Conical countersink fi 30 mm 90 degrees DIN 335 C HSSE is a high-end tool designed for precision countersinking of holes in metal materials. Compliant with DIN 335 C, it is equipped with three symmetrically placed blades, which provide excellent stability during operation, resulting in an even finish of the machined surface and minimized risk of vibration.
The use of a conical countersink fi 30 mm 90 degrees for stainless steel guarantees effective processing of hard-to-machine materials such as austenitic steels, brass, bronze or aluminum alloys. Being made of HSSE high-speed steel with added cobalt, the tool is characterized by increased wear resistance and long service life even under high heat loads.
Thehigh-quality cutting surface makes it possible to achieve smooth countersinks for countersunk screw heads and face machining of holes. The solid cylindrical shank allows for secure clamping in the chuck and safe guidance of the tool in the automatic or manual cycle.
- Increased durability - thanks to the use of HSSE cobalt steel, the tool works steadily and longer than standard countersinks.
- Three working blades - ensure smooth and precise operation without run-out effect, which improves the quality of the workpiece.
- High quality finish - perfectly smooth countersinks, ready for fastener installation.
- Versatility of applications - works well in both automatic CNC machining and manual work.
- Ideal for non-ferrous metals and stainless steels - keeping hole edges clean and even.
Conical countersink fi 30 mm 90 degrees is an indispensable tool in any professional tool room, guaranteeing repeatability and quality of details that will meet the highest technological requirements.
