Tungaloy 6771237 DMP163 Replaceable Drill Tip 16mm AH9130

Product Description

The TUNGALOY 6771237 is a replaceable drill tip in the DMP series, designed for indexable drilling systems that use a clamp-style insert seat. Built from solid carbide with a PVD-applied TiAlN coating, this tip carries the AH9130 manufacturer grade and targets demanding holemaking applications in steel, stainless steel, cast iron, and superalloys including titanium. The 140-degree point angle and regular helical spiral geometry support clean entry and chip evacuation across a range of workpiece materials. The tip seats into a 16mm insert seat and is installed by qualified machinists or tooling technicians as a consumable replacement in compatible DMP-series drill bodies.

This drill tip is suited for general drilling and holemaking in production and job-shop environments. It covers material grades P15, P35, M25, M35, K10, K25, S15, and S30, making it a practical choice when a single tip geometry must perform across mixed-material runs. The 16.00mm cutting diameter and 7.00mm flute length are appropriate for moderate-depth holes where rigidity and coating wear resistance are priorities. No coolant-through capability is present on this tip, so external or flood coolant should be accounted for in the setup.

Key Features

• Solid carbide construction with PVD TiAlN coating for wear and heat resistance
• AH9130 grade rated for steel, stainless steel, cast iron, and superalloys including titanium
• 140-degree point angle with standard point type and regular helical fluting
• 2-flute helical design promotes chip clearance during holemaking
• Clamp-style insert holding for secure seating in DMP-series drill bodies
• No coolant-through - compatible with external or flood coolant setups

Compatibility

Designed for use with DMP-series indexable drill bodies accepting a 16mm insert seat, ISO number DMP163. Confirm body and seat compatibility against TUNGALOY DMP series tooling documentation before ordering.

Installation Notes

Installation and tip replacement should be performed by a qualified machinist or tooling technician. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before handling or replacing the drill tip. Use the correct clamp torque driver and seating procedure specified in the tool body documentation - do not use improvised tools that may damage the seating surface or clamp. Inspect the insert seat for wear or debris before installing a new tip.
