Accupro 12181247 Square End Mill 0.0984 in 2 Flute Carbide

Product Description

The ACCUPRO 12181247 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. With a 0.0984 inch (2.5 mm) mill diameter and a 0.374 inch length of cut, this tool handles slotting, profiling, and peripheral milling in tight geometries. The AlTiN coating provides thermal resistance and hardness for dry or high-speed cutting in ferrous materials. A 30-degree helix angle promotes smooth chip evacuation, reducing heat buildup at the cutting edge. This tool is suited for machinists and CNC operators working in job shops, tool rooms, and production environments.

This end mill is built for use in vertical machining centers, CNC mills, and manual knee mills where small-diameter tooling is required. The 0.1181 inch (3.00 mm) shank fits standard collets and tool holders in that size range. Its regular length profile keeps overhang minimal, improving rigidity and surface finish in close-tolerance work. The centercutting geometry allows plunge entry as well as conventional side milling. Applications include die and mold work, aerospace component machining, and precision part production where tight tolerances are critical.

Key Features

• 0.0984 inch (2.5 mm) mill diameter with mill diameter tolerance of +0.000 / -0.002 inches
• AlTiN coating for high-temperature resistance and extended tool life in ferrous materials
• 30-degree helix angle with spiral flute geometry for efficient chip evacuation
• Centercutting design allows plunge milling and full-slot entry
• Micrograin solid carbide construction for rigidity and wear resistance
• Right-hand cut, right-hand flute configuration — standard orientation for most CNC setups

Compatibility

Designed for use in standard collet systems and toolholders accepting a 3.00 mm (0.1181 inch) shank diameter. Suitable for CNC vertical machining centers and manual mills configured for small-diameter solid carbide end mills.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and the tool changer or collet is de-energized before installing or removing the end mill. Use a properly sized collet or shrink-fit holder to achieve the shank tolerance fit; do not exceed the recommended stick-out for the diameter. Verify runout with a dial indicator before production cuts to protect both the tool and the workpiece.
