Dotco 12L1080-36M6OH Inline Die Grinder | 12-10 Series | 0.3 HP | 30000 RPM | 6mm Collet | Rear Exhaust

Built for controlled deburring, edge blending, and small-area material removal, the Dotco 12L1080-36M6OH Inline Die Grinder gives technicians a straight, on-axis tool format for working with compatible rotary burrs, mounted points, and abrasive accessories. Part of the 12-10 Series, this air-powered grinder combines a 0.3 HP motor with 30,000 RPM free speed, meaning no-load rotational speed, for fast cutting action on smaller accessories. The 6 mm collet, the accessory-holding chuck, supports metric-shank tooling, while the rear exhaust helps route spent air away from the work area and the operator’s hands.

The inline body style is well suited for bench work, fixture work, and hand finishing where the accessory needs to stay aligned with the tool body. Use this Dotco grinder for spot grinding, part cleanup, light weld blending, casting cleanup, and finishing operations where a full-size angle grinder would be too large or too aggressive.

FAQs:

• Q: What accessories fit the Dotco 12L1080-36M6OH?
  A: This model uses a 6 mm collet, so it should be paired with compatible 6 mm shank rotary accessories. Always confirm the accessory shank size and maximum RPM rating before installation.
• Q: What does rear exhaust mean on an inline die grinder?
  A: Rear exhaust means the tool vents air toward the back of the grinder instead of directly at the work surface. This can help keep chips and grinding dust from being blown across the contact point.
• Q: Can this grinder be used with carbide burrs?
  A: Yes, when the carbide burr has a compatible 6 mm shank and is rated for at least 30,000 RPM. The accessory speed rating must meet or exceed the grinder’s free speed.
• Q: Is this the right tool for cutting wheels?
  A: No. This is an inline die grinder for compatible collet-mounted rotary accessories. Do not mount saw blades, cut-off wheels, or non-approved accessories unless specifically allowed by the manufacturer.
• Q: What compressor size is required?
  A: The provided source information does not list air consumption or recommended hose size. Confirm the full manufacturer catalog specifications before sizing the compressor, hose, and FRL setup.
