Accupro 14797231 Square End Mill 1/16 in 3 Flute Carbide

Product Description

The ACCUPRO 14797231 is a solid carbide square end mill designed for precision milling in a wide range of metalworking and machining applications. With a 1/16 inch (0.0625 inch) mill diameter and a 30-degree helix angle, this tool delivers clean, accurate cuts in tight-tolerance work. The micrograin carbide construction provides hardness and wear resistance suitable for ferrous and non-ferrous materials. Three right-hand flutes with a spiral flute form support efficient chip evacuation. The bright, uncoated finish is well-suited for general-purpose cutting where coating is not required. Machinists and toolroom professionals install and operate this tool on CNC machining centers and manual mills.

This end mill is built for single-end use and features an extended reach configuration, making it applicable in slotting, profiling, and plunge-cutting operations where access to deeper or recessed features is needed. The 0.093 inch length of cut (LOC) and 1/8 inch shank diameter make it appropriate for small-part and detail work on precision components. It is centercutting, allowing direct plunge entry without pre-drilling. Typical applications include mold and die work, medical component machining, electronics hardware, and other industries requiring small-diameter tooling with tight dimensional tolerances.

• 3 right-hand spiral flutes for efficient chip evacuation during cutting
• 30-degree helix angle supports smooth cutting action and reduced chatter
• Centercutting geometry allows direct plunge entry
• Extended reach with a 0.186 inch reach length and 0.312 inch neck length for access in recessed features
• Bright/uncoated finish for general-purpose use across a range of work materials

Compatibility

Designed as a standard 1/8 inch shank square end mill compatible with collets, end mill holders, and tool chucks sized for 1/8 inch shank tooling on CNC machining centers and manual milling machines.

Installation Notes

Installation and operation should be performed by qualified machinists familiar with small-diameter carbide tooling. Ensure the tool holder and collet are clean, properly sized for the 1/8 inch shank, and torqued to the machine manufacturer's specification before use. Small-diameter carbide end mills are brittle - avoid side loading, interrupted cuts, or excessive runout, as these conditions increase the risk of tool breakage. Verify spindle speed and feed rate settings against published cutting data for the specific work material before beginning a cut.
