For high-speed grinding, deburring, and surface preparation tasks that benefit from angle-head access, the Ingersoll Rand M2A180RG4 M2 Series Angle Grinder combines a 1 HP motor with 18,000 RPM free speed, a 1/4" collet, and rear exhaust. The angle configuration helps position compatible mounted abrasive accessories against edges, surfaces, weld areas, and component features where the approach of a straight grinder may be less practical.
The Ingersoll Rand M2A180RG4 provides faster abrasive operation than the 12,000 RPM M2A120RG4 while retaining the same collet-mounted angle configuration. Its 18,000 RPM operation supports compatible mounted abrasives used for material removal, blending, and finishing, while the 1/4" collet allows the tool to accept accessories with the correct shank diameter and speed capability. Rear exhaust routes discharged air toward the back of the grinder, helping keep the exhaust stream away from the immediate abrasive contact area.
Type: Angle Grinder | Model: M2A180RG4 | 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, deburring, blending, material removal, and surface preparation operations.
- 18,000 RPM free speed supports high-speed abrasive action when paired with mounted accessories rated for the tool speed and operating conditions.
- 1/4-inch collet accepts compatible mounted abrasive accessories with the correct shank diameter and maximum permissible speed.
- Angle-head configuration improves tool positioning on surfaces, edges, weld areas, and component features where an angled approach suits the work geometry.
- Collet-mounted configuration supports compatible shank-mounted abrasive accessories rather than threaded wheel-mounting arrangements.
- Rear exhaust directs discharged air toward the back of the tool and away from the immediate abrasive contact area.
- Pneumatic operation supports repeated grinding tasks when supplied with clean, regulated, and properly conditioned compressed air.
Applications:
- Metal fabrication — removing burrs, blending edges, and preparing surfaces with compatible mounted abrasive accessories.
- Weld cleanup — grinding and blending accessible weld areas where the angle-head configuration provides a suitable approach to the workpiece.
- Foundry and casting operations — cleaning compatible cast surfaces and component features suited to high-speed collet-mounted abrasives.
- Equipment maintenance — performing localized material removal and surface preparation on machinery, fabricated parts, and metal components.
- Production metalworking — supporting repeated abrasive processes where an 18,000 RPM angle grinder with a 1/4-inch collet matches the application requirements.
FAQs:
- Q: What size abrasive shank fits the Ingersoll Rand M2A180RG4?
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 operating overhang, and a maximum permissible speed appropriate for the tool. - Q: What is the free speed of the M2A180RG4?
A: The specified free speed is 18,000 RPM. Any mounted abrasive accessory used with the grinder must be compatible with the 1/4-inch collet and rated for the actual operating speed and use conditions. - Q: How does the M2A180RG4 compare with the M2A120RG4?
A: Both supplied models are 1 HP M2 Series angle grinders with a 1/4-inch collet and rear exhaust. The M2A180RG4 operates at 18,000 RPM, while the M2A120RG4 operates at 12,000 RPM, making the M2A180RG4 the faster-running configuration. - Q: When is an angle grinder with a collet useful?
A: A collet-equipped angle grinder can be useful when compatible shank-mounted abrasives are needed and the angled tool head provides a more suitable approach to edges, surfaces, weld areas, or component features than a straight configuration. - 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 operating overhang, and a maximum permissible speed that meets the tool requirements. Follow the tool and abrasive manufacturer's inspection, mounting, and operating instructions.
