The HEX shank has several benefits over the CYL shank.
While both shank types fit into three-jaw chucks of a standard drill, the HEX shank offers a more secure connection: due to its geometry it won’t slip in the chuck.
The HEX shank ensures maximum power transfer from your machine to the drill bit.
The HEX shank also gives you more flexibility when choosing your tool: you can use it with standard drills with three-jaw chucks as well as impact drivers with ¼” internal hexagon tool holders.
The 3-wing shank of our CYL-5 drill bits only fits three-jaw chucks, but otherwise it offers benefits similar to those of the HEX shank: it fits in the chuck securely, it doesn’t slip and ensures maximum power transfer from your machine to the drill bit.
