Accupro 12183414 Square End Mill 7/16 in 4 Flute Carbide

Product Description

The ACCUPRO 12183414 is a solid carbide square end mill designed for precision metal removal in milling operations. Built from micrograin carbide, it delivers tight dimensional control and edge stability across a range of ferrous and non-ferrous materials. The 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. With a 7/16 inch cutting diameter and a 1-3/8 inch length of cut, this tool handles slotting, profiling, and peripheral milling tasks. The extra-long 4 inch overall length provides extended reach into deep pockets and stepped features. Licensed machinists and CNC operators are the typical end users for this style of end mill.

This end mill suits vertical and horizontal CNC machining centers as well as manual knee mills where rigid toolholding is available. The centercutting geometry allows plunge entry, making it useful for interpolated pocket roughing without the need for a pre-drilled starter hole. The right-hand cut and right-hand spiral flute configuration is the standard setup for the majority of conventional and climb milling applications in production and job-shop environments.

Key Features

• Micrograin solid carbide construction for superior edge retention and dimensional accuracy
• 40-degree helix spiral flute for aggressive chip evacuation and reduced cutting forces
• 4-flute configuration balances material removal rate with surface finish quality
• Centercutting design enables direct plunge entry without a pilot hole
• Extra-long 4 inch overall length for deep-pocket and extended-reach milling
• Uncoated finish suitable for use with cutting fluid in a wide range of materials

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide square end mill for CNC machining centers and manual mills accepting a 7/16 inch straight shank.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Secure the shank fully within a collet, end mill holder, or shrink-fit toolholder to the minimum recommended engagement depth before torquing to the toolholder specification. Confirm spindle is fully stopped and machine is in an e-stop or locked-out state before changing tooling. Inspect the cutting edges and shank for chips or runout before each use.
