Accupro 12176855 Square End Mill 3/64 in 2 Flute Carbide

Product Description

The ACCUPRO 12176855 is a solid carbide square end mill designed for precision milling in ferrous and non-ferrous materials. With a 3/64 inch (0.0469 inch decimal) mill diameter and a 2-flute spiral configuration, this end mill is built for tight-tolerance profiling, slotting, and contour work in confined geometries. The 30-degree helix angle promotes efficient chip evacuation while keeping cutting forces manageable at small diameters. Micrograin carbide construction provides the rigidity and edge retention needed when working at this scale. The bright/uncoated finish makes it suitable for a wide range of base materials without coating-related concerns.

This end mill is suited for precision machining applications in tool-and-die, mold making, aerospace component work, and general CNC milling where small-diameter, high-accuracy cuts are required. The long-length configuration and extended reach allow access to features in deep pockets or recessed areas that standard-length end mills cannot reach. The right-hand cutting and right-hand flute direction are standard for conventional CNC spindle setups. Centercutting capability allows plunge entry without a pre-drilled pilot hole.

Key Features

• Solid micrograin carbide construction for rigidity and edge retention at small diameters
• 3/64 inch diameter with 9/64 inch length of cut for fine-detail milling
• 30-degree helix angle promotes chip evacuation in spiral flute design
• Extended reach with 0.423 inch reach length for deep-pocket access
• Centercutting geometry allows direct plunge entry
• Bright/uncoated finish compatible with a broad range of workpiece materials

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide end mill for CNC machining centers and manual mills accepting a 1/8 inch shank diameter with standard ER or collet-style toolholding.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully powered down and at a complete stop before changing tooling. Secure the 1/8 inch shank in a properly sized collet or end mill holder, tightening to the toolholder manufacturer's specified procedure. At this diameter, runout control is critical — verify TIR with a dial indicator before commencing a cut to prevent premature tool breakage.
