Ingersoll Rand 3107G, 1/4 Air Die Grinder
Ingersoll Rand is a brand that the manufacturing industry has grown to trust. Their tools are all well designed, for rugged use and long life. This is proven out in this die grinder, which is built with ball-bearing construction. This is the highest speed die grinder weve looked at, with a maximum speed of 27,000 RPM. The composite case is ergonomically designed for comfort. The throttle is self-locking for security. Like the others weve looked at, this one has a rear exhaust; a must for die grinders.
