Accupro 14797252 Square End Mill 0.075 in 3 Flute Carbide

Product Description

The ACCUPRO 14797252 is a solid carbide square end mill designed for precision milling in demanding machining environments. With a 0.075-inch cutting diameter and a 0.112-inch length of cut, this tool is built for tight-tolerance work in small-feature milling applications. The three-flute, right-hand spiral design with a 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. The AlTiN coating adds surface hardness and heat resistance, extending tool life in ferrous and hard alloy materials. Centercutting capability allows for direct plunge entry. The micrograin carbide substrate supports high-speed operation and edge retention. This end mill is typically installed and run by machinists and tool-and-die professionals on CNC machining centers and manual mills.

This end mill suits small-feature milling in production and job-shop environments. The 0.075-inch diameter and extended reach design make it appropriate for slotting, profiling, and pocket milling in confined areas or deep-cavity workpieces. The 1/8-inch shank diameter fits standard collets and toolholders sized for that shank. The 0.625-inch reach length and 2.5-inch overall length provide clearance for applications requiring extended projection from the spindle nose. It is suited for use on aluminum, steel, stainless, and hard alloys where AlTiN-coated carbide tooling is specified.

Key Features

• 0.075-inch cutting diameter with mill diameter tolerance of +0.0000 / -0.0010 inches for close-tolerance work
• AlTiN finish provides heat and wear resistance in ferrous and high-hardness materials
• Three-flute spiral design with 30-degree helix angle for efficient chip evacuation
• Centercutting geometry allows direct plunge milling without a pre-drilled entry hole
• Micrograin solid carbide substrate supports edge retention at elevated cutting speeds
• Extended reach with 0.625-inch reach length and 2.5-inch overall length for deep-cavity access

Compatibility

Designed as an OEM-style replacement or standard tooling selection for CNC machining centers and manual mills equipped with 1/8-inch collets or toolholders.

Installation Notes

This end mill is installed by machinists using standard collet chucks or end mill holders sized for a 1/8-inch shank. The spindle must be fully stopped and the machine powered down before changing tooling. Shank diameter tolerance is -0.0001 / -0.0003 inches; verify holder runout and clamping torque per the toolholder manufacturer specifications to avoid premature tool failure. Do not exceed the recommended depth of cut for the 0.075-inch diameter to prevent tool deflection or breakage.
