Accupro 14796964 Square End Mill 0.05in 4 Flute Carbide Altin

Product Description

The ACCUPRO 14796964 is a solid carbide square end mill designed for precision milling operations in ferrous and non-ferrous materials. At 0.05 inches in diameter with a 0.15-inch length of cut, this is a micro end mill built for fine detail work, tight-tolerance slots, and small-feature profiling. The AlTiN (aluminum titanium nitride) coating extends tool life in high-heat applications by providing a hard, oxidation-resistant surface layer. With 4 flutes and a 30-degree helix angle, it balances chip evacuation with cutting stability. Machinists and tool-and-die professionals working on CNC milling centers are the primary installers and users of this tool.

This end mill suits small-part machining environments where precision is critical — including mold and die work, medical component machining, aerospace detail parts, and electronics fixtures. The 1/8-inch shank diameter makes it compatible with standard ER collet systems and micro tool holders commonly found on vertical machining centers and high-speed spindles. Right-hand cutting and right-hand flute direction follow standard convention for most CNC milling setups. The regular length designation and 1.5-inch overall length keep deflection low, which matters at this diameter.

Key Features

• Solid carbide micrograin construction for rigidity and edge retention at small diameters
• AlTiN coating provides heat and wear resistance in ferrous and hardened material cuts
• 4-flute, 30-degree helix design balances chip clearing with surface finish quality
• Centercutting capable — supports plunge and ramp entry moves
• Right-hand cut and right-hand spiral for standard CNC spindle compatibility
• Mill diameter tolerance of +0.0000 / -0.0010 inches for tight-fit slot work

Compatibility

Designed for use with 1/8-inch ER collet chucks and compatible micro tool holders on CNC vertical machining centers and high-speed milling spindles. Shank diameter tolerance of -0.0001 / -0.0003 inches ensures consistent seating in precision collet systems.

Installation Notes

Installation and use of this end mill should be performed by qualified machinists familiar with CNC tooling setup and high-speed cutting parameters. Ensure the spindle is fully stopped and the machine is in an e-stop or locked-out state before changing tooling. Seat the shank fully in the collet to the recommended engagement depth and verify runout with a dial indicator before cutting. At 0.05 inches in diameter, this tool is sensitive to excessive runout, improper feeds and speeds, and side loading — follow the manufacturer or tooling reference source for recommended cutting parameters.
