Tungaloy America Inc. expands its DrillMeister exchangeable-head drill system by adding drill sleeves to the standard lineup to enhance drilling productivity of Swiss-type sliding-head automatic lathes.
DrillMeister is an exchangeable-head drill system that has the efficiency of solid carbide drills and the productivity of indexable drills. Covering a diameter range from 6.0 to 25.9 mm (0.236" to 1.020") in 0.1-mm (0.004") increments, the drill system features a high-precision drill body and head interface that is said to ensure precision and cutting point repeatability, while enabling for easy handling. DrillMeister offers five types of drill heads as standard, capable of addressing various drilling requirements.
Without drill sleeves, however, the use of DrillMeister drills in Swiss lathes are limited; the exchangeable-head drills can only be used when the drill shank fits the drill holder of the machine. New DrillMeister drill sleeves are available in 16, 25 and 32 mm diameters for metric sizes and 3/4" and 1" for imperial sizes that fit the drill holders of the same sizes equipped in Swiss lathes. They are said to make drill installation easy and also allow for quick changing of drill heads while remaining in the limited space of the Swiss lathe. Grill rigidity and index repeatability of each drill head is also guaranteed.

In addition, Tungaloy has added 48 new drill heads to its DMH drill head line of DrillMeister exchangeable drill head system, expanding its drill diameter range.
The DMH drill head features a fracture-resistant design that is suitable for applications that involve drilling holes through thin-walled sections of workpieces. In normal circumstances, thin walls tend to spring back on the drill after the drill pierces through and exits the hole. In the process, uncut material shifts and forms exit burrs that impose extra burdens on the drill edge. These problems inflict damage on drill corners, shortening tool life. The DMH drill head’s geometry protects drill corners from fracture damage, providing extended tool life and reduced downtime.
With the new drill heads in the line, DrillMeister can now address more extensive hole size requirements.
