Core drill set, HSS, 7 pieces Suitable for steel (such as T-carrier, large-sized sheets), cast steel, non-ferrous and light metals. With an advanced blade geometry, a significantly improved cutting performance is achieved, which has a positive effect on the cutting performance and tool life. 1. Optimised cutting edge geometry for increased cutting performance and reduced cutting forces. 2. The rake angle are designed for universal use in various types of steel. 3. Improved chip evacuation by U-shaped outlet. The special geometry of the outlet reduces the thermal load on the HSS core drill, because the heat generated during machining is largely dissipated by the chip. 4. Reduce the friction between the HSS core drill and the work piece through optimised, spiralling circular lands.
