Hertel 4006079 Indexable Insert Drill 13/16 in 2xd

Product Description

The HERTEL 4006079 is an indexable insert drill designed for high-productivity hole-making in metal cutting applications. It accepts two HPMT063306-GP inserts and is built around a 13/16 inch (0.8125 inch decimal) drill diameter with a maximum drill diameter of 0.8370 inches. The straight cylindrical shank measures 1 inch in diameter, making it compatible with standard drill chucks and tool holders of that bore size. The drill body is constructed of steel and features through-coolant capability, which is essential for chip evacuation and insert longevity during deep-hole operations. Right-hand cutting direction is standard.

This drill is suited for production and job-shop environments where consistent, repeatable hole sizing is required. The 2xD depth-to-diameter ratio supports a maximum drill depth of 1-5/8 inches, appropriate for through-holes and shallow blind-hole applications in ferrous and non-ferrous workpieces. It is installed and operated by machinists and tool room technicians working on CNC machining centers, manual lathes, and drill presses equipped with appropriate tool holding. Coolant supply through the shank end is threaded at 1/4 inch for direct machine coolant connection.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully powered down and locked out before mounting or removing the tool. Verify tool holder bore and retention system are rated for the 1 inch shank diameter before clamping. Connect the coolant supply to the 1/4 inch threaded shank-end port and confirm coolant flow before engaging the cut to protect insert edges and promote chip clearance.
