Accupro 12177064 Square End Mill 3/64 in 4 Flute Carbide

Product Description

The ACCUPRO 12177064 is a solid carbide square end mill designed for precision milling in tight geometries and small-feature applications. With a 3/64 inch (0.0469 inch) cutting diameter and a 9/64 inch (0.1406 inch) length of cut, this tool is built for fine detail work in hardened materials, mold work, and intricate part profiles. The four-flute, spiral-flute geometry with a 40-degree helix angle promotes efficient chip evacuation while maintaining a stable cut. Micrograin carbide construction delivers rigidity and wear resistance in demanding applications. This is a centercutting, right-hand cut, right-hand flute configuration, making it suitable for both plunge and peripheral milling operations.

This end mill is intended for use in CNC machining centers and manual mills where small-diameter tooling is required. Typical applications include slotting, profiling, and pocket milling in ferrous and non-ferrous materials. The 1/8 inch shank diameter is standard for small-diameter collet systems and tool holders commonly found in production and toolroom environments. Machinists working in mold and die, aerospace component finishing, or precision prototype work will find this tool well suited to close-tolerance operations.

Key Features

• 3/64 inch cutting diameter with +0.0005/-0.0000 inch mill diameter tolerance for close-tolerance work
• Micrograin solid carbide construction for rigidity and extended tool life
• 4-flute, spiral-flute design with 40-degree helix angle for efficient chip evacuation
• Centercutting capability allows direct plunge entry without pre-drilling
• Right-hand cut and right-hand flute configuration for standard spindle use
• Uncoated finish suitable for a range of base materials without coating compatibility concerns

Compatibility

Designed as a standard small-diameter square end mill compatible with 1/8 inch collets and tool holders used in CNC machining centers and conventional milling machines.

Installation Notes

Installation should be performed by a qualified machinist following shop safety protocols. Secure the shank fully within the collet to the recommended grip length and torque the collet nut according to the tool holder manufacturer specifications. Verify spindle runout before operation to avoid premature tool breakage, which is a significant risk with small-diameter carbide tooling. Never exceed the recommended depth of cut or feed rate for the tool diameter in use.
