DPMT11T308 11T308 T9215 DPMT Turning insert — Tungaloy

A DPMT11T308 T9215 indexable turning insert engineered for medium-steel machining, offering a rhombic geometry with 11° relief and a secure cylindrical hole with single-sided countersink.

• CVD-coated carbide grade T9215
• Optimised for medium steel machining
• Rhombic 11 mm insert with 0.8 mm radius
• Cylindrical hole with 40°–60° countersink

Maximised productivity for medium-steel turning

The combination of CVD-coated carbide and the T9215 grade provides a balanced mix of wear resistance and fracture toughness, specifically selected for medium-steel applications. This results in a longer useful life under continuous and light-interrupted cuts, enabling higher throughput and fewer insert changes. The chip control delivered by the one-sided chipbreaker reduces rework and improves surface consistency, which in turn supports a more predictable production rhythm and lower overall machining costs.

Precise geometry for stable cutting and straightforward holder matching

A rhombic cutting form with an 11° relief and a 55° geometry angle gives reliable cutting engagement and predictable tool behaviour. Holder compatibility is determined by insert form, relief angle, tolerance class, attachment style, size and thickness; choosing an ISO-standard holder ensures correct seating and minimises runout. The insert integrates seamlessly into a system comprising an ISO indexable insert, a matching outer holder or boring bar, shim/clamping set and the appropriate replacement screws, simplifying toolroom logistics and set-up time.

Practical features that streamline workshop use

The insert’s 0.8 mm corner radius and 3.97 mm plate thickness suit finishing and light roughing operations, while the cylindrical hole with a 40°–60° single-sided countersink secures a positive clamp force and precise repeatability during index changes. As part of the ISO series, the component benefits from established interchangeability and clear specification standards, reducing the need for bespoke tooling and enabling rapid replacement. These practical details contribute to reduced downtime and consistent process reliability on production lines.

FAQ

What materials is this insert suitable for?
The DPMT11T308 T9215 insert is optimised for medium-steel machining and delivers a balance of wear resistance and toughness for continuous and slight interrupted cuts.

How does holder compatibility work for this insert?
Compatibility depends on insert form, relief angle, tolerance class, attachment, size and thickness; fitting the insert to an ISO-compliant outer holder or boring bar ensures correct seating and repeatability.

What is the purpose of the single-sided chipbreaker?
The one-sided chipbreaker on this insert assists chip control in medium-steel operations, promoting consistent surface finish and reducing the risk of built-up edge.

Is the corner radius suitable for finishing?
Yes, the 0.8 mm corner radius provides a good compromise between finishing capability and strength for light roughing, offering improved surface results on steel components.

How is the insert fixed into the holder?
Fixing is via a cylindrical hole with a single-sided countersink (40°–60°), allowing secure clamping and accurate repositioning during index changes.
