Tungaloy 5568911 Carbide Replaceable Tip Drill 21/32 in

Product Description

The TUNGALOY 5568911 is a solid carbide replaceable tip drill in the DrillMeister DMP series, designed for general holemaking in a wide range of workpiece materials. It features a 16.67mm (21/32 inch) cutting diameter with a TiAlN PVD coating applied to AH725-grade solid carbide. The 140-degree drill point angle and X-thinned web geometry reduce entry force and improve centering accuracy. With a helical, regular-spiral flute design and clamp-style tip retention, this drill delivers consistent hole quality in production environments. Machinists and tooling specialists install this style of tip on compatible DrillMeister DMP-series drill bodies.

This replaceable tip is suited for general drilling and holemaking operations in steel, stainless steel, cast iron, and superalloys including titanium. It targets applications across ISO material grades P15, P30, M15, M30, K25, K30, S15, S25, and S25, making it a versatile option for job shops and production machining environments handling mixed-material workloads. The tip seats into Insert Seat Size 16 DMP-series holders and is identified by ISO number DMP1666.

Installation Notes

Installation is performed by machinists or tooling technicians following the machine tool builder and TUNGALOY DrillMeister body instructions. Ensure the spindle is powered down and the machine is in a safe state before seating or removing the tip. Use the correct torque tool specified by the drill body manufacturer for the clamp screw - do not overtighten or substitute fasteners. Inspect the insert seat for chips or debris before each tip change to protect seat integrity and maintain runout tolerances.
