Kennametal 1805013 Indexable Drill Insert Dfthp KC7140

Product Description

The KENNAMETAL 1805013 is a solid carbide indexable drill insert designed for use in indexable drilling toolholders operating in demanding metal-cutting applications. It carries the DFTHP designation, combining the DFT insert style with an HP chipbreaker geometry engineered to manage chip flow in deep-hole and through-hole drilling operations. The insert is coated via PVD process with TiN and TiCN layers under the KC7140 manufacturer grade, which targets C5 and C6 material grades. Key dimensions include a 15 mm (0.5906 inches) inscribed circle, a thickness of 0.2067 inches, and a 0.80 mm (0.0315 inches) corner radius. The trigon shape with an 84-degree included angle and an 8-degree relief angle suits production drilling environments where insert indexability and edge consistency matter.

This insert is suited for production machining shops, job shops, and aerospace or general manufacturing environments running indexable drill bodies that accept DFT-style trigon inserts. The HP chipbreaker geometry performs well in steel and alloy steels where chip control is a priority. It is installed by machinists and tooling technicians maintaining or setting up CNC machining centers and drill presses. The insert size designation is 090508, and it is sold individually per package with a minimum order quantity of 5 units.

Key Features

• Solid carbide substrate with PVD-applied TiN and TiCN multilayer coating under KC7140 grade
• HP chipbreaker geometry designed for controlled chip evacuation in drilling operations
• 84-degree trigon (Trigon) shape with 8-degree relief angle for positive cutting action
• 15 mm inscribed circle (0.5906 inches) with 0.80 mm corner radius for defined edge geometry
• Insert size 090508 with 5.5 mm mounting hole diameter (0.2165 inches) for secure clamping in compatible drill bodies
• Lightweight at 0.022 pounds - practical for high-volume tooling changeouts

Compatibility

Designed as a direct-fit replacement for DFTHP-style trigon indexable drill inserts with insert size designation 090508 in toolholders accepting a 5.5 mm mounting hole and 15 mm inscribed circle geometry. Verify toolholder manufacturer specifications before installation.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician with the machine spindle fully stopped and the machine locked out per established lockout/tagout procedures. Use the correct torque wrench and manufacturer-specified clamping screw to secure the insert in the drill body seat - do not overtighten by hand. Inspect the insert pocket and clamping screw for wear or damage before seating a new insert. Confirm insert orientation matches the toolholder geometry before resuming cutting operations.
