Hertel 4006142 Indexable Insert Drill 1-5/8 in 3xd

Product Description

The HERTEL 4006142 is a straight-shank indexable insert drill designed for high-productivity hole-making in metalworking applications. Built with a steel body and a 3xD depth-to-diameter ratio, it drills to a maximum depth of 4-7/8 inches with a 1-5/8 inch (1.6250 inch decimal) cutting diameter. The drill accepts two indexable inserts compatible with the HPMT125812-GP insert style and features through-tool coolant delivery via a 1/4 inch shank-end coolant hole thread. Cutting direction is right-hand. This tool is intended for use by machinists and toolroom professionals on CNC machining centers and drill presses equipped for indexable tooling.

The 4006142 is suited for production drilling in steel and similar ferrous materials where a high-volume, repeatable hole is required. The straight-cylindrical shank measures 1-1/2 inches in diameter with a 3.0000 inch shank length, making it compatible with standard toolholders and drill chucks of that bore size. The 9.2530 inch body length accommodates setups where extended reach or fixture clearance is needed. This drill is typically deployed in job shop and production environments handling medium-to-large bore diameter work.

Installation Notes

Installation should be performed by a qualified machinist familiar with indexable tooling systems.
