1001-36 is a compact 0.3 HP inline die grinder for detail grinding, deburring, and finishing. For heavier material removal, choose a higher horsepower die grinder or wheel grinder matched to the abrasive size required.
• Q: What air setup is recommended?
  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 avoid undersized fittings that can restrict airflow.
