Large-Diameter Drills Mount without Removing Tool from Spindle

Tungaloy has expanded its DrillForce-Meister series of interchangeable-tip drills. These tools, designed for large-diameter hole making from 26.0 to 41.0 mm, feature two effective cutting edges for high speed and productivity. DrillForce-Meister’s clamping system uses an error-proof asymmetric seat and a screw setting, which speeds head replacement. Since a new drill head can be mounted without removing the drill body from the spindle, the full resetting and re-indexing process is eliminated, shortening tool-change time. By replacing the head screw regularly, the drill body can be used for an even longer period, reducing tooling cost and inventory requirements, the company says.

The drill head is supported by a wide contact area on the seat so that the drill can withstand the high cutting force generated during high-feed drilling. The insert seat is designed with precision, ensuring repeatability and minimizing runout, while the cutting edge is prepared to increase coating adhesion of the reliable AH725 grade.
