Each of the Die Grinders features a rubber grip to help keep the user’s hand isolated and protected from low temperatures as the unit gets cold from use.

The speed control is located on the body of the tool and allows for tool-free adjustment, unlike some competitive units that require a screwdriver to adjust.

With both .3 and .5 heavy-duty horsepower motor options, the line offers solutions for a wide range of applications for multiple industries including fleet maintenance, oil & gas, metal fabrication, repair/maintenance, and light manufacturing.

The Proto Die Grinders each feature a 360 degree rotating exhaust that allows the user to direct exhaust away from them.

Additionally, the precision collet provides for accurate material removal. Varying from 1 to 2 pounds, the low weight of each unit is also a factor that provides user-satisfaction.
