Iscar 3105272 Indexable Square-shoulder End Mill

Product Description

The ISCAR 3105272 is an indexable square-shoulder end mill designed for precision milling operations in metal fabrication and machining environments. Built on the Helido series platform, this tool features a 90-degree lead angle and helical flute geometry that supports efficient chip evacuation and consistent surface finish on square-shoulder cuts. The cutter accepts four indexable inserts held by screw-mount retention and is manufactured from solid carbide. Through-coolant capability allows coolant delivery directly to the cutting zone, reducing heat buildup during extended cuts. Licensed machinists and CNC operators working in aerospace, general manufacturing, and job-shop environments are the primary users of this tool.

This end mill is suited for square-shoulder milling applications where a true 90-degree wall angle is required. The Helido series geometry supports ramping, helical interpolation, and face milling operations on ferrous and non-ferrous workpieces. The Weldon flat shank provides positive drive engagement in standard end mill holders, making this tool compatible with vertical machining centers and horizontal mills equipped with appropriate toolholding. Through-coolant is particularly useful in deep-cavity or high-feed applications where flood coolant cannot reach the insert.

Key Features

• 90-degree lead angle for true square-shoulder milling
• Helical flute design promotes efficient chip flow and reduced cutting forces
• Through-coolant construction for direct coolant delivery to the cutting edge
• Four-insert configuration for balanced cutting and higher metal removal rates
• Weldon flat shank for positive, slip-resistant toolholder engagement
• Manufactured to AS 9100, ISO 9001:2008, ISO 14001:2004, ISO 50001, and OHSAS 18001:2007 standards

Compatibility

Designed as an OEM Helido series indexable end mill compatible with ISCAR H490 cutter-style insert grades. Consult the ISCAR Helido insert selection guide to confirm insert grade and geometry for your specific workpiece material.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and locked out before mounting or removing the tool. Seat the Weldon flat shank fully into the toolholder and tighten the set screw against the flat to the toolholder manufacturer specification. Verify insert seating and screw torque per the ISCAR insert installation guidelines before beginning any cut.
