Accupro 314836 Square End Mill 1/2in 3 Flute Carbide Zrn

Product Description

The ACCUPRO 314836 is a solid carbide square end mill designed for precision milling operations in metal fabrication and machining environments. It features a 1/2 inch diameter cutting profile with a 3/4 inch length of cut and a 37-degree helix angle, which promotes efficient chip evacuation and reduces cutting forces during operation. The ZrN (zirconium nitride) coating improves surface hardness and heat resistance, extending tool life in demanding materials. This end mill is a single-end tool with three flutes and is center-cutting capable, making it suitable for plunge entry as well as peripheral and slot milling. It is installed and used by machinists and tool-and-die professionals working on CNC mills and manual milling machines.

This end mill is suited for ferrous and non-ferrous material removal in both production and job-shop environments. The micrograin carbide substrate and right-hand cutting and flute direction make it a standard choice for conventional and climb milling passes in aluminum, steel, and similar workpiece materials. The 1/2 inch shank diameter fits standard ER and end mill holders commonly found in vertical machining centers and knee mills. No specific compatible machine models are named in the available data.

Key Features

• 1/2 inch cutting diameter with a 3/4 inch length of cut for general milling applications
• 3 flute, right-hand spiral design for efficient chip removal and good surface finish
• 37-degree helix angle reduces cutting forces and improves chip flow
• ZrN coating increases wear resistance and thermal stability
• Center-cutting capable - supports direct plunge entry into workpiece material
• Micrograin solid carbide construction for rigidity and edge retention

Compatibility

Designed as a standard replacement or stock tooling option for 1/2 inch end mill holders and collet chucks accepting a 1/2 inch shank diameter in CNC and manual milling setups.

Installation Notes

End mills of this type are installed by machinists using an appropriate end mill holder or collet chuck torqued to the machine spindle manufacturer's specification. Ensure the machine spindle is fully powered down and locked out before changing tooling. Verify shank seating depth and runout with a dial indicator before commencing cuts. Handle carbide tooling carefully to avoid edge chipping from impact with other metal surfaces.
