Accupro 12185097 Square End Mill 0.25in 2 Flute Carbide

Product Description

The ACCUPRO 12185097 is a double-end square end mill designed for precision milling operations in metal fabrication and machining environments. Built from micrograin solid carbide with an AlTiN (aluminum titanium nitride) finish, this tool delivers hardness and heat resistance suited for dry or high-speed cutting applications. The 0.25 inch cutting diameter and 0.5 inch length of cut are optimized for stub-length rigidity. The 40-degree helix spiral flute geometry promotes efficient chip evacuation and reduces cutting forces. This is a centercutting tool, meaning it can plunge directly into a workpiece. Installed by machinists and CNC operators in job shop and production environments.

This end mill fits standard 0.25 inch collets or end mill holders and is suited for slotting, profiling, and plunge milling in ferrous and non-ferrous metals, hardened steels, and similar materials. The double-end design extends usable tool life by providing two cutting ends per shank. The right-hand cut and right-hand flute configuration is standard for conventional CNC milling setups. Stub-length construction keeps deflection low during aggressive passes.

Key Features

• Micrograin solid carbide construction for wear resistance and edge retention
• AlTiN finish improves performance in high-temperature and hard-material cutting
• 40-degree helix angle promotes smooth chip flow and reduces heat buildup at the cutting edge
• Centercutting capability allows direct plunge entry without a pilot hole
• Double-end design provides two usable cutting ends per tool
• Right-hand cut and right-hand flute — standard for conventional CNC milling spindles

Compatibility

Designed for use in standard 0.25 inch collets or end mill holders on CNC machining centers and manual knee mills configured for right-hand rotation.

Installation Notes

Installation is performed by machinists using an appropriate collet or set-screw end mill holder rated for the 0.25 inch shank diameter. Confirm spindle is fully stopped and machine is locked out before changing tooling. Verify shank seating depth meets the holder manufacturer minimum engagement specification. Inspect collet or holder for runout before beginning the cut, as excessive runout accelerates edge wear on carbide tooling.
