Hertel 4006155 Indexable Drill Insert HP130D Diamond

Product Description

The HERTEL 4006155 is a solid carbide indexable drill insert designed for high-performance drilling operations in machining environments. This insert features an 80-degree diamond shape with a neutral cutting direction and a GP chipbreaker geometry. The insert carries a TiAlN and AlCrN dual coating applied via PVD process, providing thermal resistance and wear protection during metal cutting. With an inscribed circle of 0.2953 inches (7.5 mm), a thickness of 0.1575 inches, and a corner radius of 0.0236 inches (0.60 mm), it is suited for precision indexable drill bodies used in CNC turning centers and machining cells. Machinists and tooling technicians select this insert for general-purpose drilling applications requiring consistent edge performance.

This insert is intended for use in indexable drill toolholders that accept the HPMT insert style. Typical applications include through-hole and blind-hole drilling on ferrous and non-ferrous workpieces in production machining environments. The GP chipbreaker geometry supports general-purpose chip control across a range of feeds and speeds. The PVD-applied TiAlN and AlCrN coating layers extend tool life in both dry and minimum-quantity lubrication setups. This insert is sold individually, with a minimum order quantity of 10 units.

Key Features

• Solid carbide substrate for rigidity and edge retention

• 80-degree diamond shape with neutral cutting direction
• GP chipbreaker for general-purpose chip management
• 0.60 mm corner radius (0.0236 inches) for controlled edge geometry
• Insert size 074006 compatible with HPMT-style indexable drill bodies

Compatibility

Designed for use in indexable drill toolholders accepting the HPMT insert style. Verify toolholder seat geometry and insert size 074006 specification before ordering.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician with the machine spindle fully stopped and locked out. Use the appropriate torx or hex key torque driver as specified by the toolholder manufacturer when seating the insert. Inspect the insert pocket and clamping screw for wear or damage before fitting a new insert. Never force an insert into a seat that shows signs of debris, deformation, or misalignment.
