Accupro 14796913 Square End Mill 0.045 in 2 Flute Altin

Product Description

The ACCUPRO 14796913 is a solid carbide square end mill designed for precision milling of ferrous and non-ferrous metals in CNC machining environments. It features a 0.045-inch cutting diameter, a 0.135-inch length of cut, and a 30-degree helix angle. The AlTiN (aluminum titanium nitride) coating improves heat resistance and extends tool life in high-speed dry or semi-dry cutting applications. The micrograin carbide substrate provides edge sharpness and rigidity at small diameters. This tool is installed and used by machinists and toolroom technicians on CNC mills and machining centers.

This end mill is suited for slotting, profiling, and contouring operations requiring a small-diameter tool. The 0.125-inch shank diameter fits standard collets and tool holders common in CNC milling setups. With a 1.5-inch overall length and regular-length classification, it is appropriate for shallow-to-moderate depth work where rigidity and runout control are critical. The right-hand cutting and right-hand flute direction are standard for conventional CNC milling spindles.

Key Features

• 0.045-inch cutting diameter with mill diameter tolerance of +0.0000 / -0.0010 inches for precise fitment
• AlTiN coating for elevated heat resistance in high-speed cutting
• Micrograin solid carbide substrate for rigidity and sharp edge retention at micro diameters
• 30-degree helix angle promotes smooth chip evacuation in spiral flute geometry
• Centercutting design allows plunge entry into workpiece material
• 2-flute configuration optimized for chip clearance in tight-diameter cuts

Compatibility

Designed as a standard single-end square end mill compatible with CNC milling machines and machining centers using 0.125-inch bore collets or tool holders accepting a 1/8-inch shank diameter.

Installation Notes

Installation and tool changes should be performed with the machine spindle fully powered down and locked. Use a calibrated collet or end mill holder sized for the 0.125-inch shank and ensure the shank is seated to the full recommended engagement depth before tightening. Verify runout with a dial indicator before initiating the cut, as small-diameter carbide end mills are sensitive to excessive runout. Handle micrograin carbide tooling carefully to avoid edge chipping during loading and unloading.
