XPMT 110412 AH7020 indexable insert for drilling – Tungaloy

A precise indexable cutting insert, XPMT 110412 AH7020, designed for general drilling applications in modular TDX drill bodies

• PVD-coated carbide grade AH7020
• Chipping- and wear-resistant cutting edge
• 1.2 mm corner radius for stable engagement
• Cylindrical hole with single‑side countersink

Consistent cutting performance through PVD-coated carbide

The PVD-coated carbide grade AH7020 delivers a balanced combination of wear resistance and edge integrity for general drilling operations. The coating improves thermal and abrasive resistance while the carbide substrate maintains toughness, which together reduce premature flank wear and edge chipping. This results in more consistent hole quality and extended tool life under fluctuating cutting conditions, supporting higher process reliability in production runs.

Predictable chip formation and secure clamping for reduced downtime

A deliberately engineered 1.2 mm corner radius and the chipbreaker DW geometry promote controlled chip formation and stable cutting engagement. The insert’s cylindrical hole with single‑side countersink (40°–60°) ensures secure clamping in TDX-style holders and helps maintain repeatable tool positioning. These design aspects reduce the risk of insert loosening and unexpected interruptions, contributing to smoother cycle times and fewer tool changes on the shop floor.

Modular system design for flexible tooling strategies

The insert is part of the TungDrillTwisted family, which comprises TDX/C‑TDX drill bodies, XPMT inserts, clamping screws and a single key. Families are differentiated by overhang (L/D) and interface, enabling the selection of diameter, L/D ratio, shaft and insert type that best match machine capability, workpiece material and coolant strategy. This modular approach reduces inventory variety while enabling rapid reconfiguration for diverse drilling tasks.

Practical advantages for machining operations

Designed for general drilling, the special plate form and robust PVD-coated hardmetal substrate favour applications that demand a sharp cutting edge combined with process security. The insert’s features support repeatable hole tolerances and surface condition, while the compatible system components simplify assembly and replacement. When process parameters or workpiece composition change, the modular nature of the system allows straightforward adaptation without a complete tooling redesign.

FAQ

What materials is this insert best suited for? The XPMT 110412 AH7020 insert is formulated as a wear- and chipping-resistant PVD-coated carbide, making it suitable for a broad range of general drilling tasks where a sharp cutting edge and process security are required.

How does the 1.2 mm corner radius affect drilling results? A 1.2 mm corner radius increases engagement stability and helps distribute cutting forces, which promotes improved hole quality and reduces the likelihood of edge chipping with the XPMT insert in TDX bodies.

Which drill bodies are compatible with these inserts? The insert is intended for use with the TungDrillTwisted family’s TDX and C‑TDX drill bodies; compatibility depends on the specific overhang (L/D) and interface variation selected for the application.

What is the benefit of the cylindrical hole with single‑side countersink? The cylindrical hole combined with a single‑side countersink (40°–60°) provides secure clamping and precise seating in the holder, supporting repeatable positioning and reduced insert movement during drilling.

Can the insert geometry reduce tool changes and downtime? Yes. The combination of PVD coating, robust carbide substrate and chipbreaker geometry delivers stable cutting behaviour and prolonged edge life, which helps reduce frequent insert replacements and associated downtime.
