Iscar 5694945 Milling Insert Apkt 100310PDR-RM IC328

Product Description

The ISCAR 5694945 is a solid carbide milling insert carrying the ANSI designation APKT 100310PDR-RM in grade IC328. It is a single-sided, right-hand, parallelogram-shaped insert with a positive rake geometry and an 11-degree relief angle. The TiCN coating is applied via PVD process, providing wear resistance suited for demanding milling operations. With a corner radius of 0.0394 inches (1.00 mm) and a chamfered and honed cutting edge style, this insert delivers controlled chip formation and edge stability. It is installed by machinists and tooling technicians working with indexable milling cutters in production and job-shop environments.

This insert is designed for milling steel, stainless steel, superalloys, and titanium, corresponding to material grade classifications C2, C3, C5, and C6 (ISO P, M, and S workpiece material codes). It belongs to the HELIMILL series and is compatible with HM90-10 cutter bodies. The RM chip breaker geometry supports efficient chip evacuation across a range of depths of cut up to 0.386 inches (8.00 mm). Typical applications include face milling, shoulder milling, and general-purpose indexable milling in both roughing and semi-finishing passes on ferrous and exotic alloy workpieces.

Key Features

• Solid carbide substrate with PVD-applied TiCN coating for extended tool life on steel and stainless steel
• Positive rake, 11-degree relief angle geometry reduces cutting forces and heat generation
• RM chip breaker for reliable chip control across varying feed and depth conditions
• Corner radius of 0.0394 inches (1.00 mm) with chamfered and honed cutting edge for edge security
• Right-hand, single-sided insert with screw-holding method for repeatable positioning
• Rated for maximum depth of cut of 0.386 inches (8.00 mm) with 2 cutting edges per insert

Compatibility

Designed for use with ISCAR HELIMILL series HM90-10 cutter bodies. Conforms to ANSI and ISO 13399 standards under the designation APKT 100310PDR-RM IC328. Suited for machining steel, stainless steel, superalloys, and titanium workpieces.

Installation Notes

Installation is performed by a qualified machinist or tooling technician. Power down and lock out the machine spindle before indexing or replacing inserts. Secure the insert using the appropriate torx or hex key for the cutter body screw per the cutter manufacturer's tooling manual. Inspect the insert pocket seating surface for chips or debris before seating a new insert to ensure proper contact and runout.
