Hertel 4006094 Indexable Insert Drill 1-5/8 in 2xd

Product Description

The HERTEL 4006094 is a straight-shank indexable insert drill designed for high-productivity hole-making in metal cutting applications. Built on a steel body, this drill accepts two HPMT125812-GP inserts and delivers a maximum drill depth of 3.25 inches at a 2xD depth-to-diameter ratio. The cutting diameter is 1.625 inches (41.28 mm), with a straight cylindrical shank diameter of 1.5 inches. Right-hand cutting geometry and through-coolant capability via a 0.25-inch threaded shank-end port make this drill suited for CNC machining centers and turning centers where chip evacuation and tool life are critical. A licensed machinist or tooling technician typically handles setup and insert indexing.

This indexable insert drill is intended for use in production machining environments where consistent bore quality and repeatable positioning are required. It fits spindles and tool holders accepting a 1.5-inch straight cylindrical shank. The 2xD ratio makes it a practical choice for through-holes and blind holes in steel, cast iron, and similar ferrous workpiece materials on horizontal or vertical machining centers. The collar diameter of 1.949 inches provides a positive register surface for depth or holder contact.

Key Features

• Indexable insert design takes 2 HPMT125812-GP inserts for fast, in-machine changeovers
• Through-coolant capable with a 1/4-inch threaded coolant hole at the shank end
• Right-hand cutting direction for standard spindle rotation
• 2xD depth-to-diameter ratio with 3.25-inch maximum drill depth
• Straight cylindrical shank at 1.5 inches diameter for broad holder compatibility
• Steel body construction for rigidity under interrupted and continuous cutting loads

Compatibility

Compatible with tool holders accepting a 1.5-inch straight cylindrical shank. Takes HPMT125812-GP indexable inserts. Designed for use in the HID drill style system.

Installation Notes

Installation and insert indexing should be performed by a qualified machinist or tooling technician. Power down and lock out the spindle before changing inserts or mounting the drill body in the holder. Confirm clamping torque on insert screws and holder set screws according to the tool holder and insert manufacturer specifications before running the spindle. Verify coolant port alignment if through-spindle coolant is used.
