Accupro 314863 Square End Mill 1/2in 3 Flute Carbide

Product Description

The ACCUPRO 314863 is a solid carbide square end mill designed for precision milling operations in metalworking and machining applications. With a 1/2 inch cutting diameter and 1-1/2 inch length of cut, it handles slotting, profiling, and peripheral milling in a single-end configuration. The 3-flute geometry with a 37-degree right-hand spiral helix balances chip evacuation and cutting efficiency in a range of ferrous and non-ferrous materials. Micrograin carbide construction provides edge retention and resistance to chipping under demanding cutting conditions. The bright uncoated finish suits general-purpose machining where coating is not required or preferred.

This end mill fits standard CNC machining centers, vertical mills, and manual knee mills equipped with an R8, CAT, BT, or collet-style toolholder accepting a 1/2 inch shank. It is suited for production shops, tool rooms, and job shops running steel, aluminum, cast iron, and similar materials where a 3-flute solid carbide tool is the specified choice. The 4 inch overall length accommodates standard reach requirements without excessive overhang.

Key Features

• 3-flute right-hand spiral design with 37-degree helix angle for balanced chip flow
• Micrograin solid carbide substrate for superior hardness and edge retention
• Center-cutting capable for plunge entry and ramp milling
• Bright uncoated finish compatible with a wide range of base materials
• 1/2 inch shank with tight diameter tolerance for secure toolholder fit
• Single-end configuration with 4 inch overall length for standard-reach applications

Compatibility

Designed as an OEM-style replacement and standard tooling option for machining setups requiring a 1/2 inch shank, 3-flute solid carbide square end mill with a 1-1/2 inch length of cut.

Installation Notes

Installation is performed by a machinist or CNC setup technician using a collet, end mill holder, or set-screw toolholder rated for the 1/2 inch shank diameter. Ensure the machine spindle is fully stopped and locked before inserting or removing tooling. Apply the appropriate insertion depth per toolholder manufacturer guidelines to maximize rigidity and minimize runout. Verify shank clamping torque per toolholder specifications before commencing cuts.
