Accupro 12183715 Square End Mill 7/16 in 4 Flute Carbide

Product Description

The ACCUPRO 12183715 is a solid carbide square end mill built for demanding milling operations in ferrous and non-ferrous materials. It features a 7/16-inch cutting diameter, a 1-1/2-inch length of cut, and a 6-inch overall length, placing it in the extra-long category for applications requiring extended reach. The 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. A TiCN coating adds surface hardness and lubricity, extending tool life in abrasive or high-temperature cutting conditions. Micrograin carbide construction provides the rigidity and edge retention needed for finish and semi-finish milling passes.

This end mill is suited for slot milling, profiling, and peripheral milling operations on CNC machining centers and manual knee mills. The extra-long overall length makes it appropriate for deep-pocket work or setups where standard-length tools cannot reach the workpiece. It is used by machinists in job shops, production facilities, and tool-and-die operations. Right-hand cut and right-hand spiral flute geometry are standard for conventional CNC spindle rotation. The centercutting design allows plunge entry directly into the material without a pre-drilled hole.

Key Features

• Solid micrograin carbide construction for edge retention in demanding cuts
• TiCN coating for increased surface hardness and reduced tool wear
• 40-degree helix angle promotes chip flow and reduces cutting forces
• Centercutting geometry allows direct plunge milling
• Extra-long 6-inch OAL for deep-pocket and extended-reach setups
• Right-hand cut, right-hand flute for standard CNC spindle compatibility

Compatibility

Designed as a direct-fit tool for any spindle or collet system accepting a 7/16-inch shank diameter, including ER, TG, and straight-bore collet chucks standard on CNC machining centers and manual knee mills.

Installation Notes

Install and remove end mills only with the spindle fully stopped and machine power off or in E-stop. Use a properly sized collet or tool holder matching the 7/16-inch shank diameter and torque the drawbar or collet nut to the tool-holder manufacturer's specification. Inspect the shank and collet bore for chips or debris before seating the tool. Follow shop safety protocols and applicable OSHA machine-guarding requirements during tool changes.
