High Performance Mold and Die Steel Products

In cooperation with International Mold Steel Inc. of Florence Kentucky, Titus Steel offers a full range of sizes of all premium mold and die steel products. We also offer blanchard grinding and six-side milling.

Blanchard grinding is a precision machining process used to achieve flatness and parallelism on large, flat metal surfaces by removing material through the use of rotary surface grinders.

Six-side milling is a machining process that involves the removal of material from all six sides of a workpiece to achieve precise dimensions and surface finishes.
