DoMini-Mill Copy Mill

For semifinishing of die and mold, solid and head-changeable endmills are among the most popular tools used. Due to their cutting edge sharpness, however, these tools are not durable enough to bring feed per revolution high enough to achieve the machining performance required, thus resulting in longer machining times and higher tool cost.

DoMini-Mill is a copy mill developed for semifinishing operations, featuring Tungaloy’s latest H-class insert. The economical six-cornered insert with dovetail clamp technology has a double-sided geometry, yet positive flanks, providing sharpness and high cutting edge strength simultaneously. By combining the insert’s durability and the density of the cutter body, feed rates can be drastically increased compared with conventional products. The insert grade is available in AH110, providing stable and long tool life in machining carbon steel to hard materials up to HRC 60. The cutter body can also be connected to TungFlex, the modular system with a metric thread connection, extending the tool overhang in order to meet the customers’ most demanding applications.
