Iscar 3101764 Indexable Square-shoulder End Mill

Product Description

The ISCAR 3101764 is an indexable square-shoulder end mill from the Heli2000 series, designed for precision milling operations in metalworking and machining environments. Built around the HM90 E90AD-15 toolholder platform, this cutter features a 1-inch cutting diameter, a 90-degree lead angle, and a maximum depth of cut of 0.56 inches. It accommodates two helical flutes and accepts AD..1505.. and HM90 AD..1505 insert styles, secured by screw clamping. Through-coolant capability supports higher cutting speeds and extends insert life in demanding applications. Installed by machinists and tooling specialists, this end mill suits CNC machining centers in production and job-shop environments.

This end mill is suited for square-shoulder milling operations on ferrous and non-ferrous materials where tight 90-degree wall angles are required. The Weldon flat shank with a 1-inch shank diameter and 2.5-inch shank length provides secure tool holding in standard Weldon-style chucks and end mill holders. The 4-inch overall length and 1.47-inch usable length make it appropriate for moderate-depth shoulder and slot milling passes. Maximum ramping angle is 11.5 degrees, supporting helical and ramp entry strategies on compatible CNC machines.

Key Features

• 1-inch cutting diameter with 90-degree lead angle for true square-shoulder profiles
• 0.56-inch maximum depth of cut per pass
• Through-coolant design for improved chip evacuation and thermal management
• 2-flute helical configuration for balanced cutting forces
• Weldon flat shank for positive, slip-resistant tool holding
• Compatible with a broad family of AD..1505.. insert styles including ADCT, ADCR, ADKR, ADKT, ADMT, and HM90 variants

Compatibility

Compatible insert styles include ADCT, ADCR, ADKR, ADKT, ADMT, HM90ADCT, HM90ADKT, and HM90ADKW 1505 in the 1505 size class. Insert compatibility references: AD..1505.. and HM90 AD..1505. Toolholder series designation is HM90 E90AD-D1.0-2-W1.0-C.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Secure the Weldon flat shank fully into the tool holder and torque the set screw against the flat to prevent axial pullout. Verify coolant through-spindle pressure and flow before beginning cuts to ensure proper chip evacuation. Inspect insert seating and screw torque before each use and follow the machine tool manufacturer guidelines for spindle speed and feed rate for the insert grade selected.
