Accupro 317216 Square End Mill 0.5in 8 Flute Solid Carbide

Product Description

The ACCUPRO 317216 is a solid carbide square end mill designed for high-performance material removal in milling operations. With a 0.5 inch cutting diameter, 8 flutes, and a 40-degree helix angle, this end mill delivers efficient chip evacuation and smooth surface finishes in demanding machining environments. The AlTiCrN coating provides enhanced heat and wear resistance, making it well suited for dry or high-speed cutting in hardened materials. Micrograin carbide construction contributes to edge sharpness and tool longevity. This tool is installed and operated by machinists and CNC tooling professionals working in production and job-shop settings.

The 317216 is built for use in vertical and horizontal milling centers, CNC machining centers, and manual mills where a single-end, right-hand cut tool is required. With a 1.25 inch length of cut and a 3 inch overall length, it fits standard 0.5 inch collets and end mill holders. The spiral flute geometry and right-hand flute direction make this tool appropriate for general-purpose profiling, slotting, and contouring operations on metals and other machinable materials.

Key Features

• 8-flute geometry supports higher feed rates and improved surface finish compared to lower flute-count tools
• 40-degree helix angle promotes efficient chip flow and reduces cutting forces
• AlTiCrN coating provides thermal and abrasion resistance for extended tool life in ferrous and hardened materials
• Micrograin solid carbide construction delivers consistent edge integrity under heavy cutting loads
• Center-cutting capable, allowing plunge entry directly into the workpiece
• Right-hand cut and right-hand flute direction compatible with standard spindle rotation on most milling machines

Compatibility

Designed as an OEM-style replacement and production tooling option for milling applications requiring a 0.5 inch shank, single-end square profile end mill in the HS series.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Always power down and lock out the spindle before inserting or removing cutting tools. Ensure the shank is fully seated in a clean, properly sized collet or end mill holder and torque to the tool holder manufacturer's specification. Inspect the cutting edges and coating for chips or wear before each use and replace tooling at the first sign of edge degradation to avoid workpiece damage.
