DLTUK60 series-Carbide Rods with 3 helical coolant holes(30°)
Literal statement:
Three helical coolant holes cemented carbide rods are rods with three helical coolant holes. They could applied to many cases, including drill bits, end mills, and reamers. Customized diameters and length are also available in these grades as well as metric sizes.
Especially at the high temperatures, the hardness and toughness of the sintered materials are the keys to improve the capability of cemented carbide rods. These properties are also the result of a good balance between WC grain size and binder content.

Tungsten carbide rods are made by mixing hard and wear resistant particles of different sizes (tungsten carbide) and are made by mixing and combining a ductile metal (cobalt, nickel, chromium, iron). In order to get the best performance in a given application, sometimes a small amount of alloying is required to deal with specific attributes. Very accurate composition of the mixture, combined with the specific sintering process, will eventually come to the mechanical properties of the product.
Customized soltuion is aviable for tungsten carbide rods With 2 Helical Coolant Channels
