Accupro 12276782 Square End Mill 0.005 in 4 Flute Carbide

Product Description

The ACCUPRO 12276782 is a solid carbide square end mill designed for precise milling operations in demanding machining environments. With a 0.005-inch cutting diameter and a 0.015-inch length of cut, this tool is built for micro-milling applications where tight tolerances and fine detail are required. The four-flute geometry with a 30-degree right-hand helix promotes efficient chip evacuation and a smooth finish. Micrograin carbide construction delivers the rigidity and edge retention needed when cutting hardened or abrasive workpiece materials. The bright, uncoated finish makes this tool suitable for a broad range of non-ferrous and ferrous materials.

This end mill is used in CNC machining centers, tool rooms, and precision mold and die operations where micro-scale features must be cut accurately. It fits applications calling for a regular-length, single-end tool with a 0.125-inch shank diameter. The center-cutting design allows plunging directly into the workpiece. Right-hand cutting and right-hand flute direction make it compatible with standard spindle configurations found on most vertical and horizontal machining centers.

Key Features

• 0.005-inch cutting diameter with a mill diameter tolerance of plus 0.0000 / minus 0.0010 inches for micro-feature accuracy
• 0.015-inch length of cut, suited for shallow pocket and micro-slot work
• Four-flute, right-hand spiral configuration for smooth chip flow and surface finish
• Micrograin solid carbide substrate for edge retention in hard and abrasive materials
• Center-cutting capable, allowing direct plunge entry without a pilot hole
• Bright/uncoated finish compatible with a wide range of workpiece materials

Compatibility

Designed as an OEM-style replacement or direct-fit tool for CNC machining centers and manual mills equipped with a standard 0.125-inch collet or tool holder accepting a 0.125-inch shank diameter.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Secure the 0.125-inch shank in a properly sized collet or end mill holder to the torque specification listed by the tool holder manufacturer. Verify runout after installation, as excessive runout at this diameter will cause premature tool failure or part rejection.
