Iscar 3103894 Indexable Square-shoulder End Mill

Product Description

The ISCAR 3103894 is a 2-flute indexable square-shoulder end mill from the Heliplus series, designed for precision milling operations in metal-cutting applications. It features a 0.5-inch cutting diameter, a maximum depth of cut of 0.303 inches, and a 90-degree lead angle that promotes true square shoulders in workpieces. The Weldon flat shank measures 0.5 inches in diameter and 2.5 inches in length, providing secure tool holding in compatible chucks. Inserts are retained by screw-lock, using the HP AN.. 0702.. insert style. This tool is installed and set up by machinists and CNC operators working in production or job-shop environments.

The ISCAR 3103894 suits general milling tasks where square-shoulder profiles and reliable insert indexing are required. The Heliplus cutter style HP E90AN-07 with a 90-degree lead angle is well suited for slotting, side milling, and shoulder milling on ferrous and non-ferrous materials. The 3.25-inch overall length and compact 0.75-inch head length make it appropriate for use in both vertical machining centers and manual mills where clearance is a consideration. Coolant-through capability is not included in this toolholder design.

Compatibility

Designed for use with HP AN.. 0702.. series indexable inserts. Cutter style is HP E90AN-07, part of the ISCAR Heliplus series. Manufacturer catalog number HP E90AN-D.50-2-W.50-7 can be used for cross-reference when sourcing compatible inserts or verifying fitment in existing tooling programs.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. Secure the Weldon flat shank in a compatible end mill holder or Weldon-style chuck, ensuring the set screw engages the flat to prevent axial pull-out. Power down and lock out the spindle before changing inserts or mounting the tool. Follow shop-specific tooling procedures and verify runout with a dial indicator before production cuts.
