The deep-ground flute provides absolute smoothness and high cutting performance. Especially non-breaking chips are transported cleanly as with a twist drill. This reduces the formation of surface cutting and cold welding on the cutting edges. The cone makes it easier to retract when the sheets are drilled through. With this tool, sheets can be centred, drilled, drilled and deburred in one operation. The robust tool is suitable for all common industrial materials, such as non-ferrous metals, stainless steel sheets, thermoplastic and thermosetting plastics as well as all common steel sheets up to a thickness of 4.0 mm.
