Hertel 4006159 Indexable Insert Drill 1-1/4 in 2xd

Product Description

The HERTEL 4006159 is a straight-shank indexable insert drill designed for high-productivity hole-making in metal cutting applications. Built to a 2xD depth-to-diameter ratio, it drills to a maximum depth of 2.5 inches at a diameter of 1.25 inches (31.75 mm). The body is constructed of steel and accepts two HPMT094508-GP inserts for fast, repeatable cutting without regrinding. Coolant-through capability via a 1/4-inch threaded coolant hole at the shank end keeps the cutting zone clear and extends insert life. This tool is intended for use by machining professionals on CNC lathes, machining centers, and manual mills equipped with appropriate tool holders.

This drill suits production and job-shop environments where consistent hole diameter and depth control are required in ferrous and non-ferrous materials. With a straight-cylindrical shank diameter of 1.25 inches and a body length of 6.484 inches, it fits standard tooling blocks and hydraulic or mechanical chuck holders. Right-hand cutting direction makes it compatible with standard spindle rotation. It is well-suited to roughing and semi-finish drilling cycles where indexable insert tooling reduces toolchange downtime compared to solid carbide alternatives.

Compatibility

Compatible drill style is HID. Takes HPMT094508-GP inserts. Fits tool holders designed for a 1.25-inch straight-cylindrical shank. Verify holder bore and retention method before mounting.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and locked out before mounting or dismounting the drill body. Secure the shank in a properly rated tool holder torqued to the holder manufacturer's specification. Connect coolant supply to the shank-end port before running at operating speed to prevent premature insert wear.
