OSG Tap & Die Inc. introduced the EXOPRO-WHR-Ni spiral flute and spiral point tap series, designed to excel in nickel-based alloy applications.

Nickel-based heat resistant alloys are materials with extremely poor machinability. Short tool life, sudden tool wear, breakage and chipping at the chamfer are common problems associated with the machining of these materials. To accommodate new industry demand, OSG has developed a total solution for threading nickel alloys with the EXOPRO-WHR-Ni tap series.

The EXOPRO-WHR-Ni spiral flute tap features a new point flute design to improve cutting edge rigidity, which helps prevent chipping and enables it to excel even in blind holes.

The EXOPRO-WHR-Ni spiral point tap, designed for blind hole applications, features a unique rake angle to protect against sudden tool wear. With the addition of OSG's patented HR coating, tool life can be substantially prolonged, according to the company.
