Accupro 14797149 Square End Mill 0.02 in 3 Flute Carbide

Product Description

The ACCUPRO 14797149 is a solid carbide square end mill designed for precision metal-removal operations in demanding machining environments. Built from micrograin carbide and coated with AlTiN (aluminum titanium nitride), it delivers hardness and heat resistance suited for ferrous and high-temperature alloy materials. The cutting diameter measures 0.02 inches, with a 0.03-inch length of cut and an overall length of 2.5 inches. Three right-hand spiral flutes with a 30-degree helix angle promote efficient chip evacuation and surface finish. This is a single-end, centercutting tool, meaning it can plunge as well as profile. Machinists and tool-and-die professionals use this end mill for micro-milling applications requiring tight tolerances.

This end mill is suited for high-speed milling operations on hardened steels, stainless, titanium, and similar difficult-to-machine materials. The extended-reach geometry, with a reach length of 0.16 inches, allows access to features in recessed areas without sacrificing rigidity. The 1/8-inch shank diameter is compatible with standard collets and end mill holders found on CNC machining centers and manual mills. It is a single-piece tool with no replaceable inserts, making setup straightforward for production or prototype work.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance at small diameters
• AlTiN coating provides thermal protection and extends tool life in ferrous and high-alloy materials
• Three right-hand spiral flutes with 30-degree helix angle for efficient chip evacuation
• Centercutting design allows both plunge and peripheral milling
• Extended reach geometry with 0.16-inch reach length for access to recessed features
• Mill diameter tolerance of +0.0000 / -0.0010 inches for consistent sizing

Compatibility

Designed for use with standard 1/8-inch collets and end mill holders on CNC machining centers, CNC routers, and manual vertical mills capable of accepting small-diameter tooling.

Installation Notes

Installation should be performed by a qualified machinist or toolroom professional. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Seat the shank fully in the collet or holder to the recommended grip depth and torque the retention nut per the tool holder manufacturer specifications. Inspect the cutting edges under magnification before use, as micro-diameter carbide tools are brittle and can arrive with edge damage if mishandled.
