When selecting drills, countersinks, or milling cutters, many people initially focus on the material, length, or tip angle. However, one detail is just as important: the shank. It influences power transmission, grip, concentricity, and ultimately the machining result.
This article provides an overview of the most common tool shanks and their areas of application. We also show you where their strengths lie and when you need which one.

RUKO is expanding its ULTIMATECUT countersink range with the introduction of the countersink 4S with HSSE-Co 5 alloy to increase the efficiency and tool life of the tool.
Since 1974, the name RUKO has stood for outstanding drilling and cutting tools - and highly competent employees who seem to have been born working with the tools. With state-of-the-art production, constant product optimisation and numerous innovations, RUKO has developed into a leading supplier in the tool industry
In metal cutting, choosing the right speed is crucial to achieving the best quality end product. An incorrect speed can not only affect the quality of the machined material, but also shorten the tool life. To ensure that the correct speed is selected, speed tables are an indispensable tool in metal cutting.
Can you talk about real innovation in a countersink? Can you really make a professional countersink visibly - and more importantly - noticeably better?
To put it in a nutshell, it can. The new RUKO ULTIMATECUT 4S countersink provides the proof and completely reinterprets countersinking. It works faster, works more efficiently, saves power and is also many times more durable than conventional countersinks.
