Extension Tap 1 -8 Cobalt MPN:1625518258
Extension Tap 1 -8 Cobalt
A powerful, cobalt extension tap for heavy duty machining and threading tasks that require extra strength and durability to cut through tough metals such as stainless steel or cast iron in machine shops, tool & die industries, automotive/truck mechanics, or heavy equipment maintenance facilities for skilled technicians seeking precision performance to complete demanding jobs.
The TiCN coating on these taps protects them from wear and is harder and more wear-resistant than a TiN coating. High-performance taps are harder and more wear-resistant than high-speed steel taps. They provide good precision and accuracy in threading tasks. Thread-forming taps press against the sides of a hole to form threads as they are rotated into the hole. They don't produce chips, which eliminates the need to clear chips from the hole and prevents threads from being deformed during tapping.
