Horn L314603200AS45 Milling Insert Solid Carbide AS45

Product Description

The HORN L314603200AS45 is a solid carbide milling insert engineered for demanding metal removal applications. Part of the L314 series, this single-sided insert features a positive rake geometry and a left-hand orientation. It carries the AS45 manufacturer grade and provides three cutting edges per insert, improving cost-per-edge efficiency. The corner radius measures 0.20 mm (approximately 0.008 inches). Screw-held mounting keeps the insert securely seated in compatible toolholders during high-feed and interrupted-cut operations. Machinists and CNC operators working in production environments will find this insert suited to a wide range of workpiece materials.

This insert is designed for milling cast iron, steel, stainless steel, superalloys, titanium, and non-ferrous metals, covering ISO material groups P, M, K, S, and N. The AS45 grade and positive rake geometry make it a practical choice for both roughing and semi-finishing passes where controlled chip formation and edge stability are priorities. Typical applications include face milling, shoulder milling, and contour milling on CNC machining centers in industrial and job-shop environments.

Key Features

• AS45 manufacturer grade solid carbide construction for extended tool life across multiple material groups
• Positive rake geometry reduces cutting forces and improves chip evacuation
• Three cutting edges per insert for improved cost-per-edge value
• Left-hand insert orientation for dedicated left-hand toolholder configurations
• 0.20 mm corner radius for controlled surface finish and edge strength
• Screw-held clamping method for secure, repeatable seating in the toolholder pocket

Compatibility

Designed for use with HORN L314 series toolholders that accept left-hand, screw-clamped milling inserts in insert size code 0320. Verify toolholder pocket geometry and hand orientation before installation.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Power down and lock out the machine spindle before changing inserts. Use the correct torx or hex key specified by the toolholder manufacturer to tighten the clamping screw - do not overtighten, as this can crack the carbide body. Inspect the toolholder pocket for wear, chips, or debris before seating the insert.
