Sandvik Coromant 5909076 Turning Insert Snmg H13A Carbide

Product Description

The SANDVIK COROMANT 5909076 is an uncoated solid carbide turning insert in the SNMG style, part of the T-Max P series. It features a 55-degree included angle, a 3/4-inch inscribed circle, and a 1/16-inch corner radius, making it a precision insert for demanding turning operations. The insert uses an SMR chip breaker geometry and carries a Manufacturer Grade of H13A. With 8 cutting edges and a neutral hand orientation, it delivers consistent performance in high-volume production environments. Licensed HVAC technicians, machinists, and tool cribs working in metalworking and precision manufacturing specify this insert for finishing and semi-finishing passes.

This insert is designed primarily for turning stainless steel, with secondary suitability for superalloys and titanium. The SMR chip breaker geometry and H13A uncoated carbide grade are optimized for these difficult-to-machine materials where edge sharpness and heat resistance are critical. It fits into SNMG-compatible toolholders using clamp and pin holding methods. Typical applications include OD turning on CNC lathes in job shops, aerospace component machining, and medical part production where surface finish and dimensional accuracy are essential.

Key Features

• Uncoated H13A solid carbide grade for sharp, consistent edge performance on stainless steel and superalloys
• SMR chip breaker geometry optimized for stainless steel, titanium, and superalloy turning
• 8 cutting edges per insert for extended tool life and lower cost per edge
• Neutral hand orientation for flexible toolholder compatibility
• Clamp and pin holding method for secure, repeatable seating in the pocket
• Part of the T-Max P series, engineered for external turning on CNC and manual lathes

Compatibility

Designed for use in SNMG-style turning toolholders that accept clamp and pin holding. Compatible with toolholder pockets sized for a 3/4-inch inscribed circle SNMG insert with a 0.3120-inch hole diameter. ISO designation SNMG190616-SMR H13A. Verify toolholder pocket geometry and clamping system before installation.

Installation Notes

Insert installation and indexing should be performed by a qualified machinist with the machine powered down and spindle locked. Seat the insert fully in the pocket before tightening the clamping pin to ensure proper support and prevent edge chipping. Inspect the toolholder pocket for wear or debris before seating a new insert. Follow the toolholder manufacturer specifications for clamping torque and pocket condition.
