Item #: 14419444
Brand: Seco
Model #: 10001098
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.
Uncoated tools do not feature supportive treatments on the cutting edge. They are are used at reduced speeds for general applications on nonferrous metals.
Slow Spiral Flutes with 8-20 degree angles are used for tough materials like high nickel alloys, titanium and some series of stainless steels.
