Iscar 5601934 Milling Insert Spkr 1203EDTR IC910 Carbide

Product Description

The ISCAR 5601934 is a solid carbide milling insert carrying the SPKR 1203EDTR designation and manufactured to the IC910 grade. It is a square-shaped, single-sided insert with a 0.5-inch inscribed circle and 0.125-inch thickness, featuring an AlTiN coating applied via PVD process. The insert is designed for use in milling operations on steel and cast iron workpieces. It carries a positive rake geometry and a T-Land cutting edge style that helps manage chip flow and cutting forces during face and shoulder milling. A licensed machinist or CNC setup technician typically specifies and installs this insert in production or job-shop milling applications.

This insert is suited for face milling and shoulder milling operations on ferrous materials including steel and cast iron. It fits the ISCARMILL F75 cutter series and conforms to ANSI code SPK 42EDTR IC910 and ISO code SPKN 1203EDTR. The right-hand cutting orientation and four available cutting edges make it a practical choice for medium to high-production milling setups where consistent tool life and repeatable surface finish are priorities. Applications span both roughing and semi-finishing passes depending on depth of cut and feed rate selection.

Key Features

• IC910 grade solid carbide with AlTiN PVD coating for wear resistance on steel and cast iron
• Square insert shape with 4 cutting edges, maximizing cost-per-edge value
• Positive rake geometry with T-Land cutting edge style for controlled chip formation
• Maximum depth of cut of 0.374 inches (9.50 mm) for flexible milling passes
• Single-sided, right-hand insert held by clamp in the cutter body
• Conforms to ANSI and ISO 13399 standards for straightforward cross-referencing

Compatibility

Compatible with the ISCARMILL F75 cutter series. Conforms to ANSI code SPK 42EDTR IC910 and ISO code SPKN 1203EDTR. Rated for material grades C2, C3, and C6 workpiece materials covering steel and cast iron applications.

Installation Notes

This insert is installed and indexed by a machinist or CNC tooling technician. Power down and lock out the machine spindle before changing or indexing inserts. Use the appropriate torque wrench and clamping hardware specified by the cutter body manufacturer to seat the insert correctly. Inspect the insert pocket for chips or debris before seating a new edge to ensure proper contact and prevent premature insert failure.
