Sandvik Coromant 5739043 Square-shoulder Face Mill

Product Description

The SANDVIK COROMANT 5739043 is an indexable square-shoulder face mill from the CoroMill 200 series, designed for precision milling operations in metalworking and machining environments. This right-hand cutting tool accepts five RCKT 13 04 00 inserts held by clamp and screw, and features a 0-degree lead angle with negative rake geometry. The cutter body is constructed from steel and measures 2.5 inches in cutting diameter with an overall height of 1.9685 inches (50 mm). It is installed and serviced by machinists and tooling specialists working with CNC milling machines and manual mills requiring face milling capability.

This face mill is suited for close-pitch square-shoulder milling applications in production and job-shop environments. The 1 inch arbor hole diameter allows mounting to standard arbors and milling spindles. With a maximum depth of cut of 0.25 inches and a body diameter of 2.5 inches, it fits applications requiring precise shoulder milling with controlled chip load across five cutting positions. No coolant-through capability is provided, so external coolant delivery should be used when thermal management is required.

Key Features

• Right-hand cutting direction with negative rake geometry for stable cutting performance on steel and similar materials
• Close-pitch insert spacing maximizes the number of cutting edges per pass for the cutter diameter
• Steel cutter body construction for rigidity and dimensional stability during high-feed operations
• Keyway width of 0.3839 inches for positive drive engagement with the arbor

Compatibility

Designed for use with RCKT 13 04 00 series inserts. Compatible with standard 1 inch arbor milling setups. Insert style designation is RA200 within the CoroMill 200 platform.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. The machine spindle must be fully powered down and locked out before mounting or removing the cutter body from the arbor. Inserts should be seated and torqued using the correct insert screw driver per the insert manufacturer's tooling guide — do not overtighten or use impact tools on insert screws. Verify arbor runout after mounting before beginning any cut to confirm proper seating.
