Sandvik Coromant 5740105 Square-shoulder Face Mill

Product Description

The SANDVIK COROMANT 5740105 is an indexable square-shoulder face mill designed for precision milling operations in metal cutting applications. Built on the CoroMill 390 platform, it accepts six R390-11.. style inserts secured by clamp and screw, delivering a 90-degree lead angle with a positive rake geometry. The cutter body is constructed from steel, measures 1.5750 inches in overall height, and has a maximum cutting diameter of 1.5 inches (38.10 mm). A 0.75-inch arbor hole provides secure mounting to compatible toolholders. Licensed machinists and CNC operators use this tool for right-hand cutting passes on vertical and horizontal machining centers where shoulder milling and face milling operations are required.

This face mill is suited for coarse-pitch roughing and semi-finishing passes in shop environments running horizontal or vertical machining centers. Its compact 1.5-inch cutting diameter makes it appropriate for smaller workpieces or tight-clearance shoulder milling where a full-size cutter would not fit. The CoroMill 390 series is a widely used platform in production shops and job shops running steel, stainless, and cast iron. The six-insert configuration maximizes metal removal rate at this cutter diameter. Installation is handled by qualified machinists or CNC tooling specialists.

• 90-degree lead angle delivers true square shoulders in a single pass
• Accepts 6 inserts in R390-11.. style for high metal removal rates
• Positive rake geometry reduces cutting forces and heat generation
• Right-hand cutting direction with coarse pitch insert spacing
• Steel cutter body with clamp and screw insert retention for rigid, repeatable indexing

Compatibility

Designed for use with R390-11.. compatible inserts on the CoroMill 390 series platform. Mounts on toolholders with a 0.75-inch arbor hole. Refer to SANDVIK COROMANT toolholder selection guides for compatible arbor and adapter configurations.

Installation Notes

Installation and tool changes should be performed by a qualified machinist following standard machine tool lockout and energy-isolation procedures before handling the cutter body or indexing inserts. Use calibrated torque tools when seating insert clamp screws to the cutter body per the insert manufacturer specifications available in the tooling documentation. Verify arbor fit and runout with a dial indicator before initiating a cutting pass. Follow applicable shop safety standards and machine manufacturer guidelines for cutter mounting and maximum RPM.
