DLTUK60 series-Solid Carbide Rods with 2 helical coolant holes(30°)
Literal statement:
The production of carbide rods with helical twisted coolant holes is made less expensive thanks to new production processes . The use of a continuous twisting process with simple spiral nozzles allows increased automation. The development of new plastifying agents makes it possible to produce carbide rods with diameters of up to 25 mm using extrusion presses. The optoelectronic monitoring and control of the new production process ensures the quality requirements placed on carbide rods with helical twisted coolant holes with regard to various carbide grades.

Due to the new production process, helical twisted coolant hole carbide rods have decreased production costs. The use of simple spiral nozzle continuous twisting process can improve the degree of automation. The development of new plasticizers made it possible to produce carbide rods up to 33 mm in diameter on extruders. Optoelectronic monitoring and control of the new production process ensures the quality requirements for helical twisted coolant hole carbide rods for a wide range of carbide grades.
