Emuge - 1/4-28 UNF 3 Flute 3B Bottoming Spiral Flute Tap - Cobalt, TiN Finish, 2-1/2" OAL, Right Hand Flute, Right Hand Thread, Series Enorm


Item #: 52290434
Brand: Emuge
Model #: AU513710.5043
Exact Tooling IR#: 04

Features and Benefits

Bottoming chamfers are used for threading blind holes. They have 1 to 2 threads.
Cobalt is harder than high speed steel and provides better wear resistance. It is commonly used on high tensile alloys.
Titanium Nitride (TiN) is a multi-purpose coating which increases chip flow in softer materials. The heat and hardness resistance allows the tool to run at higher speeds than uncoated tools.
Fast Spiral Flutes with 40-53 degree angles are suitable for ductile materials like aluminum and copper; medium to high carbon steels and free machining stainless steels.

Features and Benefits

Modified bottoming chamfers are similar to bottoming chamfers, but they are longer and have more teeth. They are used for threading blind holes and have 2 to 2-1/2 threads.
