Exact Tooling IR#: 04

Features and Benefits

Plug chamfers are the most commonly used chamfer and are designed for efficiently threading through and blind holes. They have 3 to 5 threads.
Powdered Metal (PM) is tougher and more cost effective than solid carbide. It is commonly used on highly abrasive materials including high silicon aluminums.
TiCN/TiN is a multi-layered coating designed to increase tool life. It is commonly used at high cutting speeds for smoothing and finishing of the workpiece.
Slow Spiral Flutes with 8-20 degree angles are used for tough materials like high nickel alloys, titanium and some series of stainless steels.

OSG - 1/2-13 UNC 4 Flute 2B Modified Bottoming Spiral Flute Tap - Vanadium High Speed Steel, Oxide Finish, 110mm OAL, Right Hand Flute, Right Hand Thread, Series 13025


Item #: 68571553
Brand: OSG
Model #: 1302502601
Exact Tooling IR#: 04

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.
Vanadium High Speed Steel (HSSE) is made of high speed steel, carbon, vanadium carbide and other alloys to increase abrasive wear resistance and toughness. It is commonly used in general applications on stainless steels and high silicon aluminums.
Oxide, also known as black oxide or steam oxide, is a surface treatment that prevents chip building, galling and welding on the workpiece. It is commonly used on low carbons, stainless steel and ferrous metals.
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.
