Tungaloy 6863040 Replaceable Drill Tip 0.4920 in AH725

Product Description

The TUNGALOY 6863040 is a replaceable drill tip from the Drill Meister series, designed for use with compatible indexable drill bodies in demanding metal-cutting operations. Built from solid carbide with a TiAlN coating and TUNGALOY AH725 grade, this tip delivers consistent cutting performance across a range of ferrous and exotic workpiece materials. The 0.4920-inch cutting diameter and DMP insert geometry with a 140-degree drill point angle make it well-suited for high-precision hole-making in production environments. Installation and replacement are handled without removing the drill body from the machine, reducing changeover time on the floor.

This drill tip is intended for use in CNC machining centers and drill presses where consistent hole quality in steel, stainless steel, cast iron, superalloys, and titanium alloys is required. The DMP125 geometry with ISO insert seat size 12 positions it for mid-range diameter drilling applications in aerospace, general manufacturing, and heavy industrial settings. It is installed by qualified machinists and tooling technicians familiar with indexable tooling systems. Minimum order quantity is 2 units; package quantity is 1.

• Solid carbide construction with TiAlN coating for heat and wear resistance
• AH725 manufacturer grade optimized for steel, stainless steel, cast iron, superalloys, and titanium
• 140-degree drill point angle suits general-purpose hole entry in hard materials
• DMP insert geometry with ISO seat size 12 for precise seating in compatible drill bodies
• Meets AS 9100, ISO 14001, and ISO 9001:2008 quality and environmental standards
• Replaceable tip design allows fast changeover without removing the drill body from the spindle

Compatibility

Designed for use with Drill Meister series drill bodies accepting DMP geometry inserts at ISO insert seat size 12 and a 0.4920-inch tip diameter.

Installation Notes

Replaceable drill tips should be installed by a qualified machinist or tooling technician following the drill body manufacturer's torque and seating procedures. Ensure the spindle is fully stopped and the machine is locked out before handling or replacing the tip. Inspect the insert seat for chips or contamination before seating the new tip. Do not force the tip into the seat; proper engagement should require only the specified wrench and manufacturer-recommended installation torque.
