Accupro 12277049 Square End Mill 0.04 in 4 Flute Carbide

Product Description

The ACCUPRO 12277049 is a solid carbide square end mill designed for precision milling operations in ferrous and non-ferrous materials. With a 0.04 inch cutting diameter and a 0.06 inch length of cut, this tool is built for fine-detail work in tight geometries. The four-flute, right-hand spiral configuration at a 30-degree helix angle promotes efficient chip evacuation and a smooth surface finish. Manufactured from micrograin solid carbide, the 12277049 delivers the rigidity and wear resistance needed in high-speed milling applications. It ships with a bright, uncoated finish and is centercutting-capable, allowing plunge entry where required.

This end mill is suited for light-depth profiling, slotting, and contouring passes in machining centers and CNC mills. Its 0.125 inch shank diameter fits standard collet systems commonly found in benchtop and production milling equipment. The 1.5 inch overall length keeps deflection low during small-feature work. Machinists, tool and die technicians, and precision fabricators working on small-part programs will find this tool appropriate for finishing passes and detail cuts requiring close tolerances.

Key Features

• 0.04 inch cutting diameter with a mill diameter tolerance of +0.0000 / -0.0010 inches for tight dimensional control
• 4 right-hand spiral flutes at a 30-degree helix angle for efficient chip flow
• Micrograin solid carbide construction for hardness and edge retention
• Centercutting design allows direct plunge entry into the workpiece
• Bright, uncoated finish suitable for general-purpose milling across a range of materials
• Single-end configuration; 0.125 inch shank with a tolerance of -0.0001 / -0.0003 inches

Compatibility

Designed as a standard-shank replacement or working tool for CNC machining centers and manual mills equipped with collet systems accepting a 0.125 inch round shank. Part of the ACCUPRO ASQSC4-CC-30H series.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully powered down and the machine is in a safe, locked-out state before changing tooling. Seat the shank fully into the collet and torque the collet nut per the machine manufacturer's specification. Verify runout with a dial indicator before beginning a production cut, particularly given the small diameter of this tool which is sensitive to excessive runout.
