Iscar 5601634 Milling Insert Apkt 100308PDTR-RM IC328

Product Description

The ISCAR 5601634 is a solid carbide milling insert carrying the ANSI designation APKT 100308PDTR-RM in grade IC328. It is a parallelogram-shaped, single-sided insert with a positive rake geometry and an 85-degree included angle. The TiCN coating is applied via PVD process, which delivers a hard, wear-resistant surface well suited for high-speed milling of ferrous and difficult-to-machine materials. With two cutting edges, a corner radius of 0.0315 inches (1/32 inch), and a maximum depth of cut of 0.3860 inches, this insert is designed for productive face and shoulder milling operations. Installation is by screw-clamp holding. Licensed machinists and tooling technicians are the primary users.

This insert is intended for milling steel, stainless steel, superalloys, and titanium in both production and job-shop environments. It carries material grade designations C2, C3, C5, and C6, and is compliant with ANSI and ISO 13399 standards. The RM chip breaker geometry and chamfered-and-honed cutting edge style promote controlled chip flow and reduce cutting forces, making this insert effective across a range of axial and radial engagement conditions typical in roughing and semi-finishing milling passes. Right-hand cutting orientation applies.

Key Features

• Solid carbide substrate with PVD TiCN coating for wear resistance in steel and stainless steel applications
• Parallelogram insert shape (APKT style) with positive rake and 11-degree relief angle
• RM chip breaker with chamfered and honed cutting edge for controlled chip formation
• Two usable cutting edges per insert; right-hand orientation
• Maximum depth of cut: 0.3860 inches (8.00 mm)
• Compliant with ANSI and ISO 13399 standards; UNSPSC code 23291601

Compatibility

Designed for use in the ISCAR HELIMILL series, specifically compatible with HM90-10 cutter bodies. Verify cutter body pocket geometry and screw size before installation.

Installation Notes

This insert is seated and secured by a clamping screw; use the manufacturer-specified torx or hex key to achieve proper seating without overtightening. Power down and lock out the machine spindle before changing inserts. Inspect the pocket seating surface and shim for damage or chips before installing a new insert. Improper seating can cause premature edge failure or workpiece damage.
