Extra long multi-area twist drill with cylinder shank. The multi-problem solver in the deep hole area twist drill for particularly deep holes. Thanks to the ultra-flat groove profile (wide flute angle, larger side clamping angle), even extra long drills achieve the required stability (the core is reinforced, but without rise) and can simultaneously promote the chips well with large drilling depths (approx. 10 to 15 x ..; depending on the material), it is recommended to ventilate the drill at regular intervals, use: for medium and long chipping materials with a strength up to a maximum of 1,200 N/mm2, for Al/copper/AlSi alloys, soft bronze, electrolytic copper, brass tough, stainless steels, V2 A. and V4 A Steels, titanium, titanium alloys.
