SPMT 090308 NS9530 indexable insert for drilling — Tungaloy (square, 90°, corner radius 0.8 mm)

The SPMT090308 is an indexable insert for drilling systems, designed as a finishing-grade, uncoated cermet insert for precision machining of steel components with low cutting forces and excellent surface finish.

• Finishing cermet grade NS9530
• Sharp cutting edge, low cutting forces
• Square insert with cylindrical hole & countersink
• Designed for indexable drilling systems

High-quality finishing performance with reduced cutting forces

The uncoated NS9530 cermet composition delivers a consistently sharp cutting edge that reduces cutting forces and improves surface integrity when machining steel. With a small corner radius (0.8 mm) and a geometry optimised for light depths of cut, this grade is intended primarily for finishing passes and continuous cutting operations. The result is less deflection in fragile drill assemblies and a more predictable workpiece finish, which supports reduced rework and more efficient downstream processes. Using a finishing-grade insert like this one can lead to shorter cycle times where high surface quality is a priority.

Built for secure clamping and system compatibility

As a square indexable insert with a cylindrical hole and single-sided countersink (40°–60°), the insert integrates into common drilling bodies and clamping systems with standardised pockets. The included angle of 90° and relief angle 11° are engineered to match typical drill geometries; the 3.18 mm plate thickness ensures robust seating while allowing reliable indexing. When pairing this insert with a compatible drill body, it is essential to match the insert size and pocket geometry to the drill diameter to guarantee correct seat and clamp engagement. The standardised form supports fast replacements and predictable setup times.

Consistent machining behaviour for industrial production

The indexable design and the single-sided chipbreaker deliver steady chip control during finishing operations, especially on continuous feeds. This contributes to reliable process outcomes, stable edge retention and longer usable life per index compared with unstable cutting conditions. The insert’s specification supports efficient tool handling in production environments where repeatability and process security are central concerns. Backed by Tungaloy’s tooling expertise, the grade aims to combine surface quality with operational economy for users focusing on consistent part quality.

FAQ

Which materials is this insert best suited for?
The NS9530 finishing grade is formulated for machining steel; the SPMT090308 insert from Tungaloy is optimised for steel finishing operations and continuous cuts.

Is the insert coated?
The SPMT090308 NS9530 is an uncoated cermet insert, chosen for its sharp edge and ability to produce high-quality surfaces without a coating layer.

How should the insert be mounted in a drill body?
Mount the square insert in a compatible indexable drilling body that accepts the 09 size and the central cylindrical hole with countersink; ensure the pocket geometry and clamp screw match the insert to achieve secure seating.

Can this insert be used for roughing or interrupted cuts?
This grade is a finishing sort geared towards continuous cuts and small depths of cut; it is not primarily intended for heavy roughing or highly interrupted cutting conditions.

What are the key geometric values to check when replacing inserts?
Verify the corner radius (0.8 mm), included angle (90°), relief angle (11°) and plate thickness (3.18 mm), and ensure the drill body pocket aligns with the insert’s cylindrical hole and countersink.
