Sandvik Coromant 5740046 Square-shoulder Face Mill 4 in

Product Description

The SANDVIK COROMANT 5740046 is an indexable square-shoulder face mill designed for high-productivity milling operations in metalworking and machining applications. Built around the CoroMill 245 platform, this cutter accepts 10 R245-12T3 style inserts and delivers a maximum cutting diameter of 4 inches (101.60 mm) with a maximum depth of cut of 0.24 inches (6.10 mm). The 1-1/2 inch arbor hole diameter and coarse pitch configuration make this mill a reliable choice for machinists and tooling specialists running horizontal or vertical milling machines in production environments.

This face mill is suited for square-shoulder milling of steel and similar workpiece materials in job shop and production machining environments. The 45-degree lead angle with a positive rake geometry promotes efficient chip formation and reduced cutting forces. At 50 mm overall height and 4 inches body diameter, the cutter fits standard arbor setups on knee mills and machining centers. Tooling engineers and CNC machinists typically specify this cutter for face milling, shoulder milling, and step milling operations where consistent insert indexing and repeatable depth control are required.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully powered down and locked out before mounting or removing the cutter. Confirm arbor diameter and keyway dimensions match the host spindle before assembly. Torque all clamping screws to the toolholder manufacturer's specification found in the CoroMill 245 documentation; do not substitute values.
