Rocky Mountain Twist (RMT) History

RMT is an industry leader in design, engineering and manufacturing of high performance cutting tools. Founded in 2001, Rocky Mountain Twist headquarters and 300,000 square foot manufacturing facility is located at the base of the Rocky Mountains in Ronan, Montana a region known for great hunting, fly-fishing, four-season recreation, and now superior performance made in the USA industrial cutting tools.

Cutting-Edge Technology

Advancements through technology and process improvements have positioned Rocky Mountain Twist as the quality and performance leader of industrial drill bit manufacturing.

Until recently the process of grinding a drill bit from a solid high-speed steel blank has changed very little over the years. A drill bit produced using traditional manufacturing methods is ground in multiple remote operations within a batch. After each shaping operation the drill bits must be moved manually to the next machine or operation. This process is repeated until bits are completely ground. Herein lies the problem, each time a drill bit moves from one operation to the next, the bit is reoriented within a fixture. This constant reorientation can create variances of critical dimensions from one bit to the next. These variations in geometry translate to reduced performance and inconsistencies in hole size.
