Sandvik Coromant 5724281 Turning Insert Ccmt Coroturn 107

Product Description

The SANDVIK COROMANT 5724281 is a CCMT-style indexable turning insert in the CoroTurn 107 series, designed for external and internal turning operations on CNC and manual lathes. The insert features a TiAlN coating applied via PVD process over a solid carbide substrate, delivering a hard, heat-resistant surface well suited for finishing and semi-finishing cuts. Key geometry specs include an 80-degree diamond shape, a 3/8-inch inscribed circle, a 1/32-inch corner radius, and a 7-degree relief angle with a neutral hand orientation. The MM chip breaker geometry supports controlled chip formation in medium-depth turning passes.

This insert is intended for turning steel and stainless steel workpieces in production and job-shop environments. The CoroTurn 107 series is a widely used platform for both external turning and boring applications, particularly where screw-clamped toolholders are used. Typical users include CNC machinists and toolroom operators running finishing or light semi-finishing passes on ferrous materials. The manufacturer grade 1105 is positioned for steel and stainless steel at moderate cutting speeds where edge toughness and coating durability are priorities.

Key Features

• TiAlN coating via PVD process for heat resistance and extended edge life on ferrous materials
• 80-degree diamond insert shape (Shape Code C) provides a strong cutting edge suitable for general turning profiles
• MM chip breaker geometry designed for controlled chip evacuation during medium-depth turning cuts
• Neutral hand orientation — compatible with both right-hand and left-hand toolholder configurations
• Screw-clamped insert holding method for positive, repeatable seating in CoroTurn 107 compatible toolholders
• Two usable cutting edges per insert for cost-effective tooling usage

Compatibility

Designed for use in CoroTurn 107 series screw-clamped toolholders accepting CCMT insert geometry. ISO code CCMT 09 T3 08-MM 1105. Primary workpiece material is steel (ISO code P); secondary workpiece material is stainless steel (ISO code M).

Installation Notes

Indexable turning inserts should be installed and indexed by a qualified machinist using the correct torx or hex key as specified by the toolholder manufacturer — do not overtighten the clamping screw. Ensure the toolholder pocket and insert seat are clean and free of chips before seating the insert. Power down and lock out the machine before any insert change. Follow shop-specific cutting parameter guidelines for feed rate, depth of cut, and spindle speed appropriate to the workpiece material and machine capability.
