Walter has introduced the Walter Titex DB133 Supreme, a solid carbide micro drill that is designed to deliver tight tolerances, high quality surface finishes, superior process reliability and longer tool life. The differences in the DB133 Supreme begin with the use of grades WJ30EL and WJ30ER, developed by Walter specifically for micro drills. These grades provide the drills with superior wear resistance.

ln addition, Walter's new geometry increases the process reliability of these new drills, and optimized dimensions allow for maximum stability, even with the smallest drills. The uniform finish on the drill cutting edge and tight tolerances ensures excellent workpiece surface finishes. With the Walter Titex DB133 Supreme special geometry, chip removal is effective, even without through coolant. This allows hole depths of up to 8xDc to be easily achieved. Taken together, these design features give the Walter Titex DB133 Supreme 20 percent higher cutting data than its nearest competitor.

The new solid carbide micro drills, with their 140° point geometry, can be used universally on many different materials in ISO material groups P, K and N. Diameters range from 0.02 to 0.12 in (0.5 to 2.95 mm). This new drill design is ideal for users in general machining, mold and die making, the energy and automotive industries and any other areas where small diameter, deep holes, are required.
