Accupro 95168406 Square End Mill 1/8 in 5 Flute Carbide

Product Description

The ACCUPRO 95168406 is a 5-flute solid carbide square end mill designed for precision milling in demanding cutting applications. Built from micrograin carbide stock and finished with an nACRo coating, this tool delivers extended wear resistance and thermal stability at the cutting edge. The variable helix geometry reduces harmonic chatter, improving surface finish and allowing more aggressive feed rates. At 1/8 inch diameter with a 3/4 inch length of cut and 3 inch overall length, this end mill targets tight-tolerance slotting, profiling, and finishing passes in ferrous and non-ferrous materials. It is installed by machinists and tool-and-die professionals working on CNC machining centers and manual mills.

This end mill suits applications requiring fine-feature machining in hardened steels, stainless, titanium, and high-temperature alloys where heat generation and tool deflection are primary concerns. The single-end, center-cutting design allows direct plunge entry or ramping into workpiece material. The 1/8 inch shank diameter matches standard collet and end mill holder sizes found on most CNC and manual milling equipment. Typical use cases include mold and die work, aerospace component machining, and precision part production runs where consistent tool life and surface finish are critical.

Key Features

• Solid micrograin carbide substrate for superior hardness and edge retention
• nACRo coating provides oxidation resistance and reduced friction at elevated cutting temperatures
• Variable helix flute geometry suppresses vibration and chatter during cutting
• 5-flute configuration increases chip load capacity and improves surface finish over 4-flute alternatives
• Center-cutting design allows plunge and ramp entry without a pre-drilled pilot hole
• Right-hand cut and right-hand flute spiral for standard CNC spindle compatibility

Compatibility

Designed as a direct-fit replacement-style solid carbide square end mill for standard 1/8 inch collet and end mill holder tooling systems on CNC machining centers and manual milling machines.

Installation Notes

Installation requires a clean, properly sized collet or end mill holder matched to the 1/8 inch shank diameter. Inspect the shank and collet bore for chips or debris before seating the tool, as contamination affects runout and tool life. Apply appropriate torque to the collet nut per the toolholder manufacturer specification. Confirm spindle speed and feed rate are set per the material and coating manufacturer recommendations before engaging the cut.
