Sandvik Coromant 5909059 Turning Insert SNMG433-SMR 1105

Product Description

The SANDVIK COROMANT 5909059 is a solid carbide turning insert in the SNMG433-SMR 1105 configuration, designed for precision metal-turning operations on CNC lathes and turning centers. This insert carries a TiAlN coating applied via PVD process, delivering improved heat resistance and extended tool life in demanding cuts. The neutral hand orientation suits a wide range of toolholders and approach angles. With a 0.5-inch inscribed circle, a 3/64-inch corner radius, and a 55-degree included angle, it provides a well-defined cutting geometry optimized for controlled chip flow using the SMR chip breaker. Licensed HVAC techs and machinists running stainless steel and superalloy components will find this insert a reliable production-grade choice.

This turning insert is engineered primarily for stainless steel machining, with secondary suitability for superalloys and titanium workpiece materials. It belongs to the T-Max P series, which targets general-purpose and high-demand external and internal turning applications. The SMR chip breaker geometry is intended to manage stringy or tough chips common in stainless and superalloy cuts. The insert fits standard SNMG-style toolholders using clamp and pin holding methods, making it compatible with common tooling setups found in production and job-shop turning environments.

Key Features

• TiAlN coating via PVD process for elevated heat resistance and wear performance
• SMR chip breaker geometry designed to control chips in stainless steel and superalloy cuts
• 55-degree included angle square insert shape with 8 available cutting edges per insert
• 3/64-inch (0.0469-inch) corner radius for general finishing and semi-finishing passes
• Neutral hand orientation compatible with standard SNMG toolholder setups
• T-Max P series construction built for reliable performance in high-demand turning applications

Compatibility

Designed for use in standard SNMG-style turning toolholders utilizing clamp and pin holding methods. Suitable for CNC lathe and turning center applications machining stainless steel as the primary workpiece material, with secondary compatibility for superalloys and titanium. ISO code equivalent is SNMG120412-SMR 1105.

Installation Notes

Insert replacement and toolholder setup should be performed by a qualified machinist or tooling technician with the machine in a full stop and locked-out state per OSHA lockout/tagout procedures. Inspect the toolholder pocket and clamping components for wear or debris before seating the new insert. Verify clamp and pin holding hardware is undamaged and torqued per the toolholder manufacturer specification before resuming cuts. Do not run inserts beyond observable wear limits, as degraded edges increase cutting forces and risk workpiece damage.
