Kennametal 5665818 Milling Insert ODMT040408EN412 SP6519

Product Description

The KENNAMETAL 5665818 is a solid carbide milling insert carrying ANSI and ISO designation ODMT040408EN412 in grade SP6519. It features a TiAlN coating applied via PVD process, an octagon insert shape with 8 cutting edges, and a positive rake geometry with a 15-degree relief angle. The inscribed circle measures 0.5039 inches and the insert thickness is 0.1870 inches. A honed cutting edge style and 0.0312-inch corner radius (1/32 inch) support controlled engagement and edge stability during milling operations. This insert is installed by machinists and tooling technicians in production and job-shop environments.

This insert is designed for milling steel, stainless steel, superalloys, and titanium workpieces, corresponding to material codes P, M, and S. It is a neutral-hand, single-sided insert secured by screw-holding method and is compatible with the 7745VOD04 cutter series. The 412 chip breaker geometry is suited to the cutting conditions typical of these demanding workpiece materials. It conforms to both ANSI and ISO standards and carries UNSPSC code 23291601.

Key Features

• Octagon insert shape with 8 cutting edges maximizes usable edge count per insert
• 15-degree relief angle and positive rake geometry reduce cutting forces
• Honed cutting edge style provides controlled edge preparation for consistent performance
• 0.0312-inch corner radius balances surface finish and edge strength
• Screw-held, neutral-hand design fits the 7745VOD04 cutter series

Compatibility

Compatible with the Kennametal 7745VOD04 cutter series. ANSI and ISO code ODMT040408EN412. Intended for milling steel, stainless steel, superalloys, and titanium workpieces (material codes P, M, S).

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Always power down and lock out the machine spindle before seating or replacing inserts. Use the appropriate torx or hex key to secure the clamping screw to the cutter body per the toolholder manufacturer specifications. Inspect the pocket seating surface for chips or debris before installing a new insert to ensure proper seating and prevent premature edge failure.
