Hertel 4006132 Indexable Insert Drill 1-3/4 in 4xd

Product Description

The HERTEL 4006132 is a straight-shank indexable insert drill designed for high-productivity hole-making in metal components. It accepts two HPMT125812-GP inserts and drills to a maximum depth of 7 inches at a 4xD depth-to-diameter ratio. The drill body measures 1-3/4 inches in diameter with a 1-1/2 inch straight-cylindrical shank, and the tool body is constructed from steel. Coolant-through capability is built in via a 1/4 inch shank-end coolant hole thread, supporting extended tool life and chip evacuation in deep-hole applications. This drill is intended for installation and use by machinists and toolroom technicians working on CNC machining centers and manual drilling equipment.

The 4006132 is suited for production drilling operations in ferrous and non-ferrous materials where indexable insert tooling is preferred over solid-carbide or brazed-tip alternatives. The 4xD ratio makes it appropriate for medium-depth bores in structural components, fixtures, and machined housings. The right-hand cutting direction is standard for conventional spindle rotation. Coolant-through delivery helps maintain cutting temperatures and flush chips from the hole during continuous or interrupted cuts.

Installation Notes

Installation and setup should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and locked out before inserting or removing the drill body. Confirm insert seating and screw torque per the insert manufacturer specification before initiating a cut. Engage coolant-through supply if available to maximize chip evacuation and insert life during deep-hole drilling.
