The 2-459866-4 is a high-performance crimp tool engineered to produce reliable electrical terminations with precise dimensional control. It is manufactured from high-quality tool steels chosen for toughness and wear resistance, featuring critical surface hardness above Rc 55 and a surface finish of 8 micro-inches or less. The crimper surfaces are treated with a hard chromium plating (Rc 65+) which provides a low coefficient of friction and high resistance to adhesive wear and material buildup. This design ensures consistent crimp form, reduces process variation during production, and extends the service life of the tool, making it ideal for high-volume manufacturing applications requiring repeatable quality.
