Accupro 14556355 Square End Mill 1/8 in 4 Flute Solid Carbide

Product Description

The ACCUPRO 14556355 is a solid carbide square end mill designed for precision milling in demanding metalworking applications. With a 0.125-inch mill diameter, 0.25-inch length of cut, and a 1.5-inch overall length, this stub-length tool is built for rigidity and accurate edge finishing. The 4-flute geometry with a 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. An AlTiN+ coating provides thermal resistance and extended tool life in ferrous and high-temperature alloy materials. The straight-cylindrical shank and right-hand cut with right-hand flute configuration make this a standard setup for CNC machining centers and manual knee mills.

This end mill is suited for slotting, profiling, and peripheral milling operations in ferrous metals, stainless steel, and high-temperature alloys where heat resistance and edge retention are priorities. The stub-length design reduces deflection and improves dimensional accuracy in tight-tolerance work. Centercutting capability allows direct plunge entry into the workpiece. It is a single-end tool intended for use by machinists, tool-and-die makers, and CNC operators working in job shop or production environments.

Key Features

• 0.125-inch mill diameter with mill diameter tolerance of +0.000 to -0.002 inches for consistent sizing
• AlTiN+ coating for thermal resistance and extended tool life in ferrous and high-temperature alloy applications
• 4-flute spiral flute geometry with 40-degree helix angle for efficient chip flow and surface finish
• Centercutting design allows plunge milling without a pre-drilled pilot hole
• Micrograin solid carbide construction for wear resistance and edge sharpness retention
• Straight-cylindrical shank with shank diameter tolerance of -0.0001/-0.0004 inches for consistent tool holder fit

Compatibility

Designed as an OEM-style solid carbide square end mill for use in standard straight-bore end mill holders and collet chucks accepting a 0.125-inch shank diameter. Part of the ACCUPRO Series 6/44 stub-length end mill line.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Seat the shank fully into the tool holder and torque the retention fastener to the tool holder manufacturer specification. Verify runout with a dial indicator before beginning a cut to confirm proper seating and minimize tool deflection.
