Seco 02506645 WCMX0686 T400D Carbide Indexable Drill Insert

Product Description

The SECO 02506645 is a WCMX-style indexable drill insert engineered for use in indexable insert drills across a wide range of workpiece materials. It is manufactured from solid carbide with a PVD coating applied under the T400D manufacturer grade designation. The insert features an 80-degree trigon shape with a 7-degree relief angle and a 0.80 mm corner radius. These characteristics support controlled chip formation and consistent edge performance during drilling operations. Installation is performed by licensed machinists and CNC operators in production and job-shop environments.

This insert is rated for universal application, covering material groups H, K, M, N, P, and S. That range includes cast iron, non-ferrous metals, stainless and heat-resistant alloys, general steels, and non-metals. It is suited for wet or dry drilling applications where a trigon-geometry insert is specified. The WCMX insert style is compatible with tool holders designed for WCMX seating geometry. Insert size code is 06, corresponding to insert size designation 06T308.

Key Features

• Solid carbide substrate with PVD coating under T400D grade for wear resistance across diverse materials
• 80-degree trigon (WCMX) shape with 7-degree relief angle for positive cutting action
• 0.80 mm corner radius balances edge strength and surface finish
• Chipbreaker style 86 promotes efficient chip evacuation in through-hole and blind-hole drilling
• Universal material compatibility covering ISO groups H, K, M, N, P, and S
• Insert size code 06 (06T308) fits WCMX-configured drill bodies

Compatibility

Designed for use in indexable insert drill bodies that accept WCMX seating geometry, insert size code 06 (06T308). Compatible workpiece material groups include H, K, M, N, P, and S per supplier data. Confirm tool holder seating geometry and pocket dimensions before installation.

Installation Notes

Installation and indexing should be performed by a qualified machinist or tooling technician. Ensure the drill body and insert pocket are free of chips and debris before seating the insert. Use the correct torx or hex key specified by the drill body manufacturer to achieve proper clamping torque. Do not exceed the cutting parameter ranges specified in the tool holder documentation for the selected material group.
