TPMX170408R-B 170408 AH8015 indexable insert for drilling (Tungaloy)

TPMX170408R-B is a triangular indexable insert designed for use in drill systems, optimised for machining heat-resistant alloys and general drilling applications.

• PVD-coated carbide for heat resistance and wear control
• Triangular plate form for stable seating and indexing
• R0.8 corner radius for robust edge strength
• Special hole and chipbreaker B for improved chip control

Consistent performance in heat-resistant alloys

The insert combines a PVD-coated carbide substrate with the AH8015 grade to balance wear resistance and edge stability. This configuration reduces flank wear at elevated temperatures and maintains cutting capability over longer intervals, which translates into fewer tool changes and higher process uptime. The material choice is particularly suited to alloys that generate heat and abrasive conditions, delivering steady performance where uncoated grades often fail. Emphasis on measurable endurance keeps cycle times predictable and supports efficient planning in production environments.

Geometry and system compatibility for reliable drilling

The triangular plate form with a R0.8 corner radius and a 60° included angle provides a secure fit in compatible drill bodies and a repeatable cutting geometry when indexing inserts. The 11° relief angle helps to reduce rubbing at the flank and supports clean chip evacuation when combined with the specified chipbreaker B. Note that insert dimensions and seating must be matched to the drill diameter and the plate pocket; the overall system comprises the drill body, matching insert, clamping screw and setting key to ensure correct alignment and clamping force for safe, repeatable operation.

Application guidance and productivity benefits

Classified as a first-choice grade for machining hot, heat-resistant alloys, AH8015 offers an application-oriented compromise between long tool life and stable cutting edges. The PVD layer improves thermal resistance and reduces adhesion of workpiece material, which assists in maintaining surface finish and hole tolerance. When used in a properly configured drill system, these inserts contribute to improved productivity by reducing secondary operations and downtime. For best results, verify the insert seat and geometry against the drill diameter and consider cutting data adjustments for work-hardening or highly alloyed materials.

FAQ

What materials is this insert suitable for?
The AH8015 PVD-coated carbide grade is intended as a first choice for machining heat-resistant alloys and similar high-temperature materials; the insert performs well where thermal resistance and edge stability are required.

How should the insert be matched to a drill body?
The triangular insert must be matched to the drill diameter and pocket geometry; ensure the seat, clamping screw and key are correct so the TPMX170408R-B seats securely and delivers the intended cutting geometry.

What does the chipbreaker designation B indicate?
Chipbreaker B is designed to assist controlled chip formation and evacuation in drilling operations, helping to reduce clogging and improve surface quality when paired with the correct cutting parameters.

Can AH8015 inserts be used for finishing operations?
Yes — the balanced wear resistance and edge stability of AH8015 support consistent surface finishes in drilling, particularly when cutting parameters are set to suit the workpiece material and machine rigidity.

Which SKU should be referenced when ordering?
Order using SKU 4854282-Tungaloy or manufacturer SKU TUN4854282 to ensure the correct TPMX170408R-B insert and grade are supplied.
