Accupro 12178809 Square End Mill 3/32 in 2 Flute Carbide

Product Description

The ACCUPRO 12178809 is a solid carbide square end mill designed for precision milling in ferrous and non-ferrous materials. With a 3/32 inch (0.0938 inch) mill diameter and a 5/16 inch length of cut, this tool is built for fine detail work in slots, pockets, and profiles. The 2-flute spiral configuration with a 30-degree helix angle promotes efficient chip evacuation and clean cutting action. Micrograin carbide construction delivers the hardness and wear resistance needed for consistent performance in demanding machining environments. The uncoated finish makes it suitable for applications where coating interaction with the workpiece material is a concern.

This end mill is used in CNC machining centers, manual mills, and toolroom applications where small-diameter precision cutting is required. The 1/8 inch shank diameter fits standard collets and tool holders common in both production and prototype work. Its centercutting design allows direct plunge entry into the workpiece. The right-hand cut and right-hand flute orientation are standard for conventional milling setups. This tool is appropriate for machinists, tool and die makers, and CNC operators working with aluminum, brass, plastics, and similar materials.

Key Features

• Solid micrograin carbide construction for hardness and extended tool life
• 2-flute spiral design with 30-degree helix angle for efficient chip evacuation
• Centercutting geometry allows direct plunge milling without pre-drilling
• Right-hand cut and right-hand flute for standard milling setups
• Uncoated finish suitable for a broad range of workpiece materials
• Regular length classification with 1-1/2 inch overall length for compact reach

Compatibility

Designed as an OEM-style replacement or direct-fit tool for standard 1/8 inch collet and tool holder systems used in CNC and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully powered down and locked before changing tooling. Seat the shank fully into the collet to the recommended engagement depth and torque the collet nut according to the tool holder manufacturer specifications. Verify runout with a dial indicator before beginning the cut to protect both the tool and the workpiece.
