SCMT120408 T515 square indexable insert for milling — Tungaloy

The SCMT120408 T515 is a square indexable insert engineered for milling applications, optimised for economical and stable machining of cast iron with Tungaloy’s CVD-coated carbide grade.

• CVD-coated carbide grade T515
• Square insert SCMT 12×12 with 0.8 mm radius
• 90° cutting edge for general milling
• Cylindrical hole with single-side countersink

Secure, economical cast-iron machining with CVD-coated carbide

The CVD-coated carbide grade T515 provides a balance of wear resistance and cost-effectiveness for the machining of cast iron, promoting stable chip formation and extended tool life. Chemical vapour deposition (CVD) produces a thin, hard coating that protects the substrate during elevated temperatures and interrupted cuts; this reduces flank wear and helps maintain surface quality over longer production runs. As a result, shops benefit from fewer index changes and more predictable cycle times, contributing to lower overall machining costs.

Predictable edge behaviour from square geometry and 0.8 mm radius

A square form with a 0.8 mm corner radius and a 90° included angle delivers predictable contact conditions at the cutting edge, making the insert suitable for face, shoulder and contour milling where both robustness and edge strength matter. The modest radius increases corner strength versus a sharp corner while still supporting acceptable surface finish, so operators can select cutting parameters that favour productivity without compromising part tolerances. The standard geometry simplifies toolholder selection and process planning in multi-tool setups.

Stable mounting and compatibility for secure production

The insert’s cylindrical hole with a single-side countersink (40°–60°) and a thickness of 4.76 mm ensure secure clamping in suitably matched cutter bodies; correct match of the insert seat, geometry and cutter body is essential for repeatable results. The central hole and countersink arrangement supports axial and radial clamping loads, reducing micro-movement under cutting forces and increasing process stability. Clear system compatibility avoids misfits: the insert must be used in Tungaloy milling systems that accept SCMT-style indexable inserts.

Process-focused chip control and flexible application range

An one-sided chipbreaker design directs chips reliably for the intended milling modes and supports operations such as face, shoulder, slot, high-feed and contour milling depending on the assigned cutter family. The insert’s combination of grade and chip control is selected for interrupted and continuous cuts in cast iron, helping to avoid built-up edge and ensuring consistent surface quality. For manufacturers seeking reproducible productivity with economical tooling, this indexable insert integrates into standard milling tool systems and tooling strategies.

FAQ

What materials is this insert designed for?
The SCMT120408 T515 insert is formulated for machining cast iron; the T515 CVD-coated carbide grade delivers stable chip formation and good wear resistance for this material class.

Can this insert be used in interrupted cuts?
Yes, the T515 grade and the insert’s geometry are suitable for interrupted and continuous milling in cast iron, providing reliable edge strength and reduced sensitivity to breakage.

What does the 0.8 mm corner radius mean for surface finish?
A 0.8 mm corner radius increases corner strength and tends to produce a slightly more robust cutting edge than a sharp corner, maintaining acceptable surface finish while extending edge life.

Is the insert compatible with all milling bodies?
The insert requires a matching cutter body and seat designed for SCMT inserts; the cylindrical hole with countersink and the specified geometry must be technically compatible with the milling system used.

How does the one-sided chipbreaker affect chip control?
The one-sided chipbreaker is designed to direct chips for typical milling operations indicated and helps maintain consistent chip flow, which supports surface quality and tool life.
