Tungaloy 6718539 Indexable Insert Drill 1 in 3xd

Product Description

The TUNGALOY 6718539 is a TDXU-FS series indexable insert drill designed for general-purpose drilling operations in metal cutting applications. Built from steel, the body accepts two XPMT-style inserts (size code 07H308) and delivers a 3xD depth-to-diameter ratio, making it a reliable choice for productive hole-making without the need for regrinding. The shank features a Weldon flat and flange interface for positive rotational drive in standard drill chucks and toolholders. Right-hand cutting geometry and through-coolant capability support consistent chip evacuation and extended insert life in production environments.

This drill is suited for drilling in steel, cast iron, and other common workpiece materials in both CNC machining center and lathe applications. The 3xD depth ratio and 1-inch nominal diameter make it appropriate for structural, die-mold, and general manufacturing contexts where a reliable indexable drilling solution is needed. The axial concentric and radial coolant entry system (code 3) supports both internal and external coolant delivery configurations. Install and operation are handled by machinists and CNC tooling technicians.

Compatibility

Compatible with XPMT-style inserts, specifically insert size code 07H308 (XPMT07H308, 0.2756 inches / 7.00 mm). Modular connection size is 1 inch. Body is designed for the TDXU-FS drill series.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and de-energize the machine spindle before mounting or changing inserts. Ensure the Weldon flat shank is fully seated and the set screw is properly engaged in the flat before operation. Verify coolant connections are clear and sealed before running the spindle at operating speed.
