Tong dies have come a long way since tongs became commonplace in the oilfields. Eckel has been at the forefront of this developing technology with the development of larger wrap-around type dies for many of its tong models. We offer coarse tooth design and fine tooth design depending on the application.

Eckel offers contour type dies for tubing sizes on many of our tongs which use pivot heads. In addition to our contour dies, we provide A and S series wrap-around dies for our 133/8 and 20 Standard casing tongs, providing a larger gripping area and reducing pipe damage. Rig type dies are used extensively for 4-inches and above. Sliding heads with rig dies is the best choice when running drill pipe connections.

The Eckel Sliding head biting system utilizes our wide angle wraparound type dies and is considered the best choice of power tong biting systems for use on small tubulars. The biting surface of each wrap-around die is symmetrically spaced 180-degress apart from each other at all times. This biting system provides a larger range of tubular coverage and allows for more die teeth to come in contact with the tubular while preventing it from moving off center and insuring an equally distributed load on the tubular connection.

        The lower-penetration die (pyramid fine tooth) is a better choice.
