Kennametal 1023678 Indexable Chamfer End Mill

Product Description

The KENNAMETAL 1023678 is a 45-degree lead angle indexable chamfer end mill designed for chamfering and countersinking operations on machined components. It accepts two SDEB 26152 style inserts held by screw clamp, giving the tool predictable insert indexing and consistent edge geometry. The cutting diameter ranges from 1.2 inches to 1.66 inches with a maximum depth of cut of 0.195 inches. Overall length is 3.25 inches. The Weldon flat shank interfaces with standard KIPR toolholders for secure radial drive in milling spindles. Maximum spindle speed is 9,750 RPM. This tool is used by machinists and CNC mill operators working in job shop and production environments.

This chamfer end mill is suited for chamfering bores, deburring edges, and producing angled entry features on ferrous and non-ferrous workpieces. The 45-degree lead angle is a common geometry for edge preparation before assembly or threading operations. With a 1.2-inch minimum cutting diameter and a 1.22-inch head length, it fits tooling setups where clearance and reach are defined by the fixture. The two-insert design keeps tool weight and cutting forces moderate, making it appropriate for both knee mills and CNC machining centers. Coolant-through capability is not available on this holder style.

Installation Notes

Installation and tool changes should be performed by qualified machinists or CNC setup personnel with the spindle at a full stop and machine power isolated. Secure the Weldon flat shank in the KIPR toolholder to the torque specification listed in the toolholder manufacturer documentation. Verify insert seating and screw clamp torque before initiating a cut. Follow applicable shop safety standards and machine manufacturer guidelines when setting tool offsets and spindle speeds.
