Iscar 5606393 HM90 Apkt 1003PDR IC808 Milling Insert

Product Description

The ISCAR 5606393 is a solid carbide milling insert carrying the ANSI designation HM90 APKT 1003PDR in the IC808 manufacturer grade. It is a single-sided, right-hand, parallelogram-style insert with a positive rake geometry and a honed cutting edge, designed for use in indexable milling cutters. The insert measures 0.139 inches thick and 0.266 inches wide, with a corner radius of 0.0315 inches. It is PVD-coated with a Sumotec multilayer TiAlN, AlTiN, and TiN coating applied over a submicron solid carbide substrate. Licensed machinists and CNC tooling technicians install this insert in compatible HM90-10 series milling bodies.

This insert is designed for medium to high-speed milling applications across a wide range of workpiece materials, including steel, stainless steel, cast iron, superalloys, titanium, and hard materials. It fits into the HELI2000 series tooling platform and is suited for both roughing and finishing passes where reliable edge life and thermal resistance are required. The maximum depth of cut is 0.386 inches, and the effective cutting edge length is 0.404 inches, making it appropriate for shoulder milling, face milling, and pocket milling operations on CNC machining centers in production environments.

Key Features

• Submicron solid carbide substrate in IC808 grade for toughness and wear resistance
• Sumotec PVD multilayer coating: TiAlN, AlTiN, and TiN for thermal and oxidation resistance
• Positive rake geometry with honed cutting edge reduces cutting forces
• PDR chip breaker for effective chip control across varied materials
• Two cutting edges per insert; right-hand orientation; screw-clamped holding method
• Maximum depth of cut of 0.386 inches; effective cutting edge length of 0.404 inches
• Conforms to ANSI and ISO 13399 standards

Compatibility

Designed for use with HM90-10 series cutter bodies. ANSI code: HM90 APKT 1003PDR IC808. ISO code: HM90 APKT 1003PDR. Confirmed compatible cutter series: HM90-10.

Installation Notes

Installation is performed by machinists or CNC tooling technicians. Always power down and lock out the spindle before seating or indexing inserts. Use the manufacturer-specified torx or hex key to drive the clamping screw to the correct seating without overtightening, which can crack the insert or damage the pocket. Inspect the insert pocket and seating surface for chips or debris before installing a new insert.
