Accupro 14797220 Square End Mill 0.06 in 3 Flute Altin

Product Description

The ACCUPRO 14797220 is a solid carbide square end mill designed for precision milling in demanding metal-cutting applications. Built from micrograin carbide stock and coated with AlTiN (aluminum titanium nitride), this tool delivers extended tool life and heat resistance at elevated cutting speeds. It runs a 0.06-inch mill diameter with a 3/32-inch (0.0900 inch) length of cut and a 1/8-inch shank diameter. The 30-degree right-hand helix promotes efficient chip evacuation. Three flutes provide a balance of chip clearance and edge strength suited to finishing and light roughing passes. Centercutting geometry allows plunge entry. Installed by machinists and tool-and-die professionals on CNC machining centers and manual mills.

This end mill is sized for small-feature work: slots, pockets, and contour passes in ferrous and non-ferrous alloys, stainless steels, hardened steels, and cast iron where AlTiN coating performance is required. The extended-reach configuration, with a 0.3120-inch neck length and 0.1800-inch reach length, provides clearance when milling deep features relative to the tool diameter. The 2.5-inch overall length fits standard ER and straight-shank collet toolholders with a 1/8-inch bore. Single-end construction means the tool is replaced rather than reversed when worn.

Key Features

• AlTiN coating provides high heat resistance and oxidation resistance for dry and semi-dry cutting in ferrous alloys
• Micrograin solid carbide substrate for rigidity and edge retention at small diameters
• 3-flute geometry balances chip room and cutting edge count for small-diameter finishing work
• 30-degree right-hand spiral helix for positive chip evacuation
• Centercutting design supports direct plunge entry without a pre-drilled pilot hole
• Extended-reach neck geometry allows access to recessed features without tool deflection buildup

Compatibility

Designed as an OEM-style replacement or direct application fit for CNC machining centers and manual mills accepting a 1/8-inch straight shank; part of the ACCUPRO ASQSC3-AT-CCER series of AlTiN-coated square end mills.

Installation Notes

A licensed machinist or qualified CNC operator should install this tool in a clean, properly sized 1/8-inch collet or endmill holder, torquing to the toolholder manufacturer specification. Ensure the spindle is fully stopped and the machine is in an e-stop or lockout state before changing tooling. Inspect the collet bore and shank for contamination or wear before seating; a worn collet can induce runout that will break tools at this diameter. Do not exceed the recommended depth-of-cut for the diameter — consult published feeds-and-speeds data for the specific workpiece material and coating type.
