For grinding and surface preparation tasks that require extended reach with higher abrasive speed, the Ingersoll Rand M2X180RG4 Extended Straight Grinder combines a 1 HP motor with 18,000 RPM free speed, a 1/4" collet, and rear exhaust. The extended straight configuration helps operators access recessed surfaces, internal areas, and difficult-to-reach work locations, while the collet accepts compatible mounted abrasive accessories for material removal, blending, and surface finishing operations.
The Ingersoll Rand M2X180RG4 provides substantially faster abrasive operation than the lower-speed M2X075RG4 configuration while retaining the added reach of the extended M2 Series tool design. Its 18,000 RPM speed suits compatible mounted abrasives and production processes that benefit from faster material removal and finishing action. Rear exhaust directs discharged air toward the back of the grinder, helping keep the exhaust stream away from the immediate work area and operator interface.
Type: Extended Straight Grinder | Model: M2X180RG4 | Series: M2 Series | Motor Power: 1 HP | Free Speed: 18,000 RPM | Collet Size: 1/4" | Exhaust: Rear
Features:
- 1 HP pneumatic motor provides power for compatible grinding, material removal, blending, and surface preparation operations.
- 18,000 RPM free speed supports fast abrasive action when the grinder is paired with properly rated mounted accessories.
- Extended straight configuration provides additional reach for recessed surfaces, internal features, and difficult-access work locations.
- 1/4-inch collet accepts compatible mounted abrasive accessories with the correct shank diameter and operating speed rating.
- Straight tool layout supports direct alignment with the work area during grinding and surface preparation tasks.
- Rear exhaust routes discharged air away from the immediate abrasive contact area and operator interface.
- Pneumatic operation supports repeated grinding tasks when supplied with clean, regulated, and properly conditioned compressed air.
Applications:
- Metal fabrication — grinding, blending, and preparing surfaces in areas that benefit from the additional reach of an extended grinder.
- Foundry and casting operations — cleaning compatible cast surfaces, recesses, internal features, and other accessible casting areas.
- Weld finishing — removing compatible weld irregularities and blending surfaces where an extended straight tool configuration improves access.
- Equipment maintenance — performing material removal and surface preparation on machinery and components with recessed work locations.
- Production metalworking — supporting repeated abrasive operations where an 18,000 RPM extended straight grinder and 1/4-inch collet match the process requirements.
FAQs:
- Q: What is the advantage of the extended configuration on the M2X180RG4?
A: The extended tool design provides additional reach for recessed surfaces, internal areas, and other work locations where a standard-length grinder may not provide suitable access. - Q: What size abrasive shank fits the Ingersoll Rand M2X180RG4?
A: The grinder is equipped with a 1/4-inch collet. Use only compatible mounted abrasive accessories with the correct shank diameter, suitable dimensions, and an operating speed rating appropriate for the tool. - Q: How does the M2X180RG4 compare with the M2X075RG4?
A: Both supplied models are 1 HP extended straight grinders with a 1/4-inch collet and rear exhaust. The M2X180RG4 operates at 18,000 RPM, while the M2X075RG4 operates at 7,500 RPM, making accessory selection and application requirements important when choosing between the two speeds. - Q: What is the purpose of rear exhaust on this extended straight grinder?
A: Rear exhaust directs discharged air toward the back of the tool, helping keep the exhaust stream away from the immediate grinding area and operator interface. - Q: What should be checked before installing a mounted abrasive accessory?
A: Confirm the accessory has a compatible 1/4-inch shank, suitable dimensions and overhang for the application, and a maximum operating speed rating that meets the tool requirements. Follow the tool and abrasive manufacturer's inspection, mounting, and operating instructions.
