Sandvik Coromant 5915061 Turning Insert DNMG432-SM 1105

Product Description

The SANDVIK COROMANT 5915061 is a DNMG432-SM 1105 series turning insert designed for precision metal cutting on CNC and manual lathes. Built from solid carbide with a PVD-applied TiAlN coating, this insert delivers thermal resistance and edge wear performance in demanding turning operations. The neutral hand orientation suits a wide range of tool holders. Key dimensions include a 0.5 inch inscribed circle, a 0.252 inch insert length, and a 1/32 inch (0.0313 inch) corner radius. The SM chip breaker geometry is engineered to manage chip flow and reduce cutting forces during finish and semi-finish passes.

This insert is intended for turning stainless steel as its primary workpiece material, with secondary applications in superalloys and titanium. It belongs to the SANDVIK COROMANT T-Max P series, a line developed for external and internal turning with consistent dimensional accuracy. Typical users are CNC machinists and tooling specialists working in aerospace, medical, and energy sector machining environments where tight tolerances and difficult-to-machine alloys are standard. The ISO designation for this insert is DNMG 15 04 08-SM 1105.

Key Features

• PVD TiAlN coating provides oxidation resistance and extends edge life in stainless steel and superalloy cuts
• SM chip breaker geometry controls chip formation during finish to semi-finish turning passes
• 55-degree diamond insert shape (D) enables access to tight geometries and contour turning
• 4 cutting edges per insert for extended tooling value per unit
• Clamp and pin holding method for rigid, repeatable seating in compatible tool holders
• Neutral hand orientation compatible with right- and left-hand turning setups

Compatibility

Designed for use in T-Max P series turning tool holders that accept DNMG insert style with clamp and pin holding. Compatible holders must accommodate a 0.203 inch hole diameter and DNMG 15 04 08 insert geometry. Refer to SANDVIK COROMANT tooling catalogs to confirm specific holder compatibility before use.

Installation Notes

Insert seating and clamping should be performed by a qualified CNC machinist or tooling technician following the tool holder manufacturer's specified torque and clamping procedures. Power down and lock out the machine spindle before changing inserts. Inspect the insert pocket and clamping components for wear or debris before seating a new insert. Verify correct insert orientation and chip breaker direction relative to the cutting direction before resuming operation.
