Accupro 12182373 Square End Mill 0.118 in 4 Flute Carbide

Product Description

The ACCUPRO 12182373 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. With a 0.118-inch (3.00 mm) mill diameter and a 0.4724-inch length of cut, this tool is built for tight-tolerance work in small-bore and detail milling operations. The four-flute, spiral configuration with a 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. Manufactured from micrograin solid carbide, it delivers the rigidity and wear resistance required for production-level cutting in ferrous and non-ferrous materials. This is a centercutting tool, allowing plunge entry directly into the workpiece.

This end mill is suited for CNC machining centers and manual milling machines in job shops, tool rooms, and production facilities. The right-hand cut and right-hand flute orientation match standard spindle configurations. Its regular-length body and 3.00 mm shank diameter make it a practical choice for close-clearance slots, pockets, and profiling cuts where a small-diameter carbide tool is required. Machinists and CNC operators working on precision components in steel, aluminum, and similar materials will find this tool appropriate for finish and semi-finish passes.

Key Features

• 0.118-inch (3.00 mm) diameter with mill diameter tolerance of +0.000 / -0.002 inches for consistent fit
• 0.4724-inch (12.00 mm) length of cut suits shallow-to-moderate pocket depths
• 4-flute spiral design with 40-degree helix angle for efficient chip flow and surface finish
• Centercutting geometry allows direct plunge milling without pre-drilling
• Micrograin solid carbide construction provides hardness and edge retention
• Uncoated finish suitable for use with cutting fluids on a wide range of workpiece materials

Compatibility

Designed as a standard replacement or direct-use solid carbide square end mill for CNC machining centers and conventional milling machines accepting a 3.00 mm (0.118-inch) shank diameter tool holder.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator with the machine in a locked-out, zero-energy state before tool changes. Ensure the tool holder collet or end mill adapter is clean and free of debris before seating the shank. Verify runout after installation using a dial indicator before beginning a cut. Consult the machine tool manufacturer and applicable shop safety standards for proper clamping torque and speeds-and-feeds guidance for the workpiece material.
