Iscar 3101948 Indexable Square-shoulder End Mill

Product Description

The ISCAR 3101948 is an indexable square-shoulder end mill from the Heli2000 series, designed for precision milling operations in metalworking and machining environments. This HM90 E90A-10 toolholder features a 0.75-inch cutting diameter, a 90-degree lead angle, and a maximum depth of cut of 0.394 inches. Built from solid carbide with a Weldon flat shank, it accepts AP..1003.. series inserts secured by screw clamping. With a 3.38-inch overall length and a 2-flute configuration, it is suited for demanding square-shoulder milling applications requiring tight tolerances and consistent chip evacuation. Installation and use are handled by machinist and toolroom professionals.

This end mill is used in production machining and toolroom environments where square-shoulder profiles and precise radial engagement are required. The Heli2000 series is engineered for high-feed milling on steel, stainless, cast iron, and similar materials. The 0.75-inch Weldon flat shank provides secure seating in compatible tool holders, reducing pull-out risk during interrupted cuts or high-feed passes. The 90-degree lead angle promotes clean shoulder formation and minimizes axial forces on the spindle. No coolant-through capability is present on this toolholder.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Ensure the machine spindle is fully powered down and locked out before mounting or changing inserts. Secure the Weldon flat shank in the tool holder to the appropriate interface specification using a side-lock set screw. Follow the insert manufacturer torque guidance for screw-clamped inserts when seating AP..1003.. style inserts to avoid over-torquing the clamping screw.
