Walter 6381793 Indexable Drill Insert WOEX12E57 WKP35S

Product Description

The WALTER 6381793 is a carbide indexable drill insert designed for high-performance hole-making in demanding metalworking applications. Carrying the insert style designation WOEX and grade WKP35S from the Tiger-tec Silver series, it features a CVD coating system consisting of TiCN, Al2O3, and TiN layers for extended tool life and thermal resistance. The trigon shape provides three usable cutting edges per insert. The chipbreaker geometry is E57, suited to controlled chip formation in drilling operations. This insert is installed and replaced by machinists and tool-room technicians working with indexable drill bodies.

This insert is rated for primary workpiece materials of cast iron and steel, corresponding to ISO material codes K and P, and carries an ISO grade of P35 and K35. It is appropriate for use in production drilling environments, both manual and CNC-controlled, where indexable insert drills are the preferred tooling strategy. The ISO code for this insert is WOEX120608-E57 WKP35S, and it conforms to both ANSI and ISO standards.

Compatibility

Designed for use with indexable drill bodies accepting WOEX-style inserts in insert size 12 (ISO size code 120608). Compatible with primary workpiece materials cast iron and steel. Verify seating pocket dimensions and clamping method against the drill body manufacturer specifications before installation.

Installation Notes

Indexable insert replacement is performed by qualified machinists or toolroom technicians. Power down and lock out the machine spindle before removing or seating inserts. Use the appropriate torx or hex key as specified by the drill body manufacturer to achieve proper clamp torque; do not overtighten or substitute fasteners. Inspect the insert pocket and clamping screw for wear or debris before seating a new insert.
