Accupro 314843 Square End Mill 1/2 in 3 Flute Solid Carbide

Product Description

The ACCUPRO 314843 is a 3-flute solid carbide square end mill designed for precision milling operations in metal cutting and machining applications. With a 1/2 inch cutting diameter, a 1-1/4 inch length of cut, and a 37-degree helix angle, it delivers efficient chip evacuation and stable cutting performance across a range of workpiece materials. The micrograin carbide substrate provides the hardness and edge retention required for demanding cuts. This tool is sold individually and is intended for use by machinists and CNC operators working in job shops, production environments, and toolrooms.

This end mill is suited for slotting, profiling, and peripheral milling in ferrous and non-ferrous materials. The 3-inch overall length and 1/2 inch shank diameter make it compatible with standard ER and side-lock toolholders commonly found on vertical machining centers and knee mills. The bright/uncoated finish makes it well-suited for materials where coated tools may cause adhesion or where re-sharpening is a priority. Right-hand cutting and right-hand flute direction are standard for conventional CNC spindle rotation.

Key Features

• Micrograin solid carbide construction for superior hardness and edge retention
• 37-degree helix angle promotes efficient chip evacuation and reduced cutting forces
• 3 flutes provide a balance of chip clearance and surface finish quality
• Center-cutting capable, allowing plunge entry into the workpiece
• Bright/uncoated finish suitable for non-ferrous metals and re-sharpenable applications
• Right-hand cut and right-hand spiral for use with standard CNC spindle rotation

Compatibility

Designed as a standard 1/2 inch shank square end mill for use in machining centers, CNC mills, and manual knee mills equipped with ER collet chucks, end mill holders, or side-lock toolholders accepting 1/2 inch shank tooling.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and all energy is locked out before changing tooling. Insert the shank fully into the toolholder to the recommended gauge line and tighten to the toolholder manufacturer's specification. Verify runout with a dial indicator before beginning any cut, as excessive runout accelerates tool wear and degrades surface finish.
