ULTIMATECUT Twist drill with FLOWSTEP® tip
- Drills longer. More productivity in use.
- Starts faster. Saves valuable time when pre-drilling.
- Less effort required. Reduces strain and enables sustained, fatigue-free working.
The so-called FLOWSTEP® tip impresses with its performance and makes it unique in terms of speed, ease of movement and drilling results.
The FLOWSTEP® tip
The FLOWSTEP® tip enables precise centering without center punching and faster drilling on different materials and surfaces, such as pipes. Pre-drilling with smaller diameters is completely eliminated, as are time-consuming tool changes. In addition, the FLOWSTEP® tip significantly reduces strain, enabling sustained, fatigue-free work.
The FLOWSTEP® technology
The specially developed, unique cutting edge geometry leads to a much smoother and quieter drilling process thanks to its gentle step transitions, which significantly reduces the machining time and considerably improves the drilling result. FLOWSTEP® technology ensures noticeably effortless operation.
Large diameters. Maximum control.
The innovative FLOWSTEP® tip in combination with the reduced three-fance shank enables extremely efficient and effortless drilling of large diameters from 13.5 to 20.0 mm.
The large dimensions can be drilled directly without the need for pre-drilling or tool changes. FLOWSTEP® technology ensures clean and secure centering of the drill, even on difficult surfaces such as round materials or pipes. The drilling process is smooth and tilt-free, which significantly reduces the effort required and increases the service life of the tool.
The reduced three-face shank ensures maximum power transmission and prevents slipping in the drill chuck.
Ideally suited for use in hand-held (cordless) power tools when precise work with large drill diameters is required.
HSS-Co 5
HSS-Co 5 stands for High-Speed Steel with 5% cobalt content. High-Speed Steel (HSS) is an alloy known for its hardness, wear resistance and heat resistance and is commonly used in tool manufacturing, particularly for drills, milling cutters and other cutting tools. The addition of cobalt in HSSE alloys can improve the performance and life of the tool by increasing its ability to cope with heat and wear.
