Kennametal 1024578 Indexable Chamfer End Mill

Product Description

The KENNAMETAL 1024578 is an indexable chamfer end mill designed for chamfering and edge-prep operations on machined components. It accepts one SD.. 0903.. style insert secured by a screw-clamp holding method, making insert changes fast and repeatable. The 45-degree lead angle suits standard chamfer work across a cutting diameter range of 0.3937 inches to 0.8661 inches. Overall length is 3.256 inches with a 0.6299-inch Weldon Flat shank for positive drive and minimal runout at speeds up to 33,780 RPM. Machinists and tooling technicians working in production or job-shop environments will find this tool well-suited to high-throughput chamfering cycles.

This end mill is intended for metalworking applications where consistent chamfer geometry and repeatable edge quality are required. It is a single-flute indexable design, making it appropriate for applications where cutting forces need to remain manageable. Maximum depth of cut is 6.5 mm, which positions this tool for chamfering and lead-in work rather than full-profile milling. The Weldon Flat shank is compatible with standard end mill holders equipped to accept that shank style. Coolant-through is not supported on this tool, so external coolant or air blast should be planned accordingly.

Installation Notes

Installation and insert changes should be performed by a qualified machinist or tooling technician with the machine in a full stop and lockout/tagout procedures in place. Seat the Weldon Flat shank fully into the holder and torque the set screw per the holder manufacturer specification before running. Inspect the insert seat and clamping screw for wear or debris before each insert change. Verify spindle speed does not exceed the 33,780 RPM maximum rating for this tool.
