SPMT 090308 T6215 indexable insert for drilling – Tungaloy

SPMT 090308 T6215 is an indexable insert intended for drilling systems, specified for use with replaceable-plate drill bodies and designed to handle rostfreier Stahl under predominantly stable cutting conditions.

• CVD-coated carbide, grade T6215
• Square insert, 90° cutting angle
• Cylindrical hole with single-side countersink (40°–60°)

Stable performance through CVD-coated carbide technology

The SPMT090308 T6215 insert is manufactured from cemented carbide with a CVD coating, offering a balance between wear resistance and edge strength that supports longer tool life in production runs. The coating reduces abrasive wear when machining rostfreier Stahl and stabilises the cutting edge under continuous operation. For machining engineers, this translates into fewer index changes and more predictable cycle times; for production managers, the insert’s consistent flank wear behaviour supports repeatable hole quality and helps to reduce scrap rates. The CVD process deposits hard ceramic layers that are well suited to the thermal and mechanical loads typical of drilling operations, making the grade particularly apt for stable to slightly interrupted cutting conditions.

Geometry and clamping deliver repeatable hole accuracy

Designed as a square insert with a nominal 90° cutting face, the plate features a corner radius of 0.8 mm and a clearance angle of 11°, combining to provide a controlled cutting edge for radial stability and surface finish. The 3.18 mm thickness and central cylindrical hole with one-sided countersink (40°–60°) enable secure clamping in standard drill bodies, preventing micro-movements that would otherwise affect concentricity. The incorporated one-sided chipbreaker manages chip flow in radial drilling, lowering the risk of chip re-cutting and improving evacuation from the hole. Together, these geometric elements support precise hole diameters and reduced vibration during drilling, which is particularly beneficial when producing series components with tight tolerances.

Practical application advice and system compatibility

This insert belongs to a model series intended for drilling with indexable-plate systems; the system comprises the drill body, the corresponding insert, a clamping screw and a key. Matching plate size and seat geometry to the drill diameter is essential: the ISO designation 090308 denotes the plate geometry and must be checked against the intended drill body and seat. The grade T6215 is formulated for rostfreier Stahl and performs best under stable cutting conditions or slight interruptions; in applications with severe interruption, a different grade or modified parameters may be preferable. The insert’s design facilitates straightforward replacement and indexing, minimising downtime while maintaining process stability in machining cells and workshop environments.

FAQ

What drill bodies are compatible with this insert? The SPMT090308 T6215 insert fits drill bodies designed for ISO 090308 square plates; compatibility requires matching the plate seat and clamping geometry of the drill body.

Is this grade suitable for stainless steel workpieces? Yes, the T6215 CVD-coated carbide grade is engineered for machining rostfreier Stahl under stable or slightly interrupted cutting conditions.

How does the 0.8 mm corner radius affect hole quality? The 0.8 mm corner radius helps to distribute cutting forces and improve surface finish while reducing edge chipping, supporting consistent hole dimensions in serial production.

What does the cylindrical hole with countersink mean for assembly? The central cylindrical hole plus the one-sided countersink (40°–60°) provides a secure mechanical seating and repeatable clamping position in compatible drill bodies.

Can the insert handle interrupted cuts? The insert is optimised for stable to slightly interrupted conditions; heavy interruption may require an alternative grade or adjusted cutting parameters.
