Article no.: 123691
18 variants
Note: Flute length LC = L2 + 1.5 × DC. To achieve good process reliability with 40×D and 50×D deep hole drills it is absolutely essential to drill a pilot hole with maximum drilling depth with drill No. 122736 and a 20×D co-pilot hole with a co-pilot drill No. 123691.The generation of a pilot hole improves process reliability.
