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.

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. Before using the tool, confirm the accessory is rated for 20,000 RPM and approved for the grinder’s rotation direction. - Q: What accessories can this Dotco die grinder run?
A: This model uses a 1/4" 200 Series collet and is rated for a 3/4" carbide burr or 1.5" mounted wheel. Accessories must be compatible with the tool’s collet size, speed, and application. - Q: Is this a front exhaust or rear exhaust grinder?
A: The 12L2001-01LH is a front exhaust grinder. If your workstation requires a rear exhaust or overhose setup, compare it with the rear exhaust versions in the same 12-20 Series. - Q: What air line setup does this tool require?
A: The catalog rates the tool at 90 PSI / 620 kPa and lists a 1/4" minimum hose I.D. Use clean, regulated, lubricated air and avoid undersized hoses that can reduce grinder speed under load. - Q: Does the grinder include the collet guard?
A: The catalog lists the applicable collet and collet wrenches as standard equipment. Optional collet guard 01-2047PT is supplied separately.
