Accupro 12179751 Square End Mill 5/8 in 3 Flute Carbide

Product Description

The ACCUPRO 12179751 is a solid carbide square end mill designed for precision milling operations in metal-cutting applications. Built from micrograin carbide stock, this single-end tool features a 5/8-inch cutting diameter, a 7/8-inch length of cut, and a 3-inch overall length. The AlTiN coating provides heat resistance and extends tool life in ferrous and high-temperature alloy cuts. Three spiral flutes at a 40-degree helix angle promote efficient chip evacuation and smooth surface finish. The centercutting geometry allows plunge entry as well as conventional peripheral milling. Licensed machinists, tool-and-die workers, and CNC operators are the primary users of this type of end mill.

This end mill is suited for stub-length milling work where rigidity and minimal deflection are priorities. The compact 7/8-inch length of cut keeps the tool stiff in the cut, making it appropriate for finishing passes and light roughing in steel, stainless, and similar materials. The right-hand cut and right-hand flute configuration is standard for conventional CNC machining center spindles. The 5/8-inch shank diameter matches common ER and side-lock toolholders used on vertical and horizontal milling centers.

Key Features

• Solid micrograin carbide construction for hardness and wear resistance
• AlTiN coating for elevated heat tolerance in ferrous material cutting
• 40-degree spiral helix promotes chip lift and reduces cutting forces
• Centercutting design enables plunge milling without a pre-drilled entry hole
• Stub-length geometry maximizes rigidity and minimizes tool deflection
• Right-hand cut and right-hand flute — standard configuration for CNC mill spindles

Compatibility

Designed as a standard stub-length square end mill compatible with 5/8-inch ER collet chucks, Weldon side-lock holders, and shrink-fit toolholders sized for 5/8-inch shank diameters on CNC vertical or horizontal machining centers.

Installation Notes

Installation is performed by a machinist or CNC setup technician. The spindle must be at a full stop and the machine in an estop or lockout state before loading or changing tooling. Seat the shank fully into the toolholder and verify runout with a dial indicator before cutting. Follow the toolholder manufacturer torque specifications for collet nuts and set screws — do not over-torque carbide shanks.
