Built for precision deburring, carbide burr work, weld blending, and light material removal, the Dotco 12L2500-01 inline grinder combines a 0.9 HP air motor with a 23,000 RPM free speed to deliver fast, controlled cutting performance across metal fabrication, aerospace, maintenance, and manufacturing environments. Its inline configuration provides excellent alignment with the workpiece, while the 1/4" collet accepts a wide range of common carbide burrs and mounted accessories for versatile finishing operations. The front exhaust directs airflow away from the operator while helping clear debris from the work area, improving visibility during detailed grinding tasks.
The composite housing helps reduce tool weight while providing durability for everyday industrial use. Elastomer grip surfaces and balanced internal components help minimize vibration during extended operation, making the grinder well-suited for production environments where precision and control are essential. The inline design also offers excellent access when working inside fixtures, fabricated assemblies, and narrow work areas where larger grinders can be difficult to maneuver.

FAQs:
- Q: What accessories fit the 1/4" collet?
A: The grinder accepts standard 1/4" shank carbide burrs, mounted points, and other compatible rotary accessories designed for a 1/4" collet. - Q: What does the front exhaust do?
A: The front exhaust directs spent air away from the operator while helping move grinding debris away from the immediate work area for improved visibility. - Q: Is this grinder suitable for precision work?
A: Yes. The inline configuration provides a straight, pencil-like working position that helps improve control during deburring, edge finishing, and detailed grinding operations. - Q: Can I use any abrasive with this grinder?
A: Only use accessories that fit the 1/4" collet and have a maximum rated operating speed equal to or greater than the tool's 23,000 RPM free speed.
