Sandvik Coromant 5737127 Grooving Insert H13A Solid Carbide

Product Description

The SANDVIK COROMANT 5737127 is a solid carbide grooving insert designed for precision parting and grooving operations on CNC lathes and turning centers. Manufactured to the N151.2 insert style with an H13A uncoated carbide grade, this insert delivers a 0.125 inch cutting width and a neutral hand orientation. The 4G chip breaker geometry promotes controlled chip evacuation during grooving passes. With a rake angle of 7 degrees and a corner radius of 0.0075 inches, this insert is suited for applications demanding accurate groove geometry and a clean finish in ferrous and non-ferrous materials.

This insert is part of the T-Max Q-Cut series, which targets grooving, parting, and face grooving on turning equipment. Typical install scenarios include production turning on medium to small diameter workpieces where consistent groove width and surface finish are critical. The uncoated H13A carbide grade performs reliably at moderate cutting speeds and is commonly applied when coating would interfere with dimensional tolerance requirements or when machining materials sensitive to built-up edge. The insert seat size is 25, matching the corresponding T-Max Q-Cut toolholders designed for that seat designation.

Key Features

• Solid carbide H13A uncoated grade for consistent performance in precision grooving applications
• 0.125 inch cutting width with neutral hand orientation for straight grooving and parting
• 4G chip breaker geometry for controlled chip formation and evacuation
• 7-degree rake angle supports efficient cutting action and reduced cutting forces
• Corner radius of 0.0075 inches (min 0.0055 inches, max 0.0095 inches) for defined groove edge geometry
• ISO code N151.2-A125-25-4G H13A for direct cross-reference to SANDVIK COROMANT tooling catalogs

Compatibility

Designed for use with T-Max Q-Cut series toolholders accepting insert seat size 25 and the N151.2 insert style. The ISO designation N151.2-A125-25-4G H13A can be used to verify holder compatibility in the SANDVIK COROMANT tooling system.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician with the machine spindle fully stopped and all energy sources locked out per site lockout/tagout procedures. Seat surfaces on the toolholder should be clean and free of chips or debris before seating the insert. Use the correct torque wrench and clamping screw specified for the T-Max Q-Cut holder to avoid cracking the carbide. Do not use this insert beyond its stated cutting width or apply side loads outside the design parameters of the N151.2 system.
