Dotco 12L1045-36 Inline Grinder | 12-10 Series | 0.3 HP | 12,000 RPM | 1/4" Collet | Composite Housing | Front Exhaust

Built for controlled deburring, blending, and small-area grinding, the Dotco 12L1045-36 Inline Grinder gives operators a straight-body pneumatic tool for 1/4"-shank accessories used in metalworking, repair, and production finishing. Its 12-10 Series configuration pairs a 0.3 hp motor with 12,000 RPM free speed, making it a practical choice when the job calls for more controlled material removal than higher-speed die grinders. The 1/4" collet accepts common burrs and mounted points, while the composite housing helps keep the tool manageable during repeated bench, fixture, and in-place cleanup work.

The front exhaust configuration vents air toward the front of the tool rather than out the rear, which can be useful when rear-directed exhaust would interfere with the operator’s hand position, air line routing, or nearby components. As an inline grinder, the 12L1045-36 is well suited for straight-in access on slots, holes, castings, machined edges, weld areas, and small surface transitions where a compact air grinder provides better control than a larger wheel grinder.

Type: Inline Grinder | Series: 12-10 Series | Motor: 0.3 hp | Free Speed: 12,000 RPM | Collet Size: 1/4" | Housing: Composite | Exhaust Type: Front

Features:

• Inline grinder body supports straight, controlled positioning for deburring, blending, and finish-grinding tasks.
• 12,000 RPM free speed provides a controlled cutting rate for compatible 1/4"-shank burrs, mounted points, and grinding accessories.
• 0.3 hp pneumatic motor supplies useful power for localized material removal without requiring a larger grinder format.
• 1/4" collet works with common industrial die grinder accessories used in fabrication, maintenance, and repair work.
• Composite housing helps reduce tool weight compared with all-metal housings and supports better handling during repeated use.
• Front exhaust vents air forward, which may be preferred where rear exhaust would blow toward the operator or interfere with the air hose path.
• Straight-line configuration helps operators maintain control when working along edges, inside openings, and around fixtures.

Applications:

• Metal fabrication — deburring cut edges, cleaning drilled holes, and blending small surface transitions after machining or cutting.
• Maintenance and MRO — removing minor burrs, gasket residue, corrosion, and raised edges from service parts before reassembly.
• Welding and repair shops — smoothing localized weld areas, cleaning spatter, and preparing small repair zones for finishing.
• Die, mold, and fixture work — refining slots, pockets, radii, and detail areas where straight access and tool control matter.
• Automotive and fleet service — cleaning brackets, housings, castings, and small metal parts during repair or restoration work.
• Workshop and garage use — controlled grinding and burr work when paired with a properly sized compressor and rated accessories.

FAQs:

• Q: What accessories fit the Dotco 12L1045-36?
  A: This grinder uses a 1/4" collet, so it is intended for compatible 1/4"-shank accessories. Always confirm the accessory diameter, shank size, and maximum RPM rating before use.
• Q: What does front exhaust mean on this grinder?
  A: Front exhaust means the tool vents air toward the front of the grinder. This can help keep exhaust away from the operator’s hand area, but it may also move chips or dust near the workpiece, so eye and face protection are essential.
• Q: Is 12,000 RPM considered high speed for a die grinder?
  A: It is slower than many 20,000–25,000 RPM die grinders, which can make it useful for more controlled grinding and finishing. The correct speed depends on the accessory type, diameter, material, and workpiece.
• Q: Can this tool be used with carbide burrs?
  A: Yes, when the burr has a compatible 1/4" shank and is rated for at least 12,000 RPM. Check the burr manufacturer’s speed limits and application guidance before mounting it in the tool.
• Q: What air system setup should be used with this grinder?
  A: Use clean, regulated, lubricated air and verify compressor capacity against the manufacturer’s air consumption data before continuous use. A properly sized FRL helps maintain tool performance and protects internal components.
