Tungaloy 6863066 Replaceable Drill Tip 0.5940 in AH725

Product Description

The TUNGALOY 6863066 is a replaceable drill tip from the Drill Meister series, designed for use in modular drilling tool systems. This solid carbide insert features a DMP insert geometry with a 140-degree drill point angle and a TiAlN coating, making it well suited for high-productivity hole-making in demanding materials. The AH725 grade carbide provides wear resistance across a range of workpiece materials. With a cutting diameter of 0.5940 inches (15.10 mm) and an insert seat size of 15, this tip indexes quickly into compatible Drill Meister bodies, reducing downtime during production runs. Licensed machinists and CNC operators handling precision drilling applications are the primary users.

This replaceable drill tip is engineered for machining steel, stainless steel, cast iron, superalloys, and titanium, covering ISO material codes P, M, K, and S. It fits into compatible Drill Meister modular drill bodies used in CNC turning centers and machining centers in both job shop and production environments. The DMP151 ISO designation and seat size 15 allow straightforward identification of the matching drill body. No coolant-through capability is present on this tip, so external coolant or flood coolant setups should be planned accordingly.

Key Features

• Solid carbide construction with AH725 grade for extended tool life in hard and abrasive workpiece materials
• TiAlN coating improves heat and oxidation resistance during high-speed drilling
• 140-degree drill point angle reduces thrust force and improves self-centering on entry
• DMP insert geometry and seat size 15 enable fast, repeatable tip indexing
• Covers four ISO material groups: P (steel), M (stainless steel), K (cast iron), S (superalloys and titanium)
• Manufactured to AS 9100, ISO 14001, and ISO 9001:2008 quality standards

Compatibility

Designed for use with Drill Meister modular drill bodies accepting DMP-geometry replaceable tips at seat size 15 with a 15.10 mm cutting diameter. Verify the matching drill body designation before ordering.

Installation Notes

Replaceable drill tip installation should be performed by a qualified machinist with the spindle powered down and the machine in a locked-out, tagged-out state. Use the torque wrench or clamping tool specified by the drill body manufacturer for the Drill Meister system to seat the tip correctly. Inspect the insert pocket and seating surfaces for chips or contamination before installing a new tip. Do not use worn or damaged insert seats, as improper seating can cause tip ejection and workpiece damage.
