Iskar has added a cutter-replaceable "tool-replaceable large-diameter DR twist drill (φ61-80mm) beam magic drill bit" in the "DR twist drill" series. It is used on the knife body after the blade is mounted on the tool holder. The machining diameter can be changed by using the attached potential piece. Used for drilling of automotive parts, aircraft parts and molds.
Stable machining is achieved by reducing the cutting resistance with a 4-blade design. In order to easily discharge the chips, the blade body increases the width of the groove. In addition, by quenching the tool holder, damage during chip removal is prevented.
The blade is available in a square with four tips and is available in a single 10/11/12mm version. There are two types of chip breakers. The material is also available in PVD (physical vapor deposition) coating material and CVD (Chemical Vapor Deposition) coating material, which can process a variety of materials.
