Walter 7487733 Indexable Drill Insert Square WK40 Carbide

Product Description

The WALTER 7487733 is a solid carbide indexable drill insert designed for use in indexable insert drills in demanding metal-cutting applications. Built to insert style P284 and graded WK40, this square-shaped insert features a 96-degree included angle and four cutting edges, maximizing the number of usable edges per insert before replacement. At 0.3800 inches in both width and length, it conforms to ANSI and ISO standards and carries ISO code P2840S-3N-E67 WK40. Licensed machinists, tool-and-die technicians, and CNC operators working in high-mix production environments are the primary installers and end users.

This insert is engineered for primary application in non-ferrous metals, superalloys, and titanium, making it well-suited for aerospace, medical device, and precision-machined-component manufacturing. The WK40 carbide grade is selected for its balance of wear resistance and toughness in these challenging workpiece categories. It is sized to insert size code 28 and fits drilling tool bodies designed to accept P284-style square inserts. Both ANSI and ISO conformance broadens its compatibility across globally sourced tooling systems.

Key Features

• Solid carbide construction in manufacturer grade WK40 for wear resistance in superalloy and titanium cutting
• Square shape with 96-degree included angle and four cutting edges per insert
• Width and length of 0.3800 inches for precision fit in size code 28 tool bodies
• Primary workpiece material codes N and S cover non-ferrous metals, superalloys, and titanium
• Dual ANSI and ISO compliance for broad tooling system compatibility
• ISO code P2840S-3N-E67 WK40 for exact cross-reference and procurement matching

Compatibility

Designed for indexable insert drill bodies that accept P284-style square inserts at insert size code 28, conforming to ANSI and ISO standards. Verify tool body seat geometry and ISO code P2840S-3N-E67 WK40 against your specific drill body documentation before ordering.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and the tool is secured in a vise or tool holder before seating or removing inserts. Use the correct torx or hex key at the manufacturer-specified procedure for the tool body clamp screw - do not overtighten, as carbide inserts are brittle and can crack under excessive clamping force. Inspect the insert pocket seat for debris or damage before seating a new insert.
