Accupro 14796973 Square End Mill 0.059in 4 Flute Altin

Product Description

The ACCUPRO 14796973 is a single-end, 4-flute square end mill designed for precision milling in ferrous and hardened materials. Built from micrograin solid carbide and coated with AlTiN (aluminum titanium nitride), it handles high-heat cutting environments where standard coatings break down. The cutting diameter is 0.059 inches with a 0.177-inch length of cut, a 1/8-inch shank diameter, and a 1.5-inch overall length. The 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. Right-hand cut and right-hand flute direction are standard on this tool. It is centercutting, allowing plunge entry directly into the workpiece.

This end mill is suited for close-tolerance slotting, profiling, and pocket milling in small-feature applications. The sub-1/8-inch diameter makes it a fit for fine detail work in die and mold machining, aerospace components, and precision instrument parts. It is used in CNC machining centers and manual mills where tight dimensional accuracy is required. The micrograin carbide substrate supports higher surface footage than standard carbide grades, making it appropriate for hardened steels and cast iron as well as aluminum alloys.

Key Features

• Micrograin solid carbide construction for superior wear resistance and edge retention
• AlTiN coating provides high-temperature oxidation resistance for dry or minimal-lubrication cutting
• 4-flute geometry increases feed rate capability compared to 2-flute designs
• 30-degree helix angle promotes chip flow and reduces cutting forces
• Centercutting design allows direct plunge milling without pre-drilling
• Mill diameter tolerance of +0.0000/-0.0010 inches ensures close-tolerance fitment in precision applications

Compatibility

Designed for use in CNC machining centers and manual mills accepting a 1/8-inch shank. Suitable for ferrous metals, hardened steels, cast iron, and non-ferrous materials in small-feature milling applications.

Installation Notes

Install and remove end mills only with the spindle fully stopped and machine power isolated. Use a properly sized collet or end mill holder matched to the 0.125-inch shank diameter to maintain runout within acceptable limits. Inspect the cutting edges and coating condition before each use — chipped or worn edges on carbide tooling should not be reused in precision work. Follow machine tool manufacturer guidelines and applicable shop safety standards for tool change procedures.
