The HSS-TiN countersink is a highly useful tool. The cylindrical shank allows mounting in drills, screwdrivers, or milling machines. The countersink is used for deburring and countersinking holes and should be operated at low speeds.
It is suitable for working with all types of metals such as steel, cast iron, and non-ferrous metals. The HSS-TiN STALCO PERFECT countersink offers excellent durability and service life. It is made of high-speed steel (HSS), and the working tip is additionally coated with titanium nitride.
Thanks to this coating, the tool maintains its dimensions for a long time, even when working with difficult materials. Work efficiency is further enhanced by the 90-degree countersink angle and three cutting edges. The countersink is available in three diameters: 6.3 mm, 12.4 mm, and 20.5 mm, allowing the processing of many standard screw holes.
FEATURES AND BENEFITS:- Ground, sharp cutting edges speed up work and reduce processing time
- Ideal for working with metals, wood, and plastics
- Allows precise countersinking and finishing of holes
- Very long service life significantly reduces operating costs
- TiN coating greatly improves efficiency and working comfort
- Conical countersinks DIN 335 / 90°
- Structural coating: TiN titanium nitride coating
- Optimal ratio of hardness to internal stress, ensuring high geometry stability and even wear of cutting edges
- Higher thermal and chemical resistance, enabling dry machining at higher speeds and reduced flank wear
- Improved sliding properties, resulting in better chip formation and higher surface quality
- Greater wear resistance, reducing tooling costs
- Maximum operating temperature approx. 600°C
