Sandvik Coromant 5752470 TCMT221-MF 1105 Turning Insert

Product Description

The SANDVIK COROMANT 5752470 is a TCMT-style triangular carbide turning insert in the CoroTurn 107 series, grade 1105, with a TiAlN PVD coating applied for wear resistance and thermal stability. The insert features a neutral hand orientation, a 60-degree included angle, a 1/4-inch inscribed circle, and a 1/64-inch corner radius. It measures 0.4071 inches in length and 0.125 inches thick. The MF chip breaker geometry is engineered for light to medium finishing cuts, making it a practical choice for machinists running turning operations on CNC lathes and manual turning centers.

This insert is suited for turning steel as its primary workpiece material, with secondary capability across stainless steel, superalloys, and titanium. The CoroTurn 107 series is designed for internal and external turning applications in both roughing and finishing scenarios, though the MF chip breaker geometry is best matched to finishing passes. Screw-type insert holding is used, which requires a compatible toolholder with the appropriate pocket and clamping screw. Typical users include CNC machinists and toolroom operators in production and job-shop environments.

Key Features

• TiAlN coating applied via PVD process for thermal and abrasion resistance
• Grade 1105 carbide substrate suited for steel and multi-material turning
• MF chip breaker geometry optimized for finishing operations
• Triangular insert shape provides 3 usable cutting edges per insert
• Screw-type mounting with 0.1102-inch hole diameter for positive insert location
• Neutral hand orientation for flexible toolholder pairing

Compatibility

Compatible with CoroTurn 107 series toolholders designed for TCMT-style screw-on inserts with a 1/4-inch inscribed circle. ISO designation TCMT 11 03 04-MF 1105. Verify toolholder pocket specifications and clamping screw size before installing.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Power down and lock out the machine spindle before changing inserts. Use the correct Torx or hex key to seat the clamping screw to the toolholder manufacturer's recommendation — do not overtighten, as this can crack the insert or damage the pocket seat. Inspect the toolholder pocket for chips or debris before seating the new insert to ensure full, flat contact.
