Sandvik Coromant 8019519 Rcmt 09 T3 00 Turning Insert

Product Description

The SANDVIK COROMANT 8019519 is a round carbide turning insert in the RCMT (INCH) series, designed for single-point turning operations on CNC lathes and turning centers. It carries manufacturer grade 4425 with a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, delivering wear resistance and thermal protection during continuous and semi-interrupted cuts. The insert has a neutral hand orientation, a 0.1875-inch corner radius, and a round shape (insert shape code R), making it suited for profiling, facing, and contouring passes. A licensed machinist or CNC operator installs this insert into compatible RCMT-style toolholders using a clamp or screw holding method.

This insert is rated primarily for steel cutting applications and carries a secondary workpiece material code of K, indicating suitability for cast iron as well. It fits standard RCMT insert pockets with clearance code C and tolerance code M per ISO designation RCMT 09 T3 00 4425. Typical use is in production turning environments where consistent tool life and surface finish repeatability are required across medium to high material removal rate operations.

Key Features

• Round insert shape (code R) supports profiling, contouring, and high-feed radial passes
• CVD multilayer coating: TiCN base, Al2O3 thermal barrier, TiN top layer for wear indication
• Manufacturer grade 4425 optimized for steel as primary workpiece material
• Neutral hand orientation fits left-hand, right-hand, and straight toolholders
• Clamp and screw holding method provides rigid seating in RCMT-style pockets
• ISO designation RCMT 09 T3 00 4425 with chip breaker code 00 for open-geometry cutting

Compatibility

Designed for use in RCMT-style toolholders and insert pockets conforming to the RCMT (INCH) series standard, with clearance code C and tolerance code M. Specific toolholder compatibility should be confirmed against the RCMT 09 T3 insert size code and the toolholder manufacturer's pocket specification.

Installation Notes

Installation is performed by a qualified CNC machinist or toolroom technician. Power down and lock out the machine spindle before seating or replacing inserts. Seat the insert fully and evenly in the pocket before tightening the clamp or screw to the toolholder manufacturer's specified procedure. Inspect the insert pocket for chips, debris, or wear before each insert change to prevent premature edge failure or poor surface finish.
