Iscar 3104505 Square-shoulder Face Mill 2.5in Tangplunge

Product Description

The ISCAR 3104505 is an indexable square-shoulder face mill designed for precision milling operations in metal cutting environments. Built around the TangPlunge series platform, this cutter accepts five HTP LNHT 1606 style inserts held in place by a clamp and screw method. It delivers a maximum cutting diameter of 2.5 inches, a maximum depth of cut of 0.118 inches, and operates at a 0/90 degree lead angle for true 90-degree shoulder milling. Through-coolant capability helps manage heat and chip evacuation at the cutting zone. Right-hand cutting direction is standard. Licensed machinists and CNC operators are the typical end users for this tooling.

This face mill is suited for square-shoulder profiling and face milling on machining centers and CNC mills where ISO-standard tooling is specified. The 1.0 inch arbor hole diameter fits common arbor and adapter configurations used in production and job-shop environments. The TangPlunge series is engineered for tangential insert clamping, which distributes cutting forces across the wider insert face to extend edge life during aggressive shoulder milling passes. The 2.5 inch cutting diameter makes it well-suited for smaller spindle bores and compact workpiece features.

Compatibility

Compatible with HTP LNHT 1606 inserts. Cutter style designation is HTP-R-LN16. Verify arbor and adapter compatibility with the 1.0 inch arbor hole diameter before installation.

Installation Notes

Installation and insert changes should be performed by a qualified machinist or CNC tooling technician with the spindle fully stopped and machine power isolated per shop lockout/tagout procedures. Inspect the insert pockets and clamping screws for wear or damage before seating new inserts. Torque clamping screws according to the toolholder manufacturer documentation provided with the tool. Confirm coolant port alignment with the machine spindle coolant-through supply before running at full feed rates.
