Sandvik Coromant 7080836 Turning Insert DNMG441-PM 4335

Product Description

The SANDVIK COROMANT 7080836 is a DNMG-style indexable turning insert in the T-Max P series, designed for external turning operations on steel workpieces. It carries manufacturer grade 4335 and is CVD-coated with a TiCN, Al2O3, and TiN multilayer coating system that provides wear resistance and thermal stability at the cutting edge. The insert features a 55-degree diamond shape (insert shape code D), a neutral hand orientation, and a PM chip breaker geometry suited for medium to general-purpose steel turning. With four usable cutting edges per insert, it delivers a reliable cost-per-edge ratio in production turning environments. Licensed machinists and CNC lathe operators are the primary installers and users.

This insert is applied in external turning of steel components, covering a broad range of primary workpiece materials classified under ISO code P. The T-Max P series is engineered for steel turning across light finishing to medium roughing passes depending on feed and depth-of-cut selection. The ISO designation for this insert is DNMG 15 06 04-PM 4335, which identifies it within international tooling catalogs and makes cross-referencing to compatible toolholders straightforward. Typical applications include shaft turning, facing, and profiling on CNC lathes and turning centers in job shop and production environments.

Key Features

• CVD multilayer coating: TiCN, Al2O3, and TiN for extended tool life in steel turning
• 55-degree diamond insert shape with four cutting edges per insert
• PM chip breaker geometry optimized for medium-duty steel turning
• Neutral hand orientation for flexible toolholder compatibility
• Clamp and pin insert holding method for secure seating under cutting loads
• ISO code DNMG 15 06 04-PM 4335 for direct catalog cross-reference

Compatibility

Designed for use in DNMG-style toolholders that accept a 1/2 inch inscribed circle, 55-degree diamond insert with clamp and pin holding. Compatible toolholders must conform to ISO tolerance code M and clearance code N (DNMG designation). Refer to the T-Max P toolholder series for confirmed fitment.

Installation Notes

Insert replacement and indexing should be performed by a qualified machinist with the machine fully stopped and the spindle locked. Use the appropriate torque wrench and clamp hardware specified by the toolholder manufacturer when securing the insert. Inspect the insert pocket and seating surfaces for chips or debris before seating a new edge. Follow the cutting parameter recommendations in the SANDVIK COROMANT T-Max P catalog for feed rate, depth of cut, and cutting speed to avoid premature edge wear or breakage.
