Tungaloy 6863028 Replaceable Drill Tip 0.4450 in DMP113

Product Description

The TUNGALOY 6863028 is a replaceable drill tip from the Drill Meister series, designed for use with compatible indexable drill bodies in metal-cutting operations. Built from solid carbide with a TiAlN coating and manufactured to grade AH725, this tip delivers consistent cutting performance across a range of demanding workpiece materials. The 140-degree drill point angle and DMP insert geometry are suited for productive, accurate hole-making in production environments. At 0.4450 inches (11.30 mm) cutting diameter, it fits insert seat size 11 Drill Meister holders. Licensed machinists and CNC operators in job shops and manufacturing facilities are the primary users.

This drill tip is intended for machining steel, stainless steel, cast iron, superalloys, and titanium - covering ISO material groups P, M, K, and S. It is well suited to high-volume drilling applications on CNC machining centers and lathes where tip replacement in the field is preferred over regrinding. The AH725 grade with TiAlN coating supports elevated cutting speeds and provides wear resistance across these material categories. No through-coolant is available with this tip; flood coolant or air blast is the appropriate cooling method for this configuration.

Compatibility

Designed for use with Drill Meister series indexable drill holders accepting DMP insert geometry at insert seat size 11. Confirm holder compatibility using the ISO number DMP113 and seat size 11 before ordering.

Installation Notes

Installation is performed by machinists or CNC operators; power down and lock out the machine spindle before seating or removing any drill tip. Use the correct Torx or insert-key wrench specified by the toolholder manufacturer - do not use substitutes that may damage the seating surfaces. Inspect the insert pocket and seating surfaces for chips or wear before installing a new tip. Follow the toolholder manufacturer's clamping procedure to ensure the tip is fully seated and secure prior to cutting.
