Dotco 10L2081-01 Inline Grinder | 10-20 Series | 0.6 HP | 20,000 RPM | 1/4" Collet | Aluminum Housing | Rear Exhaust

When the job calls for controlled deburring, die work, and small-area material removal, the Dotco 10L2081-01 Inline Grinder delivers 0.6 HP of pneumatic power in a straight, compact body for steady hand placement around edges, ports, fixtures, and weld prep areas. It's 20,000 RPM free speed supports fast cutting with properly rated carbide burrs and mounted wheels, while the 1/4" 200 Series collet fits common shank-mounted abrasives used for blending, shaping, and burr removal. The aluminum housing keeps the tool lightweight for repeated use, and the rear exhaust directs spent air away from the work area for cleaner handling during close-detail grinding.

The 10L2081-01 uses a lock-off lever throttle, which requires a deliberate lever action to help reduce accidental start-up. Rear exhaust models are OH Overhose Ready, meaning the tool can be paired with an overhose setup for additional exhaust routing and noise suppression when shop conditions call for it. This inline die grinder is suited to die and mold work, fabrication cleanup, transportation repair, welding prep, and general metalworking where a straight grinder body provides better access than a bulkier angle-head tool.

Applications:

• Die and mold work: Cleaning parting lines, opening small passages, blending tool marks, and refining localized surfaces with carbide burrs.
• Metal fabrication: Deburring drilled holes, easing sharp edges, cleaning small weld areas, and preparing metal surfaces for follow-up finishing.
• Transportation and fleet repair: Removing burrs and light material from brackets, castings, housings, and repair components where a straight grinder gives better reach.
• Welding and repair shops: Touch-up grinding around weld toes, fixtures, tabs, and tight corners before inspection, coating, or final assembly.
• Well-equipped garage and restoration work: Shaping small metal parts, cleaning castings, and trimming minor imperfections when paired with a properly sized air system.

FAQs:

• Q: What accessories fit the Dotco 10L2081-01?
  A: This model uses a 1/4" 200 Series collet and is rated for 3/4" carbide burrs and 1-1/2" mounted wheels. Always confirm the accessory shank size and maximum operating speed before mounting.
• Q: What does rear exhaust mean on this inline grinder?
  A: Rear exhaust routes spent air out the back of the tool instead of toward the workpiece. This can help keep chips, dust, and grinding debris from being blown directly across the surface you are finishing.
• Q: What air setup is required?
  A: Manufacturer data rates the tool at 90 PSI / 620 kPa and lists a minimum hose I.D. of 5/16" / 7.9 mm. Use clean, regulated, lubricated air and a hose setup that does not restrict flow during sustained grinding.
• Q: Is this grinder better for burrs or mounted wheels?
  A: It can be used with both, provided the accessory matches the collet and speed requirements. Carbide burrs are commonly used for shaping and deburring, while mounted wheels are used for small-area grinding and blending.
• Q: Does the tool include a collet and wrenches?
  A: Yes. Standard equipment for this grinder family includes the applicable collet and collet wrenches.
