Originally titled 'Spiral Flute and Tap Series Designed for Nickel Alloys'
OSG Tap & Die’s Exopro-WHR-Ni spiral flute and spiral point tap series is designed to excel in nickel-based alloy applications. The nickel-based heat resistant alloys are materials with poor machinability. Short tool life, sudden tool wear, breakage and chipping at the chamfer are common problems associated with the machining of these materials.
In order to accommodate industry demand, Exopro-WHR-Ni tap series 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 company says. The spiral point tap, designed for blind hole applications, features a rake angle to protect against sudden tool wear. With the addition of OSG’s HR coating, tool life can be substantially prolonged versus the competition.
