CCMT 09T308 AH6235 CCMT turning insert by Tungaloy — PVD-coated carbide, 0.8 mm radius

CCMT09T308 AH6235 is a rhombic turning insert designed for general external and internal turning, optimised for interrupted cuts and challenging stainless steel applications

• ISO rhombic CCMT insert
• PVD-coated carbide AH6235
• 0.8 mm nose radius, 7° clearance
• Cylindrical hole with countersink

Reliable chip control for challenging interrupted cuts

The PVD-coated AH6235 grade is formulated as a tougher carbide to resist edge fracture during intermittent cuts and unstable conditions. Combined with a single-sided chipbreaker, this insert reduces the risk of built-up edge and sudden breakouts, which leads to more consistent cycle times and fewer unexpected re‑changes. For components in stainless or hard-to-machine alloys, the grade and geometry provide a measured balance between edge strength and finish quality, helping to maintain process stability under variable cutting conditions.

Accurate seating and compatibility for repeatable results

Designed to the ISO series dimensions, the rhombic geometry and the standard form ensure straightforward compatibility with a broad range of external holders and boring bars. The insert’s 7° clearance, 80° included angle and 3.97 mm thickness contribute to secure clamping and reduced vibration when mounted correctly. Knowing these parameters simplifies holder selection: match the form, tolerance class, fastening method, size and thickness to achieve repeatable tool positioning and dimensional stability on successive parts.

Durable coating and cost‑effective tool life

The PVD coating applied to the carbide substrate increases resistance to abrasion and minimizes microchipping on the cutting edge, particularly when machining stainless steels. This improved resistance translates into longer intervals between indexings and replacements, lowering tool consumption per component and supporting a more economical production flow. The reinforced edge toughness of the AH6235 grade also helps to protect the tool during brief encounters with inclusions or interrupted cuts, reducing scrap and rework.

System guidance for straightforward integration

Integration into an existing tooling system is simple: the insert forms part of a modular setup that includes a matching outer holder or boring bar, a clamping shim and a suitable screw set. The cylindrical hole with one-sided countersink (40°–60°) provides stable centring and repeatable fixation in friction clamp systems. Select the chipbreaker and grade according to the workpiece material and machine stability to achieve the best balance between surface finish and tool life; small adjustments to feed and depth of cut often yield significant improvements in process reliability.

FAQ

What materials is this insert best suited for? The AH6235 grade is intended for tougher workpieces and is particularly suitable when machining stainless steels and materials prone to edge breakout; the CCMT09T308 insert shows good resistance to chipping in interrupted cuts.

How does the plate geometry affect holder choice? Compatibility depends on form, clearance, tolerance class, fastening and thickness; the ISO rhombic shape and 3.97 mm thickness of this insert allow use with standard CCMT-compatible external holders and boring bars.

Is the CCMT09T308 AH6235 suitable for finishing operations? Yes, when combined with an appropriate feed and cutting speed the PVD-coated grade and 0.8 mm nose radius can deliver acceptable surface quality for many finishing tasks.

What is the benefit of the cylindrical hole with countersink? The cylindrical hole with one-sided countersink (40°–60°) ensures secure seating and repeatable clamping, improving stability and reducing the risk of insert rotation under load.

How should the chipbreaker be selected for a specific job? Select the chipbreaker based on workpiece material, depth of cut and machine stability; the single-sided chipbreaker on this insert is aimed at improving chip control in interrupted and unstable cutting conditions.
