Sumitomo RCMT120400 AC8115P – Turning Carbide Insert

The Sumitomo RCMT120400 turning carbide insert, grade AC8115P, excels in high-speed machining of steel workpieces, leveraging its tin coating to minimize friction and heat buildup, and its round shape to facilitate smooth material removal. With a 12mm inscribed circle and neutral geometry, this insert is well-suited for a variety of turning operations, from roughing to finishing, on steel alloys. Its Absotech finish enhances edge sharpness and reduces built-up edge formation, making it an ideal choice for high-volume machining applications where tool life and surface finish are critical.

Buying Considerations

Single-pack option — useful for prototype runs or qualification before bulk commitment. Entry-tier pricing makes this a low-risk option for trialing Sumitomo tooling on a new material.

Reminder: Holder rigidity, lead angle, and approach all influence how this insert wears. Pair with a holder rated for the same cutting forces.
