SPMT090308 GT9530 — Indexable insert for drilling (Tungaloy)

The SPMT090308 GT9530 is a square indexable insert for drilling systems, designed for finishing to light universal operations in steel.

• Coated cermet grade GT9530 for wear resistance
• Square insert, ISO 090308, 0.8 mm corner radius
• 11° clearance angle for reliable cutting engagement

Consistent finishing through a coated cermet grade

The SPMT090308 GT9530 insert uses a coated cermet formulation engineered for stable cutting in finishing to light universal applications. The grade emphasises wear resistance and surface quality, which translates into fewer edge changes and more consistent part finish under steady machining conditions. By prioritising abrasion resistance and edge stability, the insert helps maintain process repeatability and reduces unscheduled tool interventions, offering measurable productivity benefits in serial drilling tasks.

Geometry tailored for secure seating and chip control

Optimised geometry delivers predictable cutting behaviour and secure clamping. The combination of a 0.8 mm corner radius and one-sided chipbreaker improves entry and exit performance while reducing the risk of edge chipping in interrupted cuts. The 11° clearance angle lowers flank rubbing and heat build-up, and the 90° insert angle with a square plate form allows flexible indexing in dedicated drill bodies. The plate is supplied with a cylindrical hole and single-sided countersink (40°–60°) to ensure positive location and axial seating in compatible toolholders.

Easy system integration and economical operation

Integration into modular drilling systems is straightforward: the system comprises a drill body, matching indexable plate, clamp screw and key, enabling rapid replacements and consistent repeatability. The 3.18 mm plate thickness and standard ISO 090308 sizing simplify selection when matching seat geometry and drill diameter. Reliable performance under stable cutting conditions reduces overall tooling consumption and supports predictable cycle times.

FAQ

Which materials is this insert suitable for?
The SPMT090308 GT9530 is optimised for machining steel and is specified as a wear-resistant finishing to light universal grade, providing improved surface finish under stable cutting conditions.

How is the insert secured in the drilling system?
The plate locates via its cylindrical hole and single-sided countersink and is clamped in a dedicated drill body using a clamp screw and key as part of the modular system.

What effect does the corner radius have on component finish?
The 0.8 mm corner radius helps to produce a consistent surface finish while offering a degree of robustness at the cutting edge, reducing the likelihood of chipping in finishing operations.

Is the SPMT090308 compatible with standard ISO 090308 seats?
Yes; the insert follows the ISO 090308 specification, but seat geometry and drill diameter should be checked to ensure correct seating and clearance.

What additional components are required to fit the insert?
A matching drill body, clamp screw and the appropriate key are required; these components enable secure fixing and accurate repeatability for the insert.
