Sandvik Coromant 5742773 Milling Insert Grade 4030 R215.44

Product Description

The SANDVIK COROMANT 5742773 is a solid carbide milling insert in grade 4030, designed for use in the R215.44 insert series. It carries a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, which provides thermal resistance and wear protection during interrupted and continuous milling operations. The insert measures 3.96 mm (0.1563 inches) thick with an inscribed circle of 0.3740 inches and features a 0.80 mm (0.0315 inch) corner radius. It is a parallelogram-shaped, single-sided insert with a positive rake geometry and a corner-rounded cutting edge style. Licensed machinists, CNC operators, and tool room technicians install and index this insert in compatible milling toolholders.

This insert is suited for milling steel and cast iron workpieces, corresponding to ISO material codes P and K. The R215.44 series designation and insert size code 15T308 identify its seating geometry. The WL chip breaker geometry controls chip flow during face milling and shoulder milling applications in both roughing and finishing passes. It is a right-hand insert held in place by a screw-lock method. Maximum depth of cut reaches 0.5906 inches, making it appropriate for moderate material removal rates on ferrous workpieces in production and job shop environments.

Key Features

• Grade 4030 solid carbide substrate with CVD multilayer TiCN, Al2O3, and TiN coating for wear and heat resistance
• Parallelogram insert shape with positive rake and corner-rounded cutting edge for smooth entry and reduced cutting forces
• 0.80 mm corner radius (0.0315 inches) provides edge strength while maintaining surface finish quality
• WL chip breaker geometry for controlled chip evacuation on steel and cast iron
• Screw-lock insert holding method for secure, repeatable indexing
• Compliant with both ANSI and ISO standards; ANSI/ISO code R215.44-15T308M-WL 4030

Compatibility

Designed for use in R215.44 series milling toolholders accepting insert size code 15T308. Compatible with steel and cast iron workpiece materials (ISO P and K classifications). Catalog number R215.44-15T308M-WL 4030 confirms toolholder seat geometry and insert pocket requirements.

Installation Notes

This insert is installed and indexed by a licensed machinist or CNC tool room technician. Power down and lock out the machine spindle before removing or indexing any insert. Use the appropriate Torx or hex key specified by the toolholder manufacturer to seat the clamping screw - do not overtighten. Inspect the insert pocket and seating surfaces for chips or debris before installing a new insert to ensure proper seating and runout control.
