Kyocera 8858935 Indexable Drill Insert Wcmx CA6535

Product Description

The KYOCERA 8858935 is a solid carbide indexable drill insert in the WCMX insert style, designed for use with compatible indexable drill bodies in metal cutting and machining operations. This insert carries the manufacturer grade CA6535 and features a multilayer CVD coating of TiCN, Al2O3, and TiN, which provides wear resistance and thermal protection during cutting. The chipbreaker designation is M1, suited for moderate cutting conditions. With an 80-degree included angle and a 0.80 mm corner radius, this insert is engineered for precision hole-making in a variety of workpiece materials. Licensed machinists and CNC operators are the primary installers.

This insert is intended for use with OTMD-style compatible indexable drill bodies. The primary workpiece material designation is M, indicating suitability for stainless steels and other difficult-to-machine alloys per ISO classification. It is sold individually and is appropriate for production environments requiring repeatable, consistent cutting performance in drilling operations. The right-hand cutting direction makes it a standard orientation for conventional CNC drilling setups.
