In response to increased industry demands for precision, Walter USA LLC has expanded its high-performance line of Titex X-treme DM micro drills with the addition of products in the 16xD and 30xD drilling depth ranges. In addition, diameters of 2 to 2.95mm are now available for all drilling depths in these product ranges. Formerly the 2mm diameter was available only in sizes smaller than 25xD.

Whether automotive, aerospace, die and mold, or general metalworking, industries increasingly require a multitude of drilled holes with diameters smaller than 3mm. Sometimes drilling depths of up to and over 30xD are required. Typical applications include drilled holes for lubrication, cooling, venting, and nozzle bores.

Walter has reportedly succeeded in bringing the superior performance of its Titex X-treme DM family into the micro drill range due to a series of features that are typically not found in small diameter drills. First, these new Walter micro drills have internal cooling, just like the larger members of the X-treme family. Furthermore, their optimized point geometry with special cutting edge preparation and precisely dimensioned flute geometry ensure superior chip formation and, therefore, very high process reliability. The polished surface of the flutes also supports excellent chip evacuation.

The X-treme DM micro drills have a wide field of application, including the P, K, M and N ISO material groups. Importantly, the new DM micro drills allow the drilling process to take place without pecking. Pecking would cause additional load change and make the process unsafe.
