Kennametal 6754963 Square End Mill 0.75in 5 Flute Solid Carbide

Product Description

The KENNAMETAL 6754963 is a solid carbide square end mill engineered for high-performance milling in aluminum and non-ferrous materials. Part of the KOR5 series, it features a 0.75-inch mill diameter, five flutes with a 35-degree helix angle, and a 2.25-inch length of cut. The bright, uncoated finish is optimized for non-ferrous applications where coating adhesion or buildup is a concern. A chipbreaker geometry aids in chip evacuation during deep-pocket and slot milling operations. This tool is installed and operated by machinists and CNC tooling specialists in production and job-shop environments.

This end mill is suited for milling aluminum, brass, copper, and other non-ferrous workpieces in both CNC machining centers and manual knee mills. The single-end, centercutting design allows plunge entry as well as peripheral and slot cutting. The right-hand cut and right-hand spiral flute direction are standard for conventional spindle-up machining setups. With a 0.75-inch shank diameter and 5-inch overall length, it fits standard ER and side-lock toolholders common in production environments.

Key Features

• 5-flute solid carbide construction in material grade K600 for rigidity and wear resistance
• 35-degree helix angle promotes smooth cutting action and chip flow in non-ferrous materials
• Chipbreaker geometry reduces chip recutting and aids evacuation in deep-slot applications
• Centercutting design enables direct plunge entry without a pre-drilled pilot hole
• Bright, uncoated finish suitable for aluminum and non-ferrous workpieces where coating buildup is a concern
• Right-hand cut and right-hand flute spiral for standard CNC and manual milling setups

Compatibility

Designed for use with aluminum and non-ferrous workpiece materials (Primary Workpiece Material Code: N). Compatible with standard 0.75-inch-bore ER collet chucks, hydraulic chucks, and side-lock toolholders used in CNC machining centers and manual mills. Part of the KENNAMETAL KOR5 series.

Installation Notes

Installation and tool changes must be performed with the machine spindle fully stopped and the control in a safe, locked-out state per shop lockout/tagout procedures. Seat the 0.75-inch shank fully into the toolholder bore and torque the retention mechanism to the toolholder manufacturer's specification. Verify runout at the cutting diameter with a dial indicator before beginning a production cut. Do not exceed the tool's rated depth of cut or feed rate for the workpiece material and machine spindle power.
