Countersink Ø8.3 mm 90° DIN 335 C HSS is a specialized cutting tool designed for precise hole machining at an angle of ninety °. Made from HSS high-speed steel in accordance with DIN 335 C, it provides high resistance to heat and dynamic loads during intensive operation.
The tool is equipped with 3 cutting edges, which effectively stabilize the cutting process, minimizing vibration and ensuring an excellent surface finish. This enables high dimensional repeatability and smoothness, resulting in higher machining quality and less frequent tool replacement.
Countersink for metal is ideal for countersinking holes for countersunk screws, deburring, and leveling end faces. The product is suitable for working with a variety of materials, from unalloyed steels to nonferrous metals, and is particularly recommended as Ø8.3 mm 90° countersink for stainless steel, where high surface quality is essential.
The tool can be used on conventional machine tools, benchtop drill presses, and modern CNC machining centers. High-quality surface of the countersink reduces material adhesion and supports effective chip evacuation.
- Stable tool operation – the three-edge design minimizes vibration and improves end-face surface quality.
- High wear resistance – HSS steel ensures durability when working with metals and stainless steel.
- Universal application – ideal for countersinking, chamfering, and deburring various materials.
- DIN 335 C standard – ensures full compliance with industrial technical requirements.
Ø8.3 mm 90° countersink is a reliable choice for professionals who require high precision and long tool life.
