Featuring a spiral flute design, the E473 efficiently evacuates chips upwards, preventing clogging and ensuring smooth and continuous threading. This makes it particularly suitable for blind hole applications, providing precise and clean threads. The green ring denotes its specialised geometry for reduced torque and improved control, enhancing threading accuracy and efficiency. Crafted from high-speed steel with added cobalt (HSS-E-PM), this tap offers superior strength, durability, and heat resistance, making it ideal for threading tough materials such as alloy steels and stainless steels.
