Hertel 4006119 Indexable Insert Drill 1-1/16 in 3xd

Product Description

The HERTEL 4006119 is a steel-body indexable insert drill designed for high-productivity hole-making in metal cutting applications. With a nominal drill diameter of 1-1/16 inches (1.0625 inches decimal) and a maximum drill depth of 3-3/16 inches at a 3xD depth-to-diameter ratio, this drill accommodates two indexable inserts compatible with the HPMT074006-GP insert style. The straight cylindrical shank measures 1-1/4 inches in diameter, and the tool includes through-coolant capability via a 1/4-inch shank-end coolant hole thread. Overall body length is 7.014 inches. Metalworking machinists and toolroom technicians install this drill on CNC machining centers and lathes with live tooling.

This indexable insert drill is suited for production drilling in ferrous and non-ferrous materials where consistent bore diameter and depth control are required. The right-hand cutting direction and straight-cylindrical shank make it compatible with standard ER and hydraulic toolholders in both vertical and horizontal machining center setups. The 3xD depth ratio is typical for through-hole and blind-hole operations in general machining, die, and mold work where a full solid-carbide drill would be cost-prohibitive at this diameter range.

Compatibility

Designed to accept HPMT074006-GP indexable inserts. Compatible drill style is HID. Verify toolholder bore and retention method against the 1.2500-inch decimal shank diameter and 3.000-inch shank length before installation.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the machine in a fully stopped and locked-out state per OSHA lockout/tagout procedures. Confirm toolholder bore diameter and coolant port alignment before mounting. Torque retention screws to the toolholder manufacturer specifications - do not use values not provided with the toolholder. Insert seating and clamping should be inspected before each use to prevent insert ejection during cutting.
