The DIN 335 C HSSE fi 12.4 mm 90-degree tapered countersink is a professional cutting tool designed for precision countersinking of tapered bolt holes and edge chamfering in structural metals and hard-to-machine alloys. Made from HSSE high-speed steel with added cobalt, it offers enhanced wear and heat resistance, making it a durable solution for demanding users.
The three working blades used guarantee exceptional working stability, uniform cutting and no vibration even at higher machining speeds. Thanks to this, the conical countersink fi 12,4 mm 90 degrees provides excellent surface quality and minimizes the need for additional finishing.
The product is recommended as a conical countersink for metal, including a tool for stainless steel, aluminum, brass or bronze. The high-quality cutting surface facilitates chip evacuation and prevents excessive heating of the tool.
- Three working blades - ensure quiet, precise and stable operation of the tool without the effect of vibration.
- HSSE steel with cobalt - guarantees longer life and resistance when machining hard-to-machine materials.
- High-quality surface - produces clean, smooth countersinks without burrs.
- Universal application - ideal as a conical countersink for metal in series and workshop production.
- Can work with inox - works well as a conical countersink fi 12.4 mm 90 degrees for stainless steel.
Conical countersinkfi 12,4 mm 90 degrees is a precision tool for professionals who value durability, accuracy and quality machining at the highest level.
