For grinding and material removal tasks that require added reach with controlled abrasive speed, the Ingersoll Rand M2X075RG4 Extended Straight Grinder combines a 1 HP motor with 7,500 RPM free speed, a 1/4" collet, and rear exhaust. The extended straight configuration helps operators reach recessed surfaces, internal areas, and work locations where a standard-length grinder may have limited access, while the collet holds compatible mounted abrasive accessories for grinding and surface preparation operations.
The Ingersoll Rand M2X075RG4 provides a lower-speed configuration for compatible abrasive accessories and material removal processes that do not require the higher operating speeds of other M2 Series grinders. Its 7,500 RPM operation supports controlled abrasive action, while the extended body improves reach into difficult work areas. 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.

Applications:
- Metal fabrication — removing material and preparing surfaces in areas that benefit from the added reach of an extended grinder.
- Foundry and casting work — cleaning compatible cast surfaces and reaching internal features, recesses, and other accessible casting areas.
- Weld cleanup — grinding and blending compatible weld areas where a straight extended tool configuration improves access.
- Equipment maintenance — performing surface preparation and material removal on machinery and components with recessed work locations.
- Production metalworking — supporting repeated abrasive operations where a 7,500 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 M2X075RG4?
A: The extended tool body 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 M2X075RG4?
A: The grinder is equipped with a 1/4-inch collet. Use only compatible mounted abrasive accessories with the correct 1/4-inch shank size and an operating speed rating suitable for the tool. - Q: What is the free speed of the M2X075RG4?
A: The grinder has a specified free speed of 7,500 RPM. Select mounted abrasive accessories that are compatible with the collet and rated for the grinder's operating speed. - Q: What is the purpose of rear exhaust on this extended grinder?
A: Rear exhaust routes 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 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.
