Accupro 12176844 Square End Mill 1/32 in 2 Flute Carbide

Product Description

The ACCUPRO 12176844 is a solid carbide square end mill designed for precision milling in tight-tolerance applications. Built from micrograin carbide, it delivers the rigidity and edge retention needed when cutting ferrous and non-ferrous materials at small diameters. The 1/32 inch (0.0313 inch) cutting diameter and 1/16 inch length of cut make it well suited for fine detail work, micro-slotting, and finishing passes in hardened materials. With a 30-degree helix angle and spiral flute geometry, it promotes efficient chip evacuation even in confined cuts. This is a right-hand cut, right-hand flute, centercutting tool sold as a single unit.

This end mill is intended for use in CNC machining centers, manual knee mills, and high-speed spindle applications where small-diameter tooling is required. Its stub-length configuration provides added rigidity, reducing deflection during fine milling operations on molds, dies, and intricate part features. The 1/8 inch shank fits standard collets and tool holders commonly found in production and job-shop environments. It is appropriate for machinists and toolroom professionals working with aluminum, brass, plastics, and steels where micro-detail cutting is specified.

Key Features

• Micrograin solid carbide construction for superior wear resistance and edge integrity at small diameters
• 1/32 inch cutting diameter with 0.0313 inch decimal equivalent and tight mill diameter tolerance of +0.0002 / -0.0008 inches
• 30-degree helix angle with spiral flute geometry for efficient chip evacuation
• Centercutting capable, allowing plunge entry into the workpiece
• Stub-length (1-1/2 inch OAL) design maximizes rigidity and minimizes deflection
• Uncoated finish suitable for a broad range of base materials without coating-compatibility concerns

Compatibility

Designed as a direct-fit replacement or standard tooling selection for any setup requiring a 1/8 inch shank, 1/32 inch diameter square end mill in a stub-length configuration with a standard collet or end mill holder.

Installation Notes

Installation should be performed by a qualified machinist following shop safety protocols. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the 1/8 inch shank securely in a clean, undamaged collet or tool holder and verify runout with a dial indicator before beginning the cut. Due to the small cutting diameter, excessive feed rates or lateral load can cause tool breakage — follow the tooling manufacturer's recommended speeds and feeds for the specific workpiece material.
