Accupro 316132 Square End Mill 1 in 5 Flute Solid Carbide Zrn

Product Description

The ACCUPRO 316132 is a solid carbide square end mill designed for precision milling operations in metalworking and machining environments. It features a 1-inch mill diameter, a 2-inch length of cut, and a 5-inch overall length with a 1-inch shank diameter. The five-flute, spiral geometry with a 37-degree helix angle promotes efficient chip evacuation and smooth cutting action. A zirconium nitride (ZrN) finish increases surface hardness and reduces friction at the cutting edge. Micrograin carbide construction delivers consistent edge integrity under high-feed conditions. This end mill is centercutting, allowing plunge entry directly into workpiece material.

This end mill is suited for milling ferrous and non-ferrous metals in CNC machining centers and manual mills. The right-hand cut and right-hand flute configuration matches standard spindle setups. The five-flute design makes it a strong choice for finishing passes and medium-load profiling where surface finish quality matters. Typical users include machinist shops, tool and die operations, and production machining facilities running steel, stainless, or aluminum stock.

Key Features

• Solid micrograin carbide construction for consistent edge life and rigidity
• ZrN coating reduces heat buildup and extends tool life in ferrous applications
• 37-degree helix angle with spiral flute for effective chip evacuation
• Centercutting geometry allows direct plunge milling without pre-drilling
• Five-flute configuration supports high feed rates and fine surface finishes
• Mill diameter tolerance of plus 0.000 / minus 0.002 inches for close-tolerance work

Compatibility

Designed as a direct-fit tooling solution for CNC machining centers and manual milling machines accepting a 1-inch straight shank with standard ER or side-lock toolholders. No specific model compatibility was stated in the product data.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully stopped and the machine is powered down before loading or removing the end mill. Use a calibrated toolholder rated for the 1-inch shank diameter and verify runout with a dial indicator before cutting. Consult the machine manufacturer and applicable OSHA machining guidelines for proper speeds, feeds, and clamping torque.
