Sandvik Coromant 5741277 Round Turning Insert 1/2 in Ic

Product Description

The SANDVIK COROMANT 5741277 is a solid carbide, uncoated turning insert designed for precision metal cutting operations on CNC lathes and turning centers. Featuring a round insert shape (Shape Code R) with a 1/2 inch inscribed circle and 5/16 inch insert thickness, this insert carries ISO Code RNGN120700E in grade 6060. The clearance code is N (zero-degree relief angle) and the tolerance code is G, indicating a ground insert held by a clamp-style toolholder. Grade 6060 is an uncoated carbide grade suited for applications where a bright, uncoated cutting edge is required. Machinists and CNC operators install this insert into compatible round-pocket toolholders as part of a precision external or internal turning setup.

This insert is suited for turning operations in machining environments where consistent edge geometry and dimensional accuracy are critical. The round shape distributes cutting forces evenly across the edge, making it appropriate for both roughing and finishing passes depending on feed rate and depth of cut selections. The RNGN insert style is commonly used on production turning equipment in job shops, aerospace, and general-purpose machining facilities. Install size code 45 corresponds to the 12.70 mm inscribed circle class.

Key Features

• Round insert shape (Code R) with 1/2 inch (12.70 mm) inscribed circle for full 360-degree usable edge
• Solid carbide substrate, grade 6060, bright/uncoated finish
• Insert thickness of 5/16 inch (7.94 mm) for stable seating in clamp-style toolholders
• Zero-degree relief angle (Clearance Code N) with G tolerance for ground precision fit
• No chip breaker geometry — flat top for unrestricted chip flow in specialty applications
• ISO designation RNGN120700E 6060 for direct cross-reference to compatible toolholder systems

Compatibility

Designed for use in clamp-style round-insert toolholders accepting RNGN-style inserts with a 1/2 inch inscribed circle and insert size code 45. Verify toolholder pocket specifications against ISO Code RNGN120700E before installation.

Installation Notes

Turning inserts are installed and replaced by machinists and CNC tooling technicians. Always bring the machine spindle to a full stop and engage the E-stop before indexing or replacing an insert. Use the manufacturer-specified torque for the clamping screw — refer to the toolholder documentation for the correct value, as this insert data does not include a torque specification. Inspect the toolholder pocket for wear, debris, or damage before seating the new insert, as a compromised pocket will affect edge accuracy and tool life.
