SPMT090308 T9215 – indexable insert for drilling by Tungaloy

The SPMT090308 T9215 is an indexable insert designed for drilling systems, optimised for medium steel machining with a robust CVD-coated carbide grade.

• SPMT090308 T9215 CVD-coated carbide
• Designed for medium steel machining
• Square insert with 0.8 mm corner radius
• Cylindrical hole with 40°–60° countersink

High-performance coating and cutting material for longer tool life

The combination of CVD-coated carbide and a cutting-grade tuned for medium steel results in improved wear resistance and fracture toughness, enabling longer tool life under continuous or lightly interrupted cuts. CVD (chemical vapour deposition) forms a hard, adherent layer on the substrate that reduces flank and crater wear; this converts directly into fewer indexings and lower tooling costs over a production run. This behaviour is particularly valuable when reproducible results and stable process windows are required in series drilling operations.

Geometry tuned for reliable chip control and hole quality

With a 0.8 mm corner radius and 11° relief angle, the insert geometry balances edge strength and entry behaviour to reduce burr formation and improve hole integrity. The single-sided chipbreaker promotes predictable chip formation in medium-steel grades, reducing the risk of clogging in through-drilling and improving coolant access at the cutting zone. The square 09-format and 3.18 mm thickness provide a compact, stiff cutting edge, while the included-angle of 90° suits common drilling geometries in standardised drill bodies.

Mounting features and system compatibility explained

The insert is supplied with a cylindrical hole and a single-side countersink (40°–60°) to match the locating and clamping arrangements of compatible drilling bodies. When fitting the insert into a drill body, ensure the seat and clamping screw match the SPMT090308 geometry and that the drill diameter is compatible with the plate size and cutting-edge projection. Correct seating prevents micro-movements that can accelerate flank wear or cause unstable cutting conditions, so alignment and torque according to the drill system specification are recommended.

Practical benefits for workshop productivity

Adopting this grade reduces unplanned downtime thanks to consistent wear behaviour and an optimised chipbreaker that supports stable metal removal rates. The insert’s design is aimed at productivity: fewer tool changes, more reproducible hole dimensions, and predictable edge life. For operations seeking improved throughput with controlled operating costs, the balance of durability and chip control offers a concrete efficiency advantage.

FAQ

Which materials is this insert best suited for? The SPMT090308 T9215 insert is formulated for medium steel machining; the CVD-coated carbide grade combines wear resistance and toughness for continuous to lightly interrupted drilling.

How does the 0.8 mm corner radius affect hole quality? A 0.8 mm corner radius increases edge strength and reduces chipping at the drill entry, supporting more consistent hole diameters and improved surface finish in typical drilling cycles.

Is the SPMT090308 compatible with all drill bodies? Compatibility depends on the drill body’s seat and clamping design; the insert’s cylindrical hole and countersink (40°–60°) require a matching seat and screw arrangement used in standard drilling systems.

What advantage does the single-sided chipbreaker offer? The one-sided chipbreaker promotes controlled chip formation and evacuation in medium steels, which helps maintain a stable cutting process and reduces the risk of chip-related interruptions.

How should cutting data be adjusted for this insert? Cutting data should be selected in line with the drill body manufacturer’s recommendations and the material grade; the T9215 grade supports relatively high feed and speed in medium steels while maintaining edge life.
