When you need a compact inline grinder for burr work, edge clean-up, and controlled finishing, the Dotco 12L2001-01LH Inline Die Grinder gives operators a balanced 0.6 HP / 0.45 kW air motor and 20,000 RPM free speed for efficient material removal with compatible carbide burrs and mounted wheels. The inline configuration keeps the accessory in line with the hand position, helping the user guide the tool through deburring, blending, and surface preparation tasks on fabricated parts, castings, brackets, and repair components.This 12-20 Series model uses a 1/4″ 200 Series collet for common 1/4″ shank accessories and is supplied in a front exhaust, left-hand rotation configuration. Left-hand rotation identifies the spindle rotation direction and should be matched only with accessories approved for the tool speed, rotation, and application. At 1.32 lb. and 6.9″ long, the 12L2001-01LH fits production benches, maintenance workstations, tool rooms, and repair shops where a lightweight pneumatic die grinder is easier to control than a larger wheel grinder.Type: Inline Die Grinder | Series: 12-20 Series | SKU: 12L2001-01LH | Motor: 0.6 HP / 0.45 kW | Free Speed: 20,000 RPM | Collet Size: 1/4″ | Collet Series: 200 Series | Rotation: Left Hand | Exhaust: Front | Throttle Type: Lock Off Lever | Abrasive Capacity: 3/4″ Carbide Burr, 1.5″ Mounted Wheel | Housing Material: Composite | Weight: 1.32 lb. | Overall Length: 6.9″ | Air Inlet: 1/4″ | Rated Air Pressure: 90 PSI / 620 kPa | Minimum Hose I.D.: 1/4″ / 6.4 mmFeatures:0.6 HP motor supports everyday die grinding, deburring, and finishing work with compatible carbide burrs and mounted wheels.20,000 RPM free speed provides a useful middle speed in the 12-20 Series for controlled stock removal without stepping up to the 25,000 RPM models.1/4″ 200 Series collet accepts common 1/4″ shank die grinder accessories for metalworking, repair, and production finishing tasks.LH designation identifies this SKU as the Left Hand Rotation Version for applications that require that spindle direction.Front exhaust layout directs exhaust forward from the tool rather than through a rear exhaust or overhose configuration.Composite housing keeps the grinder lightweight while providing a practical gripping surface for repeated workstation use.Lock off lever throttle helps reduce unintended starts during handling, setup, or repositioning.Standard equipment includes the applicable collet and collet wrenches; optional collet guard 01-2047PT is supplied separately.Made in USA: Applications:Fabrication shops removing burrs from cut edges, cleaning small weld areas, and blending localized surface marks on steel or aluminum components.Die, mold, and tool room work shaping pockets, easing edges, and finishing detail areas where an inline grinder gives direct control at the workpiece.Maintenance and MRO departments cleaning gasket surfaces, touching up brackets, and preparing small machine parts for repair or reassembly.Automotive and fleet repair port clean-up, bracket modification, small casting work, and general grinding tasks in service or rebuild areas.Production benches repeat deburring and part finishing where a compact 1/4″ collet grinder is easier to maneuver than larger pneumatic grinders.FAQs:Q: What does LH mean on the 12L2001-01LH?A: LH means Left Hand Rotation Version.
