Iscar 3110290 Indexable Chamfer End Mill 30 Degree

Product Description

The ISCAR 3110290 is an indexable chamfer end mill designed for precision milling operations in metal fabrication and machining environments. Built on the IscarMill series platform, this toolholder accepts three TPMT-style inserts secured by screw clamping, providing reliable cutting edge retention during interrupted or continuous cuts. The E30 toolholder style supports a 30-degree lead angle, with a cutting diameter range of 0.625 to 1.61 inches and a maximum depth of cut of 0.27 inches. Overall length measures 3.54 inches. This tool is intended for use by machinists and tooling technicians in production or job-shop settings.

The 3110290 is suited for chamfering, beveling, and milling applications on ferrous and non-ferrous materials where consistent insert indexing is required. The 0.75-inch shank diameter with a Weldon flat provides positive drive and reduces slippage in standard end mill holders. With a functional length of 1.51 inches and a maximum body diameter of 0.75 inches, this tool fits within typical milling machine and machining center setups. It does not include coolant-through capability, making it appropriate for flood or mist coolant delivery from the machine spindle.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Secure the Weldon flat shank firmly in a compatible end mill holder to the torque specification listed by the holder manufacturer before operation. Confirm insert seating and screw torque per ISCAR insert documentation before running the spindle. Always power down and lock out the machine before changing inserts or removing the toolholder from the spindle.
