Accupro 314496 Square End Mill 5/32 in 3 Flute Solid Carbide

Product Description

The ACCUPRO 314496 is a solid carbide square end mill designed for precision milling operations in metal, composites, and other hard materials. With a 5/32 inch (0.1563 inch) cutting diameter and a 9/16 inch length of cut, this stub-length tool offers rigidity in tight setups where deflection is a concern. Three right-hand flutes with a 37-degree helix angle promote efficient chip evacuation and smooth cutting action. Micrograin carbide construction delivers hardness and wear resistance suited to high-feed applications. The bright, uncoated finish makes this tool a straightforward choice when coating compatibility with a specific material or coolant is a factor.

This end mill is used in CNC machining centers, knee mills, and manual milling machines for slotting, profiling, and peripheral milling. The stub-length geometry reduces overhang and increases rigidity, making it well suited for shallow-depth operations where chatter control matters. The 3/16 inch shank diameter fits standard collets and end mill holders commonly found in light-duty and mid-range machine tool setups. It is a single-end tool intended for professional machine shop use by machinists and tool-and-die tradespeople.

Key Features

• Micrograin solid carbide construction for hardness and edge retention
• 3 right-hand flutes with 37-degree helix for efficient chip evacuation
• Stub-length design reduces deflection and improves rigidity
• Centercutting geometry allows plunge entry
• Bright/uncoated finish compatible with a wide range of materials and coolants
• Mill diameter tolerance of +0.000/-0.005 inch for consistent fit and finish

Compatibility

Designed as an OEM-style replacement or direct-fit solid carbide square end mill for use in standard 3/16 inch collets and end mill holders on CNC and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist following machine tool manufacturer guidelines. Ensure the spindle is fully stopped and locked out before changing tooling. Seat the shank fully in the collet or holder to the recommended engagement depth and torque the retention hardware to the machine tool manufacturer specification. Inspect runout after installation before beginning any cut.
