SCMT09T304 T515 SCMT turning insert – CVD‑coated carbide, 0.4 mm radius — Tungaloy

The SCMT09T304 T515 is an ISO‑standard turning insert developed for economical external and internal turning of cast iron, offering robust cutting performance in interrupted cuts and continuous machining.

• CVD‑coated carbide grade T515
• Economic machining of cast iron
• Square form with 90° included angle
• 0.4 mm corner radius for edge strength

Increased productivity through CVD‑coated carbide

The CVD‑coated carbide grade T515 combines wear resistance with a balanced toughness suited to frequent chip formation when turning cast iron. The chemical vapour deposition process produces a thin, adherent layer that reduces flank wear and extends productive life under standard cutting speeds. For production environments where cycle times and tool change intervals matter, this T515 grade helps reduce overall machining costs by enabling longer runs between indexings and consistent surface finish.

Secure geometry for consistent component quality

A square insert with a 90° included angle and a 0.4 mm corner radius provides a robust edge for facing and turning shoulders, improving stability where rigidity is limited. The 7° clearance helps avoid rubbing on the flank while maintaining a controlled cutting contact. The plate thickness of 3.97 mm contributes to stiffness in the clamping system, which in turn stabilises vibration and supports repeatable dimensional accuracy on serial parts.

Designed for straightforward holder compatibility and chip control

Compatibility to a holder is defined by form, clearance angle, tolerance class, mounting, size and thickness; the square form and with‑hole design (cylindrical hole plus one‑sided countersink, 40°–60°) ensure simple, repeatable clamping on many standard external holders. The one‑sided chipbreaker is shaped to promote predictable chip formation when machining cast iron, which reduces the risk of entanglement and protects part surfaces. These features together lower set‑up time and reduce the likelihood of unplanned stops for chip clearing.

Practical selection guidance for workshop reliability

Choose the chipbreaker and grade based on workpiece stability and cut conditions: the T515 grade is recommended for economical roughing and medium finishing in cast iron, while the single‑sided chipbreaker suits interrupted cuts. When insert life and surface integrity are priorities, pairing the insert with a correctly sized, rigid holder and matching feed rates optimises performance. For specific applications and holder matching, technical advice is available to ensure the chosen insert meets the required balance of tool life and productivity.

FAQ

What materials is this insert best suited for?
The SCMT09T304 T515 insert is optimised for machining cast iron and performs well in interrupted and continuous turning where reliable chip formation is required.

How does the T515 grade affect tool life?
The T515 CVD‑coated grade provides enhanced wear resistance, which typically extends tool life compared with uncoated grades under comparable cutting conditions.

Which holders are compatible with this ISO insert?
Compatibility depends on the holder's form, clearance, tolerance class, mounting and thickness; the square SCMT09T304 form and its hole/countersink arrangement match many standard external holders designed for ISO inserts.

What is the purpose of the one‑sided chipbreaker?
The one‑sided chipbreaker on this insert promotes controlled chip formation during turning of cast iron, reducing chip length and improving surface protection.

How should the corner radius and clearance angle influence feed and speed choices?
A 0.4 mm corner radius gives edge strength for heavier cuts; combined with the 7° clearance angle, it supports moderate feeds and speeds that favour stability and surface finish rather than maximum material removal per pass.
