Sandvik Coromant 5734172 Turning Insert DNMG431-MF 1105

Product Description

The SANDVIK COROMANT 5734172 is a solid carbide turning insert in the DNMG431-MF 1105 designation, engineered for precision metal-turning operations on CNC lathes and turning centers. It features a 55-degree diamond shape (Insert Shape Code D), a Manufacturer Grade of 1105, and a TiAlN coating applied via PVD process for improved wear resistance and thermal stability. The MF chip breaker geometry is optimized for finishing and medium-duty cuts. With 4 cutting edges and a neutral hand orientation, this insert delivers consistent performance across multiple indexing positions. Licensed machinists and CNC operators working in production environments install and index this insert as part of routine tooling maintenance.

This insert is designed for primary use on steel workpieces and is also rated for secondary applications on stainless steel, superalloys, and titanium. The T-Max P series designation indicates suitability for external turning, facing, and profiling operations where controlled chip formation and surface finish consistency are priorities. It is typically used in medium-to-high production environments where tooling changeover speed and insert reliability directly affect cycle time and part quality.

Key Features

• DNMG insert style with 55-degree diamond geometry and 4 usable cutting edges

• MF chip breaker optimized for finishing and light-to-medium material removal rates
• Neutral hand orientation compatible with standard DNMG toolholders
• Clearance Code N and Tolerance Code M for precise seating and repeatable positioning
• Rated for steel, stainless steel, superalloy, and titanium workpiece materials (ISO Code P, M, S)

Compatibility

Designed for use in standard DNMG-style toolholders with clamp and pin insert-holding systems. ISO designation DNMG 15 04 04-MF 1105. Compatible with toolholders accepting a 0.5000-inch inscribed circle insert with a 0.2030-inch hole diameter. Verify toolholder specifications before ordering.

Installation Notes

Installation is performed by CNC machinists or tooling technicians. Power down and lock out the machine before indexing or replacing inserts. Use the correct clamping hardware specified for DNMG-style inserts with clamp and pin retention to ensure proper seating and torque. Inspect the toolholder pocket and seating surfaces for debris or wear before installing a new insert edge.
