Tungaloy 6863054 Replaceable Drill Tip 0.5470in DMP139 AH725

Product Description

The TUNGALOY 6863054 is a replaceable drill tip designed for use with the Drill Meister modular drilling system. Manufactured from solid carbide with a TiAlN coating and produced to the AH725 grade, this tip delivers consistent cutting performance in demanding applications. It features a DMP139 insert geometry with a 140-degree drill point angle and a 13.90 mm (0.5470 inches) cutting diameter. The tip weighs approximately 0.026 pounds. Certified to AS 9100, ISO 14001, and ISO 9001:2008 standards, it is suited for production environments where dimensional accuracy and tool reliability are critical. Machinists and tooling technicians are the primary installers.

This drill tip is intended for use on steel, stainless steel, cast iron, superalloys, and titanium workpieces, covering ISO material groups P, M, K, and S. It is well suited for both production machining centers and manual milling operations where a modular, replaceable-tip drill system is in use. The DMP insert geometry and AH725 carbide grade are engineered to handle the elevated cutting forces and heat generated when drilling difficult-to-machine alloys and ferrous materials. The insert seat size is 13, corresponding to the matching Drill Meister holder body.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Before changing the drill tip, ensure the machine spindle is fully stopped and locked out per facility lockout/tagout procedures. Use the appropriate Drill Meister wrench or torque tool as specified by the holder manufacturer - do not apply excessive force during tip seating. Inspect the holder seat for chips or debris before installing a new tip to ensure proper seating and concentricity.
