Dotco 12L1082-36 Inline Grinder | 12-10 Series | 0.3 HP | 25,000 RPM | 1/4" Collet | Composite Housing | Rear Exhaust

Built for controlled deburring, die work, and small-area finishing, the Dotco 12L1082-36 Inline Grinder gives operators a compact straight-line tool for burrs, mounted wheels, and precision material removal. Its 12-10 Series configuration combines a 0.3 hp motor with 25,000 RPM free speed, giving the tool the speed needed for carbide burr cutting and fine surface cleanup without stepping up to a larger grinder body. The 1/4" collet accepts common industrial burrs, while the rear exhaust directs spent air away from the work area and helps keep chips and dust from being blown forward onto the part.

This inline die grinder uses a composite housing with an elastomer coating and balanced moving parts to help reduce vibration during repeated use. At 6.0" overall length, the tool is sized for close control in fixture work, mold cleanup, weld blending, and confined-area deburring where a pistol grip or angle grinder can be harder to position. A lock-off lever adds a safety-focused start control by helping reduce unintended activation during handling or repositioning.

• 25,000 RPM free speed provides the high rotational speed required for compatible carbide burrs and small mounted wheels.
• 1/4" collet accepts common industrial die grinder accessories used for burr work, blending, and part cleanup.
• Composite housing with elastomer coating helps improve grip and reduce transmitted vibration during repeated tool use.
• Balanced moving parts help keep tool vibration to a minimum for better control during precision finishing passes.
• Rear exhaust directs air away from the front of the tool to help keep the work area clearer while grinding or deburring.
• Lock-off lever helps prevent accidental start-up when the tool is being handled, moved, or repositioned.
• Compact 6.0" length helps operators reach confined work areas around fixtures, molds, welds, and assembled components.

Applications:

• Die and mold work — cleaning parting lines, refining small cavities, and removing excess material with compatible carbide burrs.
• Metal fabrication — deburring cut edges, blending tack welds, and finishing small features where a larger grinder is difficult to control.
• Transportation and fleet maintenance — cleaning brackets, small castings, welds, and service parts before repair or reassembly.
• Welding and repair shops — removing spatter, smoothing localized weld areas, and preparing small surfaces for finishing.
• Industrial MRO — everyday maintenance deburring, gasket-surface cleanup, and controlled material removal on machinery components.
• Garage and workshop use — precision burr work and small mounted-wheel grinding when paired with the correct air supply and rated accessories.

FAQs:

• Q: What accessories can be used with the Dotco 12L1082-36?
  A: This grinder uses a 1/4" collet and is listed with an abrasive capacity of a 1/2" carbide burr or 1" mounted wheel. Always verify that the accessory shank fits the collet and that the accessory speed rating equals or exceeds 25,000 RPM.
• Q: What does rear exhaust mean on an inline grinder?
  A: Rear exhaust means the tool vents air toward the back of the grinder instead of toward the workpiece. This helps keep chips, dust, and debris from being blown directly across the cutting area.
• Q: Is this a pencil grinder or a die grinder?
  A: This is an inline die grinder. It uses a 1/4" collet and is suited for carbide burrs and mounted wheels, while pencil grinders are typically smaller, higher-speed tools used with smaller collets for very fine finishing.
• Q: Can this grinder be used in tight spaces?
  A: Yes, the inline body and 6.0" overall length make it useful for reaching around fixtures, dies, welds, and assembled components. For right-angle access, a 90-degree angle die grinder may be a better choice.
• Q: Why does abrasive speed rating matter?
  A: A mounted wheel or burr must be rated for at least the grinder’s 25,000 RPM free speed. Using an accessory below the tool speed rating can cause accessory failure and serious injury.
