SPMT 090308 T9225 indexable insert for drilling systems — Tungaloy

The SPMT 090308 T9225 is a square indexable insert for drilling applications, engineered for medium to heavy steel machining with a robust CVD-coated carbide body and a single-sided chipbreaker.

• CVD-coated carbide, grade T9225
• Designed for medium to heavy steel machining
• Square insert size 09, 0.8 mm corner radius

Consistent cutting performance for medium to heavy steel

The CVD-coated carbide grade T9225 is formulated to combine toughness with thermal resistance, which supports stable cutting under variable engagement conditions. This results in reduced flank wear and reliable tool life when machining steels that impose fluctuating loads or slight interruptions. The single-sided chipbreaker assists in forming manageable chips and helps maintain surface quality, while the insert’s robust substrate preserves edge integrity in longer production runs.

Secure geometry and clamping for repeatable accuracy

The square plate geometry with a nominal 90° cutting angle and a 0.8 mm corner radius provides a balance between strength and profile definition for hole entries and finishes. With a plate thickness of 3.18 mm, the insert offers sufficient support in the pocket; the cylindrical hole with single-side countersink (40°–60°) ensures centration and secure clamping in compatible drilling bodies. The 11° relief angle contributes to controlled tool engagement and reduced rubbing, promoting consistent hole size and surface finish across batches.

Practical system guidance to maximise productivity

These inserts are supplied as part of a modular drilling system comprising the drill body, matching insert, clamp screw and key; correct pairing of insert size and geometry with the drill diameter and seat is essential for optimum results. Selection of the SPMT 090308 T9225 for applications with intermittent cuts or variable chip loads will typically yield longer in-service intervals and fewer unscheduled tool changes. For production-oriented shops, this translates into improved machine uptime and cost-effective material removal per insert while preserving component quality.

FAQ

What materials is this insert best suited for?
The SPMT 090308 T9225 insert is designed primarily for medium to heavy steel machining; the CVD-coated carbide grade T9225 provides toughness for variable cutting conditions.

How does the 0.8 mm corner radius affect hole quality?
A 0.8 mm corner radius offers increased edge strength for entry and exit zones, reducing the risk of chipping while maintaining acceptable hole geometry for many standard drilling operations.

What type of hole mounting does the insert require?
The insert features a cylindrical hole with a single-side countersink (40°–60°) and must be used in a compatible drill body with the correct seat and clamp screw to ensure secure clamping and repeatable positioning.

Can these inserts handle interrupted cuts?
Yes, the T9225 grade is formulated for applications where slight interruptions or changing engagement occur, offering increased toughness compared with more brittle grades.

Is the insert reversible or indexable for multiple edges?
As a square indexable insert, the insert provides multiple cutting edges per insert; correct indexing in the drilling system enables economical use of all edges.
