XPMT 110412 AH7020 XPMT110412R-DS — Indexable insert for drilling with PVD-coated carbide and cylindrical hole + countersink by Tungaloy

The XPMT110412R-DS AH7020 is an indexable insert designed for the TungDrillTwisted full-drill system, engineered for general drilling tasks where a sharp cutting edge and dependable process security are required.

• PVD-coated carbide AH7020
• Compatible with TungDrillTwisted TDX drill bodies
• Cylindrical hole with 40°–60° one-sided countersink
• 1.2 mm corner radius and 11° clearance angle

Consistent tool life through a wear-resistant grade

The core advantage of the insert is the AH7020 grade, a PVD-coated cemented carbide developed for high resistance to wear and edge chipping. This material combination delivers predictable performance during extended cycles, reducing the frequency of insert changes and machine downtime. By stabilising the cutting edge, the insert supports improved process security and allows for more consistent cycle times in serial drilling operations.

Secure clamping and system compatibility for reliable set-up

The insert’s cylindrical hole with a one-sided countersink (40°–60°) and the matching shank/interface concept ensure robust mounting in TDX drill bodies of the TungDrillTwisted family. The system comprises TDX/C-TDX drill bodies, XPMT inserts, clamping screws and the matching key, which together simplify configuration by length/overhang (L/D) and interface. This results in a dependable connection that resists movement under cutting loads and supports repeatable concentricity.

Improved chip control and stable cutting geometry

Equipped with the DS chipbreaker and a 1.2 mm corner radius, the insert is optimised for controlled swarf formation and stable cutting forces. The modest corner radius offers a balance between edge strength and surface finish, while the 11° clearance angle reduces rubbing on the flank face. Together these features help to maintain surface quality and reduce the risk of built-up edge on materials that tend to work harden.

Practical flexibility for general drilling applications

The indexable design permits quick replacement and selection of insert geometry to match machine capability, coolant strategy and workpiece requirements. When combined with the TungDrillTwisted drill bodies, the system supports a wide range of drilling tasks within general production environments. Specification of diameter, L/D ratio and shank should be matched to the application to exploit the PVD-coated AH7020 grade and the insert’s mechanical features for optimum results.
