Iscar 3105547 High-feed End Mill 1-1/4 in 4 Flute

Product Description

The ISCAR 3105547 is an indexable high-feed end mill designed for aggressive milling operations where high material removal rates are the priority. Built around the High Feed 6 series platform, it accepts 4 H600WXCU05T312T inserts secured by screw clamping. The cutting diameter measures 1.25 inches, with a maximum depth of cut of 0.04 inches per pass — a geometry optimized for high-feed, low-depth chip thinning strategies. Overall length is 4.95 inches. A 1-inch Weldon Flat shank provides positive drive and resists pullout under heavy cutting loads. Through-coolant capability directs fluid directly to the cutting zone for improved chip evacuation and insert life.

This end mill is suited for face milling, shoulder milling, and ramping applications in production machining environments. The maximum ramping angle is 4 degrees. With a minimum cutting diameter of 0.86 inches and a maximum of 1.25 inches, the FF EWX-05 toolholder-style body is at home on CNC machining centers handling steel, cast iron, and other ferrous workpieces in both roughing and semi-finishing operations. The 4-flute configuration balances feed rate capability with chip room. Machinists and tooling specialists working in job shops or high-volume production cells will find this a straightforward drop-in for high-feed programs.

Key Features

• 1.25-inch cutting diameter with 0.04-inch maximum depth of cut for high-feed chip thinning
• 4 H600WXCU05T312T indexable inserts, screw-clamped for repeatable seating
• Through-coolant design for direct flood cooling at the cutting edge
• 1-inch Weldon Flat shank for positive anti-pullout drive in standard milling chucks
• Maximum ramping angle of 4 degrees for helical or linear ramp entry
• Compliant with ISO 13399 tooling data standards for CAM system integration

Compatibility

Compatible with H600WXCU05T312T inserts. Toolholder style is FF EWX-05. Catalog reference number is FF EWXD1.25-4-2.5W1.00-05. Confirm spindle interface and collet or chuck bore matches the 1-inch Weldon Flat shank diameter before ordering.

Installation Notes

Installation is performed by a machinist or tooling technician. Power down and lock out the machine spindle before changing tooling. Seat the Weldon Flat shank fully into the chuck and torque the drive screw to the machine manufacturer's specification. Inspect insert pockets and seating surfaces for chips or debris before indexing or replacing inserts, and verify insert orientation matches the pocket geometry called out in the ISCAR tooling documentation.
