Dotco 12L2002-01 Inline Grinder | 12-20 Series | 0.6 HP | 18,000 RPM | 1/4" Collet | Composite Housing | Front Exhaust

Built for controlled deburring, die grinding, and fine finishing work, the Dotco 12L2002-01 Inline Grinder delivers 0.6 HP of pneumatic power at 18,000 RPM for shops that need a compact straight grinder with enough speed for carbide burrs and mounted wheels. It's 1/4" collet accepts common die grinder accessories, while the front exhaust configuration directs air away from the operator’s hand and toward the work area, which can help keep chips and dust moving during close-detail grinding tasks.

The 12-20 Series composite housing keeps the tool weight to 1.4 lbs., giving operators better control during edge cleanup, weld blending, mold work, and small-area material removal. A lock-off lever throttle helps reduce accidental start-up, and the straight inline body gives the tool a familiar pencil-style feel for guiding carbide burrs into tight corners, ports, castings, and fabricated parts where larger grinders are harder to position.

FAQs:

• Q: What accessories fit the Dotco 12L2002-01?
  A: This model uses a 1/4" collet and is listed for 3/4" carbide burrs and 1-1/2" mounted wheels. Always confirm the accessory shank size, diameter, and maximum RPM before use.
• Q: What does front exhaust mean on this grinder?
  A: Front exhaust means the tool vents air toward the front of the grinder instead of out the rear. This can help move debris away from the cut area, but the best choice depends on whether you prefer air directed forward or away from the workpiece.
• Q: Is this a good grinder for tight spaces?
  A: Yes, the inline body, 6.9" overall length, and 1.4 lb. weight make it useful for close-access deburring and detail grinding. For recessed areas that need extra reach, compare this model with extended die grinder configurations.
• Q: What air setup should be used with this tool?
  A: Cleco rates performance at 90 PSI / 620 kPa and lists a 1/4" minimum hose I.D. Use clean, regulated, lubricated air and avoid undersized hoses or fittings that restrict airflow.
• Q: Can I use cut-off wheels or saw blades on this grinder?
  A: No. This tool is intended for compatible die grinder accessories such as properly rated carbide burrs and mounted wheels. Do not mount saw blades or non-reinforced grinding wheels.
