SPMT090308 T9225 – Indexable insert for drilling systems (Tungaloy)

The SPMT090308 T9225 is an indexable cutting insert designed for drilling systems, engineered for medium to heavy steel machining where toughness and interrupted‑cut resistance are required.

• CVD-coated carbide T9225
• Robust universal grade for steels
• Square 09 form with 90° angle
• Cylindrical hole with countersink

Dependable cutting performance through material and coating

The combination of CVD‑coating and a carbide substrate in grade T9225 provides a balanced mix of hardness and toughness, which is especially beneficial for medium to heavy steel machining. This material composition reduces flank wear while maintaining edge strength under varying engagement conditions, meaning fewer unscheduled tool changes and more predictable process stability. The result is a tool blank that tolerates slight interruptions in the cut without premature chipping, improving overall productivity in serial drilling operations.

Geometry designed for secure clamping and repeatability

The insert’s square form (09) and 90° included angle deliver secure seating in standard drill bodies, while the 0.8 mm corner radius supports both chip formation control and edge robustness. The 3.18 mm plate thickness and the cylindrical hole with one‑sided countersink (40°–60°) ensure reliable clamping with common clamping screws. When matched correctly to the drill diameter and insert seat, this geometry provides consistent tool projection and repeatable hole quality across batches.

System integration and handling benefits

This grade is intended for use in a complete drilling system consisting of a drill body, matching insert, clamping screw and key. The insert’s single‑sided chipbreaker and square layout simplify inventory management, as the same insert type can be rotated for multiple cutting edges. For practical workshop integration, confirm seat geometry and drill diameter to select the correct insert size and orientation; correct matching minimises run‑out and improves surface finish, reducing rework and machining time.

Typical applications and machining advice

Engineered for general purpose drilling with indexable insert tools, this insert performs well on internal and external cutting edges during through‑hole and blind‑hole operations in steel and related alloys. The universal character of T9225 makes it suitable where varying cut conditions or intermittent engagement occur. For best results, pair the insert with a suitable drill body designed for square 09 inserts and use moderate feed rates when encountering interrupted cuts to exploit the grade’s toughness.

FAQ

Which materials is this insert suited for?
The SPMT090308 T9225 insert is recommended primarily for medium to heavy steel machining, benefiting from the CVD‑coated carbide grade for robust performance.

What are the key geometric specifications of the insert?
The insert conforms to ISO 090308 with a square 09 form, 90° included angle, 0.8 mm corner radius and a plate thickness of 3.18 mm.

How is the insert secured in a drilling system?
The insert is mounted in a compatible drill body using a clamping screw; the cylindrical hole with one‑sided countersink ensures secure seating and accurate repeatability when the drill body matches the insert seat.

Is the T9225 grade coated, and what advantage does that give?
Yes — T9225 is a CVD‑coated carbide grade; the coating increases surface hardness and wear resistance while the carbide core provides toughness for interrupted cuts.

Can this insert cope with interrupted cuts or variable engagement conditions?
The insert’s robust universal grade and edge geometry are developed to tolerate lightly interrupted cuts and changing engagement, making it suitable for demanding drilling tasks.
