Sandvik Coromant 5909004 Turning Insert DNGG432SGF H13A

Product Description

The SANDVIK COROMANT 5909004 is a carbide turning insert in the T-Max P series, designed for precision metal cutting on CNC lathes and turning centers. It features an uncoated bright finish with an H13A carbide grade, a 55-degree diamond insert shape, and an SGF chip breaker geometry. The inscribed circle measures 12.70 mm (0.500 inches), insert length is 15.50 mm (0.610 inches), and the corner radius is 0.80 mm (1/32 inch). With four available cutting edges and a neutral hand orientation, this insert delivers consistent performance in demanding turning applications.

This insert is engineered primarily for turning stainless steel and is also rated for use on superalloys and titanium. It is suited for finishing and semi-finishing operations where tight tolerances and controlled chip formation are critical. The SGF chip breaker geometry is optimized for low-to-medium feed rates on difficult-to-machine materials. Machinists and CNC operators working in aerospace, medical, and industrial manufacturing will find this insert appropriate for applications requiring reliable edge stability and dimensional consistency on challenging workpiece materials.

Key Features

• H13A uncoated carbide grade engineered for stainless steel, superalloy, and titanium workpieces
• 55-degree diamond insert shape (DNGG style) with four cutting edges for extended tool life per insert
• SGF chip breaker geometry optimized for controlled chip formation at low-to-medium feeds
• 0.80 mm corner radius provides a balance between edge strength and surface finish quality
• Neutral hand orientation allows use in both right-hand and left-hand toolholders
• Clamp and pin holding method compatible with standard T-Max P toolholder systems

Compatibility

Designed for use with SANDVIK COROMANT T-Max P series toolholders that accept DNGG-style inserts with a 0.500-inch inscribed circle. ISO code DNGG150408SGFH13A. Compatible with toolholder systems designed for clamp and pin insert retention.

Installation Notes

This insert should be installed by a qualified machinist or CNC tooling technician following the toolholder manufacturer's seating and clamping procedures. Power down and lock out the machine spindle before changing inserts. Use appropriate insert-handling tools to avoid contact with cutting edges. Verify correct seating against the toolholder pocket before initiating a cut to prevent insert movement or premature failure.
