Drill Insert handles ductile materials.

Press Release Summary:



Unidrill® has UC-CCR chipbreaking geometry, suitable for drilling ductile materials such as steels, stainless steels, and cast irons in range of 0.531 to 1.000 in. dia. Corner radius reduces thermal stress, improves tool life, minimizes break-out at back of hole, and improves surface finish. Clamping system ensures precise insert location, while SC7052 CVD coating allows high feed rates at low speeds for less rigid applications and deeper holes.

Drill Insert Product Sheet Details Stellram's New Chipbreaking Geometry for Optimum Chip Control


La Vergne, TN-Stellram's product sheet for UC-CCR geometry for Unidrill® features patented chipbreaking geometry which is ideal for drilling ductile materials such as steels, stainless steels and cast irons in a diameter range from 0.531" to 1.000".

The corner radius reduces thermal stress, improves tool life, minimizes break-out at the back of the hole and improves surface finish. The patented clamping system assures precise insert location.

A new CVD coating (SC7052) allows high feed rates at low speeds for less rigid applications and deeper holes.

The product sheet also lists the advantages of UC-CCR geometry, cutting conditions for SC7052 and UC-CCR stock availability.

Stellram is a globally integrated technological leader in the development of metalcutting answers for turning, milling, threading, drilling and grooving applications.
