Dormer E473 HSS-E-PM Green Ring Shark Spiral Flute Tap

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.
