Accupro 14883446 Square End Mill 5/64 in 3 Flute Carbide

Product Description

The ACCUPRO 14883446 is a single-end square end mill designed for precision milling operations in metal and hard material applications. Built from micrograin solid carbide and finished with an AlTiN (aluminum titanium nitride) coating, it delivers extended tool life in high-heat cutting environments. The mill measures 0.0781 inches (5/64 inches) in cutting diameter with a 15/16 inch (0.9400 inch) length of cut and a 2.5 inch overall length. Three right-hand spiral flutes with a 30-degree helix angle promote efficient chip evacuation and smooth surface finishes. This tool is center-cutting, allowing direct plunge entry into workpieces without a pre-drilled hole.

This end mill suits general-purpose milling, slotting, and profiling on CNC machining centers and manual mills. It is well suited for ferrous metals, stainless steel, titanium, and other hard alloys where heat buildup is a common concern. The 1/8 inch shank diameter fits standard collet chucks and end mill holders commonly found in both shop and field machining setups. Machinists, tool-and-die makers, and production CNC operators are the primary users of this tool.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance in hard material cuts
• AlTiN coating reduces friction and resists heat, extending tool life in dry or high-speed machining
• 3 right-hand spiral flutes with 30-degree helix angle for effective chip clearance
• Center-cutting design allows direct plunge milling without pilot hole
• Right-hand cutting direction compatible with standard spindle rotation on most CNC and manual mills
• Mill diameter tolerance of +0.0000 / -0.0010 inches ensures consistent, predictable fit

Compatibility

Designed as a standard 1/8 inch shank square end mill compatible with ER collet chucks, end mill holders, and similar toolholding systems that accept 1/8 inch straight shanks on CNC machining centers and manual knee mills.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator following shop safety protocols. Ensure the spindle is fully stopped and the machine is in a locked-out state before changing tooling. Seat the shank fully into the collet or holder to the recommended engagement depth and torque the retention hardware per the toolholder manufacturer specifications. Do not exceed the tool manufacturer recommended speeds and feeds for the workpiece material and coating type.
