High roundness and alignment accuracy of the deep hole.
Note:
For process reliability when using the 16×D deep-hole drill, an initial centre drilling with No. 121068 – 121130 or 4×D pilot drilling operation with pilot drill No. 122736 is necessary. For deep holes greater than 20×D, a 6×D pilot hole with pilot drill No. 122736 is absolutely essential. The generation of a pilot hole improves process reliability. See also pages 129/130.
