SPMT090308 T9225 indexable insert for drilling — Tungaloy

SPMT090308 T9225 is a square indexable insert designed for drilling systems, offering a robust CVD-coated carbide grade for demanding steel machining

• CVD-coated carbide grade T9225
• Square insert with 0.8 mm corner radius
• Single-sided chipbreaker for reliable chips
• With central hole and 40°–60° countersink

Consistent metal removal for efficient drilling

The insert provides predictable cutting behaviour thanks to the CVD-coated cemented carbide specification and the optimised chip control. The coating and grade T9225 balance wear resistance with fracture toughness, which means longer tool life under medium to heavy steel loads and when encountering slightly interrupted cuts. The square format with a 0.8 mm corner radius supports four usable edges and contributes to cost efficiency per edge, while the single-sided chipbreaker keeps chips consistent for stable evacuation in through-hole drilling.

Designed for demanding steel applications

For operations that require repeatable results, the insert’s composition and geometry ensure stable cutting and good surface quality. The 11° relief angle and the 90° seating geometry help maintain a secure cut engagement and reduce rubbing, resulting in lower heat and improved edge life. Where process reliability matters, the material pairing—cemented carbide with a CVD layer—offers a compromise between hardness and toughness to resist built-up edge formation and premature chipping during variable feeds or interrupted sections.

System compatibility and mounting guidance

The insert is made for use in indexable drilling systems and must be matched to the drill body and seat geometry. The recommended system assembly comprises a drill body, the matching insert, a clamping screw and the appropriate key; the central hole with a single-side countersink (40°–60°) supports secure clamping and correct seating. Confirm seat size and drill diameter when selecting the plate, as correct fitment is essential for angular accuracy and repeatable bore quality. The insert designation and series note the intended application as part of an indexable drilling system.

Practical benefits for workshop integration

Choosing this insert supports operational continuity: its multi-edge square form reduces changeover frequency, the robust grade tolerates varying engagement conditions and the chipbreaker design simplifies chip handling. For shops focused on productivity in the machining of medium to heavy steel, the insert offers a pragmatic balance of economy and performance, enabling longer, more predictable tool cycles and reduced downtime for edge changes.

FAQ

What materials is this insert suited for?
The insert is specified for medium to heavy steel machining; the CVD-coated T9225 grade is formulated for robust performance under variable engagement and slightly interrupted cuts.

How is the insert secured in the drill system?
The SPMT090308 insert is mounted in a drill body using a clamping screw; the central hole with a 40°–60° countersink ensures correct seating and secure fastening.

How many cutting edges are available per insert?
The square form provides multiple cutting edges; rotation of the insert after wear allows economical use of each edge before replacement.

Does the insert handle interrupted cuts?
Yes, the T9225 grade combines toughness with wear resistance to tolerate light interruptions and changing engagement conditions without rapid edge failure.

Which drill components should be checked for compatibility?
Verify the drill body seat, the insert seat geometry and the matching clamping screw; correct seating and torque ensure angular accuracy and repeatable bore quality.
