Specifications:-Cutting Edge Diameter: 18.5mm-Shank Diameter: 1/2 inch-Cutting Edge Length: 3.2 inch-Total Length: 6 inch-Split Point: 118°-Material: 4341 high-speed steel1. The 4341 high-speed steel material typically exhibits superior corrosion resistance and higher strength, making it suitable for operation under high-temperature conditions. Its heat resistance allows for the manufacture of cutting tools that require higher performance. Additionally, the nitrided layer provides oxidation and corrosion resistance, thereby extending the tool's lifespan.2. 118° Conventional Point, not easy to slide, suitable for wood, plastic soft metal, and other materials drilling, widely used in daily operation, more appropriate for home and light industry use, simple operation, strong adaptability.3.
