ROCKY MOUNTAIN TWIST
ABOUT ROCKY MOUNTAIN TOOL COMPANY
Rocky Mountain Twist (RMT) uses a revolutionary process to transform high-speed steel blanks into precision, high-performance cutting tools for a wide range of markets, from small machine shops to manufacturing facilities and even the medical and aerospace industries.
A U.S. company, based in Ronan, Minn., RMT uses proprietary CNC equipment that enables the company to increase production capacity while maintaining consistently high standards of quality at a lower cost. A sign of superior quality, Rocky Mountain Tool’s products meet or exceed the high tolerance requirements of National Aerospace Standards.
The company’s revolutionary rotary tool manufacturing process involves proprietary CNC drill grinding cells to ensure the highest degree of repeatable tool-making quality in the industry. Departing from traditional processes, in which steel blanks are moved from machine to machine as they are formed into drills, RMT’s process machines its drills, from blank to finished product, in one CNC machine.
RMT’s precise, computer-controlled operation eliminates the process of reorienting the drill at each stage of production, which can result in variances of critical dimensions from one bit to the next.
RMT’s BlackGold Series of cutting tools, available through Hemly Tool, is a product of this precise toolmaking technology. BlackGold drills deliver aggressive cutting dynamics, smoothly drilling through the toughest materials with speed, accuracy and ease for longer tool life. Made of industrial-grade NAS high-speed steel, they feature a 137-degree split point that penetrates on contact; shorter, stronger cutting tips for easier drilling and longer life; and a heavy taper and narrow tip that facilitate faster starts.
RMT high-performance cutting tool lines include jobber length, screw machine, aircraft extension, threaded shank adapted and hex shank products. In addition, RMT engineers and manufactures application-specific cutting tools to meet customers’ exact requirements.
