Iscar 5606734 Milling Insert Htp Lnht 0604ER IC830 Carbide

Product Description

The ISCAR 5606734 is a solid carbide milling insert in the LNHT butterfly style, designed for high-performance tangential plunge milling operations. Manufactured in the IC830 grade and coated with an AlTiN and TiN multilayer finish applied via PVD process, this insert delivers thermal resistance and wear protection across demanding cutting applications. It features a negative rake geometry, a honed cutting edge, and four usable cutting edges per insert. The inscribed circle measures 0.1600 inches, thickness is 0.2670 inches, and the corner radius is 0.0315 inches. It is installed using a screw-holding method and is classified as a double-sided insert. Machinists and CNC tooling specialists working in job shops or production environments are the primary installers.

This insert is suited for milling steel, stainless steel, superalloys, and titanium workpieces — material application codes P, M, and S. It is rated for a maximum depth of cut of 0.3940 inches (4.50 mm) and an effective cutting edge length of 0.2559 inches. The right-hand configuration and ER chip breaker geometry make it appropriate for tangential plunge and shoulder milling passes where chip control and edge stability are priorities. Compatible with the HTP LN06 cutter series.

Key Features

• Four cutting edges per insert — double-sided design maximizes tool economy
• Butterfly (LNHT) insert shape with 90-degree included angle and negative rake
• Honed cutting edge style reduces microchipping on hard and abrasive workpiece materials
• ER chip breaker optimized for steel, stainless steel, superalloys, and titanium
• Screw-holding retention method for secure, repeatable seating in compatible toolholders

Compatibility

Compatible with the ISCAR HTP LN06 cutter series. ANSI code: HTP LNHT 0604 ER IC830. ISO code: HTP LNHT 0604 ER. Conforms to ANSI and ISO 13399 standards.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before seating or replacing inserts. Use the correct torx or hex key to torque the clamping screw to the toolholder specification — refer to the ISCAR HTP LN06 toolholder documentation for fastener torque values. Inspect the insert pocket for chips or debris before seating a new insert to ensure proper contact and runout.
