DIN 335 B HSS conical countersink fi 120 mm 90 degrees is a high-performance cutting tool designed for precision machining of large diameter holes at ninety degrees. Made from durable HSS high speed steel, it meets the requirements of DIN 335 B, guaranteeing reliable results in professional manufacturing environments.
Thanks to its Morse taper shank, the tool provides rigid clamping even under heavy loads, resulting in stable and safe operation. The 3-blade design enables even cutting and effective vibration dampening, which in turn ensures accurate machining and extended tool life.
This metal taper countersink is designed for heavy use on large machine tools and CNC centers, where an effective and durable tool is required. It is also ideal as a fi 120 mm 90 degree taper countersink for stainless steel, offering high quality finish and reliability in difficult-to-machine materials.
The tool's high-grade workmanship and high-quality surface enable efficient chip evacuation and reduce workpiece adhesion.
- Stable three-edge design - reduces vibration and enables precise guidance of the tool in the material.
- Morse shank - ensures secure clamping under heavy cutting loads.
- Durable HSS steel - guarantees wear resistance and long life when working with metals and stainless steel.
- Large-diameter machining - ideal for preparing screw seats in structural components.
The conical countersink fi 120 mm 90 degrees is an industrial grade tool for demanding machining tasks where precision, strength and reliability count.
