SPMT 090308 AT9530 indexable insert for drilling — Tungaloy

SPMT090308 AT9530 is a square indexable insert intended for drilling applications, optimised for finishing and light machining of steel where surface quality and uniform wear are priorities.

• AT9530 coated cermet grade for fine finishing
• Square 09 form with 0.8 mm corner radius
• Cylindrical hole with one-sided countersink
• Designed for indexable drilling systems, 11° relief

Enhanced surface quality and consistent wear for finishing operations

The AT9530 coating on a cermet substrate delivers a balance between hardness and toughness that is tailored for finishing and light machining of steel. This combination reduces built-up edge formation and promotes uniform wear, which directly benefits workpiece appearance and dimensional consistency. As a consequence, cycle-to-cycle variability is reduced and downstream processes such as grinding or assembly experience fewer rejections. The cutting geometry emphasises controlled chip formation to protect the cutting edge while maintaining a fine surface texture.

Precise form and hole design for repeatable clamping and positioning

With a square 09 form and a corner radius of 0.8 mm, the insert provides defined contact points for repeatable seating in the drill body. The cylindrical hole with a one-sided countersink (40°–60°) secures the insert reliably with the matching clamp system, while the 11° relief minimises rubbing and friction during entry and exit. These mechanical attributes support stable toolholding and enable predictable performance across multiple tool changes, reducing downtime and ensuring consistent hole geometry in serial production.

System compatibility and straightforward integration into drilling workflows

The insert is supplied for use in conventional indexable drilling systems and forms part of a system comprising the drill body, matching insert, clamp screw and key. A plate thickness of 3.18 mm and the single-sided chipbreaker make the component suitable for operations focused on surface finish rather than heavy material removal. The design facilitates fast replacement and alignment, which shortens tool-change times and supports higher overall equipment effectiveness. Operators benefit from clearer process parameters and easier integration into existing tool libraries.

FAQ

What materials is this insert suitable for? The SPMT090308 AT9530 insert is intended primarily for finishing and light machining of steel; the AT9530 coated cermet grade improves surface finish and wear uniformity when machining common steel grades.

How does the hole and countersink affect mounting? The cylindrical hole with a one-sided countersink ensures secure seating in compatible drill bodies; the feature allows positive clamping and correct axial positioning of the insert during drilling operations.

Is the insert intended for heavy roughing applications? No. The geometry and the AT9530 grade are optimised for finishing and light machining. For heavy roughing, a more robust grade and a different chipbreaker geometry would be recommended.

What benefits does the 0.8 mm corner radius provide? A 0.8 mm corner radius balances edge strength with the capability to produce a fine surface finish; it reduces the likelihood of edge chipping while maintaining good dimensional definition in drilled holes.

Which accessories are required to fit the insert into a drilling system? Installation requires the appropriate drill body, the matching insert seat, a clamp screw and the corresponding key as specified by the drilling-system manufacturer; these elements form the complete assembly for safe and repeatable operation.
