Walter 5004946 SEHW1204AFN Wkm Milling Insert Solid Carbide

Product Description

The WALTER 5004946 is a solid carbide milling insert designed for precision material removal in demanding machining operations. Carrying the ANSI and ISO designation SEHW1204AFN WKM, this insert features a square shape with a 90-degree included angle, a positive rake geometry, and a honed cutting edge style. The flat-top chip breaker promotes efficient chip evacuation across a wide range of cutting conditions. With 4 usable cutting edges per insert and a neutral hand orientation, it delivers consistent performance in high-volume milling applications where tooling economy matters.

This insert is engineered primarily for cast iron and non-ferrous metal workpiece materials, making it a practical choice for manufacturing, job shop, and production milling environments. The WKM grade targets applications where sharp, uncoated carbide edges outperform coated alternatives, particularly in aluminum alloys, copper alloys, and gray or ductile cast iron. It seats via screw clamping and is suited for face milling, shoulder milling, and similar operations where insert indexability and repeatability are critical.

Key Features

• Square insert shape with 90-degree included angle and positive rake for low cutting forces
• 4 cutting edges per insert for extended tooling economy
• Honed cutting edge style with flat-top chip breaker for controlled chip flow
• Uncoated solid carbide construction in WKM grade, optimized for cast iron and non-ferrous metals
• Neutral hand orientation for flexible use in a range of cutter bodies
• Screw-clamp holding method ensures secure, repeatable insert seating

Compatibility

Designed as an OEM-style replacement or direct-fit insert for milling cutter bodies that accept the SEHW1204 insert size with screw-clamp retention. Conforms to ANSI and ISO standards for SEHW series inserts.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician with the spindle fully stopped and machine power isolated before any insert change. Use the appropriate Torx or hex key to seat the clamping screw to the cutter body manufacturer's specified torque range. Inspect the insert pocket and seating surfaces for chips or debris before indexing to a fresh cutting edge. Do not use damaged or chipped inserts, as insert failure at speed presents a serious safety hazard.
