Safety

Noise is a nuisance and can be harmful to your health. Ingersoll Rand 301B Air Angle Die Grinder has a silencer to enhance your safety during operation as it traps noise produced.

The grinder also has an integral safety lock throttle lever which prevents accidental startup of the machine. It also has a 360 degrees front exhaust to help keep work safe and directs air away from the user.

Powerful Effort

Ingersoll Rand 301B Air Angle Die Grinder is a very powerful machine. Its motor produces 0.25 horsepower at a speed of 20,000 revolutions per minute. You can imagine that kind of speed, about 330 cycles per second. This is very powerful and will make your work first enhancing your job efficiency.

Not that the air pressure which drives the motor should not be more than 90 psi from your air compressor. Otherwise, you will be wasting energy, and your machine will wear out easily since you will have surpassed the maximum allowable limit.

Strong Casing

A strong casing for a machine is necessary to withstand tough operations. This will prevent the machine from breakages and internal damages.

This grinder has a very strong aluminum for this case. It also has a compact design feature for easy storage; you don’t need to be worried about space in your workshop.
