Dotco 12L2000-01LH Inline Die Grinder | 12-20 Series | 0.6 HP | 25000 RPM | 1/4" Collet | Front Exhaust

Built for deburring, blending, and controlled material removal with carbide burrs and mounted wheels, the Dotco 12L2000-01LH Inline Die Grinder combines 0.6 HP output with a fast 25,000 RPM free speed for smooth cutting action on metal, composites, castings, and fabricated parts. It's 1/4" collet accepts common die grinder accessories, while the inline body gives technicians a straight, pencil-like working angle for edge cleanup, weld dressing, porting, and detail work where a larger right angle grinder would be awkward.

Part of the Dotco 12-20 Series, this model features front exhaust to direct spent air away from the operator’s hand position and a left-hand rotation configuration for applications where burr direction, workpiece orientation, or operator preference calls for reverse rotation versus the standard model. The composite housing helps keep tool weight down, and the grinder is performance rated at 90 PSI for use with properly sized compressed air systems.

Applications:

• Metal fabrication and welding — cleaning weld edges, blending small seams, removing burrs, and touching up cut or machined surfaces.
• Automotive and fleet repair — gasket surface cleanup, casting flash removal, bracket modification, and detail grinding in repair bays.
• Aerospace and composite work — controlled trimming, edge finishing, and precision cleanup where an inline grinder offers better access.
• Industrial maintenance and MRO — removing sharp edges, cleaning slots, preparing small parts, and maintaining fixtures or machinery components.
• Machine shops and tool rooms — deburring drilled holes, smoothing profiles, and using mounted points or carbide burrs on small workpieces.

FAQs:

• Q: What does the LH suffix mean on the Dotco 12L2000-01LH?
  A: LH indicates a left-hand rotation version. This matters when burr direction, operator approach, or part orientation makes reverse rotation more practical than a standard rotation grinder.
• Q: What accessories can be used with this die grinder?
  A: This model uses a 1/4" collet and is rated for a 3/4" carbide burr or a 1-1/2" mounted wheel. Accessories must be compatible with the collet size and rated at or above the tool’s 25,000 RPM free speed.
• Q: What air pressure should this grinder run at?
  A: The tool is performance rated at 90 PSI / 620 kPa. Use a properly regulated air supply and a minimum 1/4" hose I.D. to help maintain consistent speed under load.
• Q: Is this a good grinder for tight spaces?
  A: Yes, the inline body is useful for straight-on access into edges, ports, slots, and small part features. For side access or confined corner work, compare this model with a Dotco angle die grinder.
• Q: Does this grinder include a collet?
  A: Yes. Manufacturer product information lists the applicable collet and collet wrenches as standard equipment.
