Accupro 12185432 7/16 Inch 4-flute Carbide Square End Mill

Product Description

The ACCUPRO 12185432 is a solid carbide square end mill designed for both roughing and finishing operations in a single tool. It features a 7/16-inch cutting diameter, four flutes, and a 40-degree helix angle that promotes efficient chip evacuation and smooth cutting action. The chipbreaker geometry reduces cutting forces during aggressive material removal, making this tool suitable for high-feed roughing passes as well as finish cuts. It ships uncoated and is manufactured from solid carbide for rigidity and wear resistance. Machinists and toolroom professionals install this end mill in CNC machining centers and manual knee mills for ferrous and non-ferrous stock removal.

This end mill is well suited for production and toolroom environments where a single tool must handle both roughing and semi-finishing passes without a tool change. The long-length configuration, with a 2-inch length of cut and 4-inch overall length, allows access to deeper features such as pockets, slots, and stepped profiles. The right-hand cutting direction and right-hand flute spiral are standard for conventional CNC spindle rotation. Single-end construction means the tool is replaced rather than flipped when the cutting edge is worn.

Key Features

• 7/16-inch cutting diameter with matching 7/16-inch shank for direct collet or end mill holder mounting
• 4-flute, right-hand spiral geometry with 40-degree helix angle for balanced chip flow and surface finish
• Chipbreaker profile reduces cutting forces and heat buildup during roughing passes
• 2-inch length of cut and 4-inch overall length provide reach for deep pockets and slots
• Solid carbide construction delivers rigidity and edge retention superior to HSS in harder workpiece materials
• Uncoated finish allows easy inspection of edge wear and suits applications where coating adhesion is a concern

Compatibility

Designed as a direct-fit replacement or standard toolroom addition for any CNC machining center or manual mill accepting a 7/16-inch straight shank end mill via ER collet, end mill holder, or set-screw holder.

Installation Notes

Installation is performed by a machinist or toolroom technician. Ensure the spindle is powered down and locked before seating or removing the tool from its holder. Use a calibrated torque wrench on set-screw holders and confirm runout with a dial indicator before cutting to extend tool life and maintain dimensional accuracy. Do not exceed the tool manufacturer's recommended depth-of-cut and feed-rate parameters for the workpiece material.
