Sandvik Coromant 8021011 Turning Insert Carbide Knmx

Product Description

The SANDVIK COROMANT 8021011 is a CVD-coated carbide turning insert engineered for demanding metal cutting applications. Catalogued under the ISO designation KNMX 16 04 05 R-71 4415, this insert features a multilayer TiCN, Al2O3, and TiN coating applied by chemical vapor deposition for wear resistance and thermal stability. The K-shape insert geometry combined with an N clearance angle and M tolerance class delivers consistent dimensional accuracy across production runs. With a 0.0197 inch corner radius and PR chip breaker, it is suited for finishing to medium roughing operations. Machinists and CNC tool-crib technicians working in job shops or production environments select this insert for reliable tool life on ferrous and non-ferrous workpiece materials.

This insert is intended for use in right-hand turning operations on CNC lathes and turning centers. The KNMX insert style is held by a clamp-style toolholder, making it a standard fit across a wide range of compatible toolholder systems. The secondary workpiece material code K indicates suitability for cast iron and hardened materials alongside its primary application range. It is most commonly specified in high-volume turning setups where consistent chip control and coating durability are required across extended production cycles.

Key Features

• CVD multilayer coating: TiCN, Al2O3, and TiN for high wear resistance and thermal barrier performance
• K-shape insert geometry with 0.0197 inch corner radius for controlled surface finish
• PR chip breaker geometry for effective chip control across a range of depths of cut
• Carbide substrate grade 4415 suited for stable cutting conditions
• Clamp-style holding method compatible with standard KNMX toolholders
• M tolerance class ensures repeatable insert positioning and dimensional consistency

Compatibility

Designed as a direct-fit replacement for applications specifying ISO code KNMX 16 04 05 R-71 4415 in clamp-style right-hand turning toolholders.

Installation Notes

Insert replacement should be performed by a qualified machinist or tool-crib technician with the machine in a stopped, locked-out state per applicable machine safety procedures. Use the appropriate torque wrench and clamp hardware specified by the toolholder manufacturer when seating the insert. Inspect the insert pocket for wear or debris before installation to ensure proper seating. Do not exceed the cutting parameter ranges published in the manufacturer tooling catalog for this grade and geometry combination.
