Ingersoll Rand M2A120RG4 M2 Series Angle Grinder | 1 HP | 12000 RPM | 1/4" Collet | Rear Exhaust

For grinding, deburring, and surface preparation tasks that require angle-head access with high-speed mounted abrasive operation, the Ingersoll Rand M2A120RG4 M2 Series Angle Grinder combines a 1 HP motor with 12,000 RPM free speed, a 1/4" collet, and rear exhaust. The angle configuration helps position compatible mounted abrasive accessories against surfaces, edges, weld areas, and component features where an angled tool head provides more practical access than a straight grinder layout.

The Ingersoll Rand M2A120RG4 uses a collet-mounted accessory configuration rather than the threaded spindle arrangement found on wheel-equipped M2 angle grinder models. Its 12,000 RPM operation supports compatible mounted abrasives used for material removal, blending, and surface preparation, while the 1/4" collet allows buyers to match the tool with accessories of the correct shank diameter and speed rating. Rear exhaust routes discharged air toward the back of the tool, helping keep the exhaust stream away from the immediate work area.

Type: Angle Grinder | Model: M2A120RG4 | Series: M2 Series | Motor Power: 1 HP | Free Speed: 12,000 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.
• 12,000 RPM free speed supports controlled 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 provides practical access to surfaces, edges, weld areas, and component features where straight tool alignment may be less convenient.
• Collet-mounted design allows use with compatible mounted abrasives rather than M14 or 5/8-inch threaded wheel-mounting configurations.
• Rear exhaust directs discharged air toward the back of the grinder 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 — deburring edges, blending surfaces, and removing localized material with compatible mounted abrasive accessories.
• Weld finishing — cleaning and blending accessible weld areas where the angle-head configuration improves positioning against the workpiece.
• Foundry and casting operations — removing surface imperfections and cleaning compatible cast features suited to collet-mounted abrasives.
• Equipment maintenance — performing grinding and surface preparation on machinery, fabricated parts, and metal components.
• Production metalworking — supporting repeated abrasive operations where a 12,000 RPM angle grinder with a 1/4-inch collet matches the process requirements.

FAQs:

• Q: What size abrasive shank fits the Ingersoll Rand M2A120RG4?
  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 M2A120RG4?
  A: The specified free speed is 12,000 RPM. Mounted abrasive accessories must be compatible with the 1/4-inch collet and rated for the actual operating speed and use conditions.
• Q: How does the M2A120RG4 differ from threaded-spindle M2 angle grinders?
  A: The M2A120RG4 uses a 1/4-inch collet for compatible shank-mounted abrasive accessories. Threaded-spindle M2 angle grinders use specified spindle threads and mounting hardware for compatible grinding wheels or other threaded accessories.
• Q: What is the benefit of the angle-head configuration?
  A: The angle head can improve tool positioning on surfaces, edges, weld areas, and other workpiece features where a straight grinder configuration may not provide the preferred approach angle.
• 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.
