Sandvik Coromant 5782733 Square Ceramic Milling Insert

Product Description

The SANDVIK COROMANT 5782733 is a square, double-sided ceramic milling insert in grade 6190, made from uncoated silicon nitride. It belongs to the N365 series and carries ANSI and ISO designation N365-1505ZNE 6190. The insert features a negative rake angle, a flat-top chip breaker, and eight usable cutting edges, making it an efficient choice for high-productivity face and shoulder milling operations. With an inscribed circle of 0.5906 inches (15.00 mm) and a thickness of 0.2228 inches (5.66 mm), this insert is sized for robust material removal in demanding applications. It is held in place by a screw-type clamping method.

This insert is designed for milling cast iron and hard materials, applications where silicon nitride ceramic grade 6190 performs reliably at elevated cutting speeds. It suits both roughing and semi-finishing passes in those material categories. The neutral hand orientation means it works in a range of cutter body orientations. Licensed HVAC techs are not the audience here — this insert is specified and installed by machinists, CNC operators, and tooling engineers in job shops, production floors, and maintenance machining environments. Compatible cutter series listed in the input include the L365 and R365 cutter bodies.

Key Features

• Silicon nitride ceramic grade 6190 — bright, uncoated finish for cast iron and hard material applications
• Eight cutting edges on a double-sided, square insert body — reduces cost per edge
• Negative rake, flat-top chip breaker geometry with corner-rounded cutting edge style
• Maximum depth of cut of 6.00 mm (0.2362 inches)
• Corner radius of 3.60 mm (0.1417 inches) for controlled edge engagement
• Screw-held insert seating for positive, repeatable location in the cutter pocket
• Meets ANSI and ISO standards under code N365-1505ZNE 6190

Compatibility

Compatible with the L365 and R365 cutter series. ANSI and ISO designation N365-1505ZNE 6190. Insert size code 1505. Verify pocket geometry and seat condition in the cutter body before installation.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Power down and lock out the machine spindle before seating or removing inserts. Use the correct Torx or hex key for the clamping screw and follow the cutter body manufacturer's fastener procedure — do not overtighten or undertighten the screw. Inspect the insert pocket and seating surface for chips or debris before placing the insert, as ceramic inserts are sensitive to uneven seating forces.
