Sandvik Coromant 5742708 R210 Milling Insert Solid Carbide

Product Description

The SANDVIK COROMANT 5742708 is a solid carbide milling insert designed for use in R210-series face and shoulder milling cutters. It carries a CVD-applied multilayer coating of TiCrN, Al2O3, and TiN classified under manufacturer grade 2040, which targets wear resistance and heat dissipation in demanding cutting operations. The insert features a square shape with a positive rake angle, a 1.00 mm corner radius, and four cutting edges per insert, making it a cost-efficient option for high-volume metal removal. At 0.1875 inches thick with an inscribed circle of 0.5709 inches, it matches the R210-14 05 12M-MM toolholder specification. This insert is installed by machinists and CNC tool setup technicians working in production and job-shop environments.

The 5742708 is rated for primary workpiece materials including steel (P45), stainless steel (M40), and superalloys and titanium (S30). It is suited for roughing and semi-finishing operations where controlled chip formation is required. The MM chip breaker geometry supports moderate feed rates and stable cutting across these material groups. Maximum depth of cut is 2.00 mm (0.0787 inches). The insert is right-hand cutting and uses a screw-clamp holding method compatible with R210-series cutter bodies. Insert size code is 140512 and the full ANSI and ISO designation is R210-14 05 12M-MM 2040.

Key Features

• CVD multilayer coating: TiCrN, Al2O3, TiN for thermal and abrasion resistance in grade 2040
• Square insert shape with 90-degree included angle and 1.00 mm corner radius for shoulder milling applications
• Four usable cutting edges per single-sided insert maximizes cost-per-edge value
• Positive rake geometry reduces cutting forces on stainless steel, superalloys, and titanium
• MM chip breaker designed for moderate feeds and reliable chip control across P, M, and S material groups
• Compliant with ANSI and ISO standards; full code R210-14 05 12M-MM 2040

Compatibility

Designed for use with Sandvik Coromant R210-series milling cutter bodies. Insert size code 140512 corresponds to the R210-14 05 12M-MM toolholder designation. Compatible cutter series: R210.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Always index or replace inserts with the machine powered off and the spindle fully stopped. Use the appropriate Torx or hex key at the manufacturer-specified seating torque for the cutter body — refer to the cutter body documentation for that value, as it is not insert-specific. Inspect the insert pocket and seating surfaces for chips or debris before seating a new insert to ensure full contact and accurate runout.
