Accupro 14797058 Square End Mill 0.055in 4 Flute Altin

Product Description

The ACCUPRO 14797058 is a solid carbide square end mill designed for precision milling operations in metalworking and machining applications. Built from micrograin solid carbide and coated with AlTiN (aluminum titanium nitride), it delivers extended tool life and heat resistance at elevated cutting speeds. The 0.055-inch cutting diameter and 0.082-inch length of cut make it well-suited for fine-feature work, slotting, profiling, and pocket milling in hardened steels, stainless steels, and high-temperature alloys. With four flutes and a 30-degree helix angle, it balances chip evacuation with surface finish quality in demanding cuts.

This end mill fits conventional CNC machining centers, vertical mills, and high-speed spindle applications where tight-tolerance, small-diameter tooling is required. It is a single-end, right-hand cut tool with right-hand flute direction, appropriate for standard climb and conventional milling passes. The 1/8-inch shank diameter suits collet chucks and end mill holders commonly found in production and job-shop environments. It is center-cutting, allowing direct plunge entry where the application calls for it.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance in hard materials
• AlTiN coating provides thermal barrier and oxidation resistance at high cutting speeds
• Four-flute, 30-degree helix design balances material removal rate with surface finish
• Center-cutting geometry allows plunge milling without a pre-drilled pilot hole
• Right-hand cut and right-hand spiral for compatibility with standard CNC spindle configurations
• 0.055-inch diameter with tight mill diameter tolerance of +0.0000 / -0.0010 inches for precision fitment

Compatibility

Part of the ACCUPRO ASQSC4-AT-CC-30H series. Designed as a direct-fit solid carbide square end mill for use in standard 1/8-inch collet chucks and end mill holders on CNC machining centers and manual mills.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in an e-stop or locked-out state before changing tooling. Seat the shank fully and evenly in the collet or holder and torque the retention nut to the tool holder specification. Verify runout with a dial indicator before beginning the first cut, as excessive runout on small-diameter end mills accelerates tool wear and breakage.
