CNMA 090404 T515 — ISO turning insert for cast iron, Tungaloy

The CNMA 090404 T515 is an ISO rhombic turning insert designed for efficient external and internal turning of cast iron components.

• ISO rhombic insert CNMA 090404
• CVD‑coated carbide grade T515
• Suited for cast iron machining
• 0.4 mm corner radius, 80° cutting angle

Productivity gains with a CVD‑coated grade built for cast iron

The CVD‑coated carbide grade T515 combines a wear‑resistant coating with a substrate engineered for stable cutting under interrupted and continuous cuts in cast iron. This configuration increases usable tool life and reduces the frequency of insert changes, translating into measurable cycle‑time savings on repetitive turning operations. The insert’s coating improves edge strength at elevated temperatures, allowing moderately higher cutting speeds while maintaining dimensional consistency and surface quality. The result is improved process economy and predictable performance in series production.

Interchangeability and secure clamping for fast changeovers

Designed to ISO dimensions, the rhombic insert ensures straightforward replacement across compatible holders. The geometry with an 80° main cutting angle and a 0° relief gives robust engagement for heavy cuts, while the 0.4 mm corner radius balances strength and edge roundness for both roughing and light finishing passes. Compatibility depends on form, relief angle, tolerance class, fastening method, size and thickness; the insert is supplied with a cylindrical hole to suit conventional clamping systems. Choosing the correct holder and mounting torque keeps the insert seated securely and reduces vibration, which in turn extends tool life and improves surface finish.

Practical advantages for workshop and production environments

The plate thickness of 4.76 mm and ISO designation ensure mechanical stability in demanding cut conditions. With no chipbreaker, selection of an appropriate cutting geometry and feed rate is key to achieving controlled chip formation; this approach is often preferred when bespoke chip management strategies are applied or when machining complex cast iron alloys. The ISO‑normed shape and clear specification simplify inventory management and make the insert a dependable choice for jobbing shops and production lines seeking reproducible results with minimal setup time.

FAQ

Is this insert suitable for finishing work in cast iron?
In many cases yes; the CNMA 090404 T515 insert (SKU 6760156‑Tungaloy) can be used for light finishing, though feed and depth of cut should be adapted to achieve the required surface finish.

Which holder type is required for the CNMA 090404 T515?
The insert is ISO‑normed and fits holders defined for CNMA‑type plates; selection of the correct holder must match form, relief angle, tolerance class, fastening and plate thickness.

Does the T515 grade perform well with interrupted cuts?
The CVD‑coated T515 grade is designed for stable chip formation and offers good performance under interrupted cutting typical of cast iron turning.

How does the absence of a chipbreaker affect machining?
With no chipbreaker on the plate, chip control relies on cutting parameters, tool overhang and the chosen holder; this can be advantageous where custom chip evacuation strategies are used.

What does the ISO code 090404 mean for this insert?
The ISO code indicates plate size and geometry; CNMA 090404 describes the rhombic shape, size 09 and the corner configuration — CNMA090404 T515 details can be cross‑referenced with holder specifications.
