Accupro 12176872 Square End Mill 3/32 in 3 Flute Carbide

Product Description

The ACCUPRO 12176872 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. With a 3/32 inch (0.0938 inch) cutting diameter and a 3/8 inch length of cut, this tool is suited for fine detail work in slots, pockets, and profiles. The micrograin carbide construction provides hardness and wear resistance across a range of workpiece materials. Three spiral flutes with a 30-degree helix angle promote efficient chip evacuation and a smooth cutting action. The uncoated finish makes this a straightforward, versatile choice for general-purpose milling where coating is not required.

This end mill is intended for use in CNC machining centers, manual knee mills, and benchtop machines where small-diameter tooling is required. The 1/8 inch shank diameter fits standard collets and tool holders common in light-duty and precision machining setups. Its regular-length geometry and 1-1/2 inch overall length make it appropriate for shallow-to-moderate depth cuts in ferrous and non-ferrous materials. Machinists working on mold details, prototype parts, or close-tolerance features will find this tool well suited to the task.

Key Features

• 3/32 inch cutting diameter with a mill diameter tolerance of +0.0002 / -0.0008 inches for precise fitment
• Micrograin solid carbide construction for hardness and extended tool life
• 3 spiral flutes with 30-degree helix angle for efficient chip evacuation
• Centercutting design allows plunge entry directly into the workpiece
• Right-hand cut and right-hand flute configuration, standard for most machining setups
• Uncoated finish for versatile use across general-purpose milling applications

Compatibility

Designed as an OEM-style replacement or direct-fit tooling option for 1/8 inch collet and tool holder systems used in CNC and manual milling machines requiring small-diameter square end mills.

Installation Notes

Installation should be performed by a qualified machinist following standard toolholding procedures. Ensure the machine spindle is fully powered down and locked before inserting or removing tooling. Seat the shank fully into the collet or holder to the recommended engagement depth and torque the retention mechanism per the tool holder manufacturer specifications. Verify runout with a dial indicator before beginning a cut to avoid premature tool wear or dimensional error.
