Accupro 12182325 Square End Mill 3/64 in 4 Flute Carbide

Product Description

The ACCUPRO 12182325 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. With a 3/64 inch (0.0469 inch) mill diameter and four spiral flutes at a 30-degree helix angle, it delivers clean cuts in tight geometries where larger tooling cannot reach. The micrograin carbide construction provides edge retention and rigidity at small diameters. This is a centercutting, single-end tool with right-hand cut and right-hand flute orientation. It is sized for use in CNC machining centers, vertical mills, and precision toolrooms where close-tolerance work is standard.

This end mill suits finish milling, slotting, and profiling operations in ferrous and non-ferrous materials. Its 9/64 inch length of cut and 1-1/2 inch overall length make it appropriate for shallow-depth passes in detailed part features, cavity work, and small-bore slot milling. The 1/8 inch shank diameter fits standard collets and toolholders found in most light-duty CNC and manual mill setups. No coating is applied, making it a straightforward choice for general-purpose machining where coating selection is left to the application.

Key Features

• Solid micrograin carbide construction for rigidity and edge retention at 0.0469 inch diameter
• 4 spiral flutes with 30-degree helix angle for efficient chip evacuation
• Centercutting geometry allows direct plunge entry
• Right-hand cut and right-hand flute orientation for standard spindle compatibility
• Uncoated finish for versatile general-purpose use
• Regular length type with 9/64 inch length of cut for controlled shallow passes

Compatibility

Designed as a direct-fit replacement or standard toolroom end mill for setups using 1/8 inch collets or toolholders. Consult machine tooling specs to confirm runout tolerances before use with this diameter.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the 1/8 inch shank fully into the collet and torque the collet nut to the toolholder manufacturer's specification. At this diameter, runout control is critical — verify TIR before initiating a cut.
