Accupro 14797053 Square End Mill 0.037 in 4 Flute Altin

Product Description

The ACCUPRO 14797053 is a solid carbide square end mill designed for high-precision milling operations in metalworking and machining applications. Built from micrograin solid carbide and finished with an AlTiN (aluminum titanium nitride) coating, it handles elevated cutting temperatures and abrasive materials with consistent dimensional accuracy. The 0.037 inch cutting diameter and 0.055 inch length of cut make it well-suited for fine detail work, slotting, and profiling in tight geometries. A 30-degree helix angle and four-flute spiral configuration promote efficient chip evacuation while maintaining surface finish quality. This end mill is a single-end tool with right-hand cutting and right-hand flute direction.

This end mill is used in precision CNC machining centers and manual mills for cutting ferrous and non-ferrous metals, hardened steels, and superalloys where heat resistance and edge retention are critical. Its micro-diameter geometry makes it appropriate for die and mold work, medical component machining, aerospace detail parts, and any application requiring tight tolerances at small scales. The centercutting capability allows plunge entry as well as conventional side milling and slotting passes.

Key Features

• AlTiN coating provides high-temperature oxidation resistance for dry and semi-dry cutting
• Micrograin solid carbide substrate delivers hardness and rigidity at 0.037 inch diameter
• 4-flute spiral design balances chip load and surface finish in finishing passes
• 30-degree helix angle promotes smooth cutting action and chip evacuation
• Centercutting geometry allows direct plunge entry without a pre-drilled pilot hole
• Right-hand cut and right-hand helix for standard CNC spindle compatibility

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide end mill for CNC machining centers and manual mills accepting a 0.125 inch straight shank tool holder or collet.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully powered down and the machine is in a safe state before changing tooling. Secure the 0.125 inch shank in a properly sized collet or end mill holder torqued to the machine manufacturer specification. At micro diameters, runout control is critical — verify TIR with a dial indicator before beginning a production run to avoid tool breakage.
