Tungaloy 6863026 Replaceable Drill Tip 0.4370 in AH725

Product Description

The TUNGALOY 6863026 is a solid carbide replaceable drill tip engineered for use in the Drill Meister modular drilling system. Carrying the DMP111 insert geometry and AH725 grade with a TiAlN coating, this tip delivers consistent cutting performance across demanding workpiece materials. The cutting diameter measures 0.4370 inches (11.10 mm), and the 140-degree drill point angle suits general-purpose hole-making in steel, stainless steel, cast iron, superalloys, and titanium. Licensed machinists and toolroom technicians install this tip as part of a quick-change boring and drilling setup, reducing downtime when tips dull or chip without replacing the full drill body.

This replaceable tip is intended for use in machining environments where material versatility and rapid tip exchange are priorities. The AH725 grade with TiAlN coating is well-suited for interrupted cuts and variable-hardness workpieces common in aerospace, general metalworking, and heavy manufacturing. The DMP111 geometry and insert seat size 11 position this tip within the Drill Meister product family for modular drill bodies accepting that seat designation. It is appropriate for both CNC machining centers and manual toolroom drilling applications where consistent hole geometry is required.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians following standard modular drill tip replacement procedures. The drill body and spindle must be fully stopped and the machine powered down before removing or seating the replaceable tip. Use the manufacturer-specified torque wrench or key to secure the tip to the drill body - do not overtighten by hand. Verify tip seating and runout with a dial indicator before resuming production cuts.
