Tungaloy 6863101 Replaceable Drill Tip DMP186 AH725

Product Description

The TUNGALOY 6863101 is a replaceable carbide drill tip from the Drill Meister series, designed for indexed drilling applications in high-production machining environments. Carrying the DMP186 geometry designation and manufactured in grade AH725 with a TiAlN coating, this insert tip fits an 18 mm insert seat and delivers a cutting diameter of 0.7320 inches (18.60 mm). The 140-degree drill point angle promotes self-centering entry and clean chip formation across a broad range of workpiece materials. Installation and replacement are handled by machinists and toolroom technicians without removing the drill body from the spindle.

This replaceable tip is suited for drilling operations in steel, stainless steel, cast iron, superalloys, and titanium, covering ISO material groups P, M, K, and S. The Drill Meister platform is commonly used in CNC machining centers and turning centers where frequent tip changes are required to maintain consistent hole quality and tolerance. The AH725 grade with TiAlN coating supports elevated cutting speeds and extended tool life in demanding production environments including aerospace and general metalworking.

Installation Notes

Replaceable drill tips of this type are installed and torqued by machinists using the manufacturer-specified wrench supplied with the drill body system. Always power down and lock out the machine spindle before tip replacement. Do not force the tip into the seat or use impact tools, as carbide tips are brittle and susceptible to edge damage. Verify tip seating and clamp integrity before resuming cutting operations.
