HSS-TiN countersink ø20.5 mm, Length 63 mm, Shank ø10 mm STALCO PERFECT S-72511

The HSS-TiN conical countersink is a highly practical 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 conical countersink offers excellent durability and long 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. The 90-degree countersink angle and three cutting edges ensure high efficiency. The countersink is available in diameters of 6.3 mm, 12.4 mm, and 20.5 mm, allowing work with many standard screw holes.

• Ground, sharp cutting edges speed up work and reduce processing time
• Ideal for working with metals, wood, and plastics
• Enables precise countersinking and finishing of holes
• Very long service life significantly reduces operating costs
• TiN coating greatly increases efficiency and working comfort

• Conical countersinks DIN 335 / 90°
• Structural coating: TiN titanium nitride coating

• Optimal hardness-to-stress ratio ensuring high cutting-edge geometry stability and even wear
• Higher thermal and chemical resistance allowing dry machining at higher speeds and reduced flank wear
• Improved sliding properties for better chip formation and higher surface quality
• Greater wear resistance, reducing tooling costs
• Maximum operating temperature approx. 600°C

The DIN 335, 90° conical countersink is designed for professional machining of holes at a 90-degree angle. It is suitable for enlarging, countersinking, and face machining of holes, especially for creating seats for countersunk screws.

Manufactured according to DIN 335 dimensional standards from special high-speed HSS steel. The high-quality titanium nitride (TiN) coating is abrasion-resistant and suitable for machining steel, non-ferrous metals, and thermoplastically and thermoset-reinforced plastics.

Suitable drive tools: handheld drill, column drill.
