Tungaloy 4800301 Indexable Drill Insert LOGT06NDJ AH725

Product Description

The TUNGALOY 4800301 is a solid carbide indexable drill insert carrying the LOGT06NDJ geometry and AH725 manufacturer grade. It features a PVD-applied TiAlN coating engineered to extend tool life when drilling steel, stainless steel, cast iron, superalloys, and titanium. The insert measures 0.236 inches inscribed circle and 0.079 inches thick, with a 0.0157-inch corner radius and a 100-degree included angle. The NDJ chipbreaker geometry promotes controlled chip evacuation during deep-hole drilling operations. This insert is installed by machinists and tooling technicians working with indexable drill bodies in production and job-shop environments.

This insert is suited for indexable drilling applications across a broad range of workpiece materials including carbon steel, stainless steel, cast iron, superalloys, and titanium alloys. The right-hand cutting configuration and LOGT insert style position it for use in standard LOGT-series indexable drill bodies. It is appropriate for both light-production and high-volume CNC drilling operations where consistent insert geometry and coating performance are required across repeated tool changes.

Key Features

• AH725 carbide grade with PVD TiAlN coating for wear resistance on hard and abrasive workpiece materials
• NDJ chipbreaker promotes chip control and reduces built-up edge in interrupted and continuous cuts
• 0.236-inch inscribed circle with 100-degree proprietary included angle for LOGT-series drill bodies
• 0.0157-inch corner radius reduces stress concentration at cutting edge entry and exit
• Right-hand cutting orientation for standard CNC drilling and machine-tool spindle compatibility
• Insert Size Code 06 for precise seating and repeatable edge positioning in the insert pocket

Compatibility

Designed as a direct-fit replacement insert for LOGT-series indexable drill bodies accepting LOGT06 insert size code with right-hand cutting geometry.

Installation Notes

Installation is performed by a machinist or tooling technician. Always power down and lock out the machine spindle before seating or replacing inserts. Use the manufacturer-specified torx or hex key to secure the insert clamp screw, and inspect the insert pocket for debris or damage before installation. Follow the drill body manufacturer's torque guidance for the clamping screw and verify edge runout after seating.
