Iwaki, October 2022—Tungaloy has expanded its DrillMeister exchangeable-head drill system by adding drill sleeves to the standard lineup to enhance drilling productivities of Swiss-type sliding head automatic lathes.
DrillMeister is an innovative exchangeable head drill system that has both the efficiency of solid carbide drills and the productivity of indexable drills. Covering the diameter range from 6.0 to 25.9 millimeters (.236 to 1.020 inches) in 0.1 millimeter (.004 inch) increments, the drill system features a high precision drill body and head interface that ensures precision and cutting point repeatability, while allowing 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. Otherwise, DrillMeister drills have no place in drilling applications performed in Swiss lathes, not being able to bring out a full potential and benefits of modular drills in Swiss style machining.
The new DrillMeister drill sleeves are available in 16, 25, and 32 millimeters in diameters for metric sizes and 3/4 inches and one inch for imperial sizes that fit the drill holders of the same sizes equipped in Swiss lathes. All drill sleeves have a threaded connecting port on the sleeve end for easy coolant hose connection.
The product of simple design and engineering technology, the new DrillMeister drill sleeves not only make the drill installation easy but also allow quick changing of drill heads while remaining in the limited space of the Swiss lathe, significantly reducing machine downtime when compared with solid carbide drills. Also, thanks to the exchangeable-head system, DrillMeister eliminates the need and cost of regrinding, while its unique interlocking design with precision interface guarantees drill rigidity and index repeatability of each drill head. This ensures high performance and tool life predictability, while also reducing the number of drills needed in inventory.
