Internal Tool 64-1426 Carbide Chamfer Mill 90 Deg Double End

Product Description

The INTERNAL TOOL 64-1426 is a solid carbide double-end chamfer mill designed for chamfering and countersinking operations across a wide range of workpiece materials. Built with a 90-degree included angle and a 0.625-inch cutter head diameter, this tool delivers consistent edge preparation and deburring performance on both manual and CNC machining setups. The double-end configuration extends usable tool life by providing two cutting ends in a single shank. The right-hand cutting direction and uncoated solid carbide construction make it well suited for shops requiring a reliable general-purpose chamfer tool without specialty coatings.

This chamfer mill is intended for use on milling machines and machining centers in job shop, production, and maintenance environments. It is suited for chamfering, deburring, and countersinking on a broad material range including aluminum, aluminum alloy, brass, bronze, copper, cast iron, iron, magnesium, molybdenum, Monel, plastic, steel, stainless steel, titanium, high-nickel steel, copper alloy, magnesium alloy, nickel base alloy, low-carbon steel, and medium-carbon steel. The 0.310-inch length of cut and 3.5-inch overall length make it appropriate for standard benchtop and vertical mill applications.

Key Features

Compatibility

Designed as an OEM-style replacement chamfer mill for use in standard 0.625-inch diameter collet chucks and end mill holders on milling machines and CNC machining centers.

Installation Notes

Installation should be performed by a qualified machinist or toolroom professional. Ensure the machine spindle is fully stopped and locked out before changing tooling. Secure the shank in a properly sized collet or end mill holder torqued to the machine manufacturer's specification. Confirm cutting direction matches spindle rotation before initiating a cut.
