SPMN120312 T5115 SPMN turning indexable insert (Tungaloy) — CVD-coated carbide, 1.2 mm nose radius

SPMN120312 T5115 is an ISO-form square turning insert designed for general turning tasks, optimised for cast-iron applications and compatible with standard SPMN holders.

• CVD-coated universal grade T5115
• Optimised for cast iron machining
• ISO SPMN120312 square insert
• 11° relief angle, 3.18 mm thickness

Consistent tool life and material suitability for cast iron

The combination of a CVD coating with a robust carbide substrate in the T5115 grade delivers a well-balanced mix of wear resistance and edge stability, specifically tuned for cast-iron turning. This balance reduces unexpected tool wear and maintains cutting-edge integrity across medium-duty turning cycles, which translates into fewer indexings and lower tooling costs per component. The insert’s geometry and coating result in predictable cutting behaviour, enabling steady cycle times and reliable surface finish when used with adequately rigid set-ups.

Precise fit and fast changeover in ISO indexable systems

Designed to the ISO SPMN form, the insert’s square shape and dimensional accuracy ensure repeatable seating and secure clamping in matching external holders or boring bars. Important dimensional data such as the 1.2 mm nose radius, 3.18 mm thickness and 11° relief angle are decisive for selecting the correct holder and clamping kit; correct pairing reduces set-up time and minimises runout. Thanks to the standardised form and tolerance classes, the component can be integrated easily into existing indexable systems, supporting fast replacement and consistent part quality on production lines.

Practical application notes and operational advantages

This insert is intended primarily for external and internal turning where cast iron is the predominant material, and where a universal grade is preferred to cover a range of cutting conditions. The absence of an integral chipbreaker means the cutting-edge performance depends on matching the grade and geometry to the process stability and workpiece condition; consider the machining strategy (feed, depth of cut, rigidity) to make the most of the T5115 characteristics. The square configuration offers four effective cutting corners, and the CVD coating helps control built-up edge and improves thermal resistance during interrupted cuts, supporting productivity and surface quality without sacrificing tool life.

FAQ

What materials is this insert suited for? The SPMN120312 T5115 insert is formulated for cast-iron machining; the T5115 grade and CVD coating combine to offer balanced wear resistance and edge stability for grey and nodular cast irons.

How does the insert’s geometry affect application choice? The square SPMN form with a 1.2 mm nose radius provides a compromise between finishing and light roughing; the 11° relief and 3.18 mm thickness support rigidity and consistent seating in ISO SPMN holders.

Is a chipbreaker included with this design? This insert is supplied without an integral chipbreaker; chip control must be achieved via process parameters, holder geometry or a separate chip control solution to match the chosen machining conditions.

Which holders are compatible with the ISO SPMN120312 form? Compatibility depends on form, relief, tolerance class, clamping method, size and thickness; select an external holder or boring bar designed for ISO SPMN inserts and verify clamping hardware and backup shim fit.

What is the manufacturer article number and SKU for ordering? The manufacturer’s article number is 6862107 and the SKU is 6862107-Tungaloy; specify the ISO designation SPMN120312 and grade T5115 when enquiring to ensure correct supply.
