Tungaloy Corporation is pleased to introduce TungJet, innovative toolholders for high pressure coolant, which provide outstanding productivity.

In conventional coolant machining, it is sometimes difficult to deliver coolant accurately to the cutting point because the chips created during the operation interrupt smooth coolant supply. To solve this problem, TungJet supplies high pressure coolant from two directions: coolant is delivered directly to the cutting point through the toolholder’s top nozzle that is located very close to the cutting edge and to the insert’s clearance surface through the frontal coolant hole.

High pressure coolant supplied from the top nozzle forms short chips in machining of heat-resistant alloys that usually has trouble with chip control. Plus, coolant prevents crater wear from developing on insert’s rake face as the heat generated in the operation is dispersed, which results in stable tool life in high-speed cutting. Long tool life is also achieved by coolant from the frontal hole as coolant supplied to the cutting point prevents flank wear.

Even under normal coolant pressure with existing equipment, TungJet improves tool life, and the benefit can be enjoyed for stainless and alloy steels as well as heat-resistant alloys. This advanced tool series drastically increase efficiency and productivity especially in aerospace, automotive, and general machining industries.

In addition to tools for general external turning, TungJet is applicable for other tools which receive favorable reputation in the market, such as EcoTurn, the economical and functional tool line-up, DoMiniTurn and J-series for small-part machining, and covers a wide range of applications in various industries.

Main features:

• High pressure coolant increases productivity by forming short chips in machining difficult-to-cut materials and gummy steels.
• Coolant supplied to insert’s rake face and clearance surface extremely improves machining of various workpiece materials due to good chip control and strong wear resistance.

Tungaloy Corporation is pleased to announce the expansion of round shanks for DoMiniTurn / External Line. The round shank can be applied to sleeve holder for main and sub spindles on automatic lathes and increases the efficiency in external turning of miniature parts. For this newly developed round shank, the double-sided DXGU inserts are applicable.

DoMiniTurn is the innovative tool that is already well-recognized in such industries as automotive, IT, and medical for its high functionality and productivity in small-part machining using the automatic, Swiss lathe – where one-sided, positive inserts are widely used. With DoMiniTurn’s innovative double-sided insert geometry, however, the cutting force is maintained as low as that of the positive insert while doubling the number of cutting edges, thus dramatically reducing the tool cost.

Responding to the market demand, 10 types of round shanks are available in different diameters and lengths for various machines. This addition of round shanks to the DoMiniTurn / External Line, combined with square shanks which are already available in the market, help increase the customers’ productivity and provide significant cost reduction in a wide range of applications on automatic lathes.
