It supports deep hole machining from φ1.5 to φ24, up to a maximum of 750mm (depending on the hole diameter).
The deep hole machining of Casttec using the latest gun drill technology can accommodate depths of up to 280mm for φ1.5, 440mm for φ2, and 750mm for φ6 (for round-shaped materials). The above refers to hole machining from one direction, not from both sides, so there will be no connecting steps in between. Additionally, for die-casting core pins, smoothing the tip of the hole to a smooth SR shape helps suppress the occurrence of cracks during use. We have processing achievements not only with SKD61, a hot work tool steel mainly used in die casting, but also with various types of steel for plastic molds, stainless steel, copper, and brass.

Company information
We mainly manufacture core pins, inserts, sprue cores, and sprue bushes for die casting. Since February 2019, we have started producing inserts with complex cooling structures using metal 3D printers (maraging steel, improved SKD61 steel), and in May 2024, we introduced a fluid polishing machine. Additionally, we are confident in our hole processing capabilities, being able to process holes as small as φ1.5 to a depth of 280mm, and φ2 holes to a depth of 440mm (for both through holes and blind holes). Since our production is primarily made to order, we can accommodate requests starting from one piece. In addition to hot work tool steel commonly used in die casting, we also have processing experience with materials such as cold work tool steel, high-speed tool steel, and stainless steel (SUS303, SUS304, SUS310, SUS630), so customers from fields other than die casting are also welcome to inquire.
