SPMT090308 AH120 – indexable insert for drilling (Tungaloy)

A SPMT090308 AH120 indexable insert for drilling systems, designed to deliver wear resistance and chip control in production drilling applications.

• PVD-coated carbide grade AH120 for wear resistance
• 90° square insert with 0.8 mm corner radius
• Cylindrical hole with one-sided 40°–60° countersink
• Suitable for indexable drilling systems, 3.18 mm thick

Improved process reliability through a coated carbide grade

The PVD-coated substrate and the carbide composition of this insert provide a combination of hardness and edge stability that is well suited to demanding drilling tasks. The AH120 grade was selected for its wear resistance and reduced tendency to chip, which supports longer tool life and more consistent cycle times. Used in series production, the insert reduces the frequency of index changes and contributes to steady component quality, while the sharp cutting edge maintains hole geometry over longer operating periods.

Geometry and clamping details that simplify integration

The square 90° geometry with a 0.8 mm corner radius and a 11° clearance angle is optimised for standard insert-style drilling systems and must be matched to the drill body and insert seat. The insert is supplied with a cylindrical hole and a one-sided countersink (40°–60°) to ensure secure clamping and repeatable seating. With a plate thickness of 3.18 mm and a size designation of 09 in a square form, this indexable plate is designed for reliable fixation using the system’s clamping screw and key; the system architecture comprises the drill body, matching insert, clamping screw and tightening tool.

Coating, chip control and typical applications

The PVD coating enhances surface hardness and thermal resistance, improving edge retention under cyclic loads and aiding in the evacuation of chips when combined with the single-sided chipbreaker. The result is a balance between cutting performance and robustness that suits drilling operations where a sharp cutting edge and process security are essential. Typical use cases include production drilling with indexable inserts where hole quality, repeatability and reduced tool intervention are required; the insert’s design supports stable chip formation and predictable wear progression.

FAQ

What drilling applications is this insert designed for? The SPMT090308 AH120 Tungaloy insert is intended for indexable drilling systems used in production environments where a sharp cutting edge and process security are required; it is particularly effective where wear resistance and chip control are priorities.

How should the insert be mounted in a drilling body? The insert is mounted in the drill body using the system’s clamping screw and key; the SPMT090308’s cylindrical hole with a one-sided countersink (40°–60°) ensures repeatable seating and secure fixation.

What benefits does the AH120 grade offer compared with uncoated grades? The AH120 PVD-coated carbide grade provides improved edge stability and wear resistance, reducing the frequency of index changes and supporting consistent hole quality in serial drilling tasks.

Can the insert’s geometry be used for different drill diameters? Insert size and geometry must be matched to the drill diameter and the insert seat; the SPMT090308 form is compatible with systems designed for square, size 09 plates and should be verified against the drill body specification.
