Tapered countersink fi 40 mm 120 degrees DIN 347 C HSS is a high-performance cutting tool designed for professional face machining and hole enlargement. Thanks to the use of three precision-ground blades, the tool guarantees excellent stability during operation, which translates into even cutting and higher quality surface finish.
The conical countersink fi 40 mm 120 degrees is made of HSS (High Speed Steel), characterized by very good resistance to wear and high temperatures, reaching up to six hundred degrees Celsius. The tool is ideal for working with materials such as stainless steel, unalloyed steel, non-ferrous metals, metal alloys or plastics.
The high-quality work surface facilitates chip evacuation and reduces workpiece adhesion, which increases machining efficiency and tool life. Thanks to its design and compliance with DIN 347 C, the metal taper countersink is suitable for both conventional drills and modern CNC machines.
- Three blades for stable and precise operation - reduces vibration and improves surface quality.
- HSS high-speed steel - guarantees durability and abrasion resistance when working at high temperatures.
- Universal application - for machining stainless steel, metals and plastics on conventional and CNC machines.
- Surface with high quality finish - increases process efficiency and tool life.
The conical countersink fi 40 mm 120 degrees for stainless steel is a reliable tool for workshops and factories that value quality, durability and efficiency in machining.
