Kennametal 1023677 Indexable Chamfer End Mill

Product Description

The KENNAMETAL 1023677 is an indexable chamfer end mill designed for precision chamfering and beveling operations on metalworking machining centers and CNC mills. Built around a 45-degree lead angle, it accepts two SDEB 26152 style inserts secured by screw clamping and mounts via a KIPR Weldon Flat shank toolholder. The cutting diameter range spans 0.95 inches minimum to 1.387 inches maximum, with a maximum depth of cut of 0.195 inches. Overall assembly length is 3.25 inches. The tool supports spindle speeds up to 10,000 RPM and does not incorporate coolant-through capability. Machinists and tool-and-die professionals install this type of tooling to produce consistent chamfers on bored holes, shaft ends, and mating surfaces across production and job-shop environments.

This chamfer end mill is suited for use in ferrous and non-ferrous metal machining applications where a controlled 45-degree chamfer or countersink profile is required. The indexable insert design allows worn cutting edges to be rotated or replaced at the machine without removing the toolholder body, reducing downtime in high-cycle production runs. The Weldon Flat shank provides a positive anti-pullout seating in standard milling chucks and side-lock holders. Typical applications include chamfering bolt-hole patterns, deburring bored features, and preparing mating faces for assembly in precision fabrication and manufacturing settings.

Compatibility

Designed for use with KIPR-style Weldon Flat toolholders and SDEB 26152 indexable inserts. Compatible with CNC machining centers and milling machines equipped with side-lock or Weldon Flat chuck systems accepting the corresponding shank diameter. No additional model-specific compatibility data was provided by the manufacturer for this listing.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician familiar with indexable milling toolholders. Confirm the machine spindle is fully stopped and locked out before mounting or changing inserts. Secure the Weldon Flat shank firmly in the side-lock holder using the appropriate hex key to the holder manufacturer torque specification. Inspect inserts for seating and screw engagement before initiating any cutting pass.
