Internal Tool 64-1429 Carbide Chamfer Mill 3/4 in

Product Description

The INTERNAL TOOL 64-1429 is a solid carbide double-end chamfer mill designed for chamfering and countersinking operations across a wide range of workpiece materials. The 90-degree included angle and 0.75-inch cutter head diameter make it well suited for producing clean, consistent chamfers in production and job-shop environments. The double-end configuration extends usable tool life by providing two cutting ends on a single shank. Right-hand cutting direction and a bright, uncoated finish are standard. This tool is installed and operated by machinists and CNC programmers working with mills, machining centers, and manual knee mills.

This chamfer mill is appropriate for use on aluminum, aluminum alloy, brass, bronze, copper, cast 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 broad material compatibility makes it a practical choice for general-purpose chamfering work in job shops handling mixed-material runs or prototype work.

Key Features

• Solid carbide construction for rigidity and wear resistance across ferrous and non-ferrous materials
• 90-degree included angle for standard chamfer and countersink geometry
• Double-end design provides two usable cutting ends per tool
• Right-hand cutting direction, compatible with standard spindle rotation
• Bright, uncoated finish suitable for use with or without coolant
• No coolant-through requirement simplifies setup

Compatibility

Designed as a direct-fit chamfer mill for machining centers and manual mills accepting a 0.75-inch shank diameter. Compatible with standard ER or side-lock toolholders sized for a 0.75-inch shank.

Installation Notes

Installation is performed by a machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in an e-stop or locked-out state before loading or unloading the tool. Seat the shank fully into the toolholder to the recommended grip depth before torquing the retention mechanism. Verify runout at the cutter head after installation to avoid premature edge wear or poor chamfer quality.
