Sandvik Coromant 8019536 Turning Insert Knux Left Hand Carbide

Product Description

The SANDVIK COROMANT 8019536 is a KNUX-style indexable turning insert designed for metal-cutting lathes and turning centers used in production and job-shop machining environments. This insert is manufactured from solid carbide and features a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, which provides heat resistance and wear protection during steel cutting operations. It carries a left-hand cutting orientation and a 0.0197-inch corner radius, making it suited for specific tool-holder configurations that require left-hand geometry. The manufacturer grade is 4425, positioning it for general steel turning applications where controlled cutting temperatures and edge stability are priorities. Licensed machinists and CNC turning technicians are the primary installers of this insert type.

This insert is intended for use in turning operations on steel workpieces, with a secondary material category code of K, indicating suitability for cast iron as well in appropriate conditions. The KNUX insert style uses a clamp-style holding method, which is standard for negative-rake toolholders designed to accept this insert shape. It is sized to the 1604 insert size code, with a 0.1875-inch thickness and a 0.375-inch width, fitting toolholders designed around that dimensional envelope. Typical applications include external longitudinal turning, facing, and light profiling in a CNC or manual lathe setup where a left-hand insert orientation is required by the toolholder geometry.

Key Features

• CVD multilayer coating: TiCN, Al2O3, and TiN for wear resistance and thermal stability on steel
• Left-hand cutting orientation for compatible left-hand clamp-style toolholders
• 0.0197-inch corner radius suited to general turning with moderate surface finish requirements
• KNUX insert shape code K with clearance code N and tolerance code U
• Chip breaker style 11 integrated into insert geometry
• Clamp-style holding method compatible with KNUX-designated toolholder seats

Compatibility

Designed for use in KNUX-series clamp-style toolholders that accept a left-hand insert with the 1604 size code. The ISO code for this insert is KNUX 16 04 05L11 4425. Specific toolholder compatibility should be verified against the toolholder manufacturer's insert specification chart before installation.

Installation Notes

Insert installation and indexing should be performed by a qualified machinist or CNC tooling technician with the machine in a fully stopped and locked-out state per applicable machine safety procedures. Use the correct clamp screw torque as specified by the toolholder manufacturer's documentation, as under- or over-tightening the clamping mechanism can cause insert movement or premature failure. Inspect the toolholder seat and clamping components for wear or debris before seating the new insert. Handle carbide inserts carefully to avoid edge chipping prior to use.
