Horn 313454500TN35 Milling Insert TN35 Solid Carbide

Product Description

The HORN 313454500TN35 is a solid carbide milling insert designed for use in precision milling applications across a wide range of workpiece materials. Carrying the TN35 manufacturer grade, this single-sided, right-hand insert features a TiN coating applied via PVD process, which enhances surface hardness and wear resistance. With a positive rake geometry and three cutting edges, the insert delivers controlled chip formation and extended tool life. It measures 0.28 inches thick with a 0.8540-inch inscribed circle and belongs to the Series 313 product family. Licensed machinists and tooling technicians working in production or job-shop environments are the primary installers of this type of insert.

This insert is suited for milling hard materials, cast iron, stainless steel, non-ferrous metals, steel, and superalloys including titanium. The positive rake geometry makes it particularly effective where cutting forces need to be minimized, such as when machining difficult-to-cut materials or thin-walled workpieces. The screw-holding method provides secure clamping in compatible Series 313 toolholders, maintaining insert position under interrupted cuts and high-feed conditions. It is appropriate for both roughing and finishing passes depending on depth of cut and feed rate selection.

Key Features

• Solid carbide construction with TiN PVD coating for enhanced wear resistance
• Three cutting edges on a single-sided insert design for consistent indexing
• Positive rake angle reduces cutting forces on difficult workpiece materials
• Screw-clamp holding method for rigid, repeatable insert seating
• Right-hand cutting orientation with 45-degree included angle geometry
• Compatible with hard materials, cast iron, stainless steel, non-ferrous metals, steel, and superalloys and titanium

Compatibility

Designed for use with HORN Series 313 milling toolholders that accept screw-clamped inserts with an insert size code of 4545 and a right-hand cutting orientation.

Installation Notes

Insert indexing and replacement should be performed by a qualified machinist or tooling technician with the machine powered down and in a locked-out, tagged-out state. Use the appropriate torx or hex key specified by the toolholder manufacturer when tightening the clamping screw - do not overtighten, as this can fracture the carbide insert. Inspect the insert pocket and clamping screw for wear or debris before seating a new insert. Consult the toolholder manufacturer documentation for recommended torque values and seating procedures.
