Kennametal 1288264 Slotting Cutter Adapter Straight Shank

Product Description

The KENNAMETAL 1288264 is a straight-shank slotting cutter adapter designed to mount slotting cutters on milling machines and machining centers. It accepts cutters with a 1-inch hole diameter and features a 1.25-inch straight shank for secure tool holding. The adapter measures 3.968 inches in overall length and provides a 0.75-inch projection. Weighing approximately 1.7 pounds, this adapter is built for precision slotting operations in production and job-shop environments. It is installed by machinists and CNC setup technicians working with horizontal or vertical milling setups requiring slotting cutter assemblies.

This adapter is suited for slotting operations in metalworking applications where a straight-shank connection is required. It is compatible with slotting cutters that have a 1-inch arbor hole diameter. The included hardware — a 0.156-inch spacer, drive key, and lock screw — allows for complete assembly without sourcing additional components. Typical applications include keyway cutting, groove milling, and slot machining in both ferrous and non-ferrous materials across general machining and toolroom environments.
