Accupro 14788337 Square End Mill 7/16 Inch 2 Flute Carbide

Product Description

The ACCUPRO 14788337 is a solid carbide square end mill designed for precision milling operations in metal, composites, and engineering plastics. It features a 7/16 inch (0.4380 inch) mill diameter with a matching 7/16 inch cylindrical shank, two helical flutes, and a 1 inch length of cut. The centercutting geometry allows for direct plunge entry into the workpiece without pre-drilling, making it suitable for slot milling, profiling, and pocketing operations. Solid carbide construction provides rigidity and wear resistance beyond high-speed steel alternatives. This tool is installed and operated by machinists and CNC operators in job shop, production, and tool room environments.

This end mill is suited for use in vertical machining centers, CNC knee mills, and manual bridgeport-style mills. The 7/16 inch shank fits standard ER collet chucks, milling chucks, and Weldon-style side-lock holders. With a 2-3/4 inch overall length and no extended reach, it is best applied in close-clearance setups where rigidity is a priority. It is appropriate for finishing and semi-finishing passes on ferrous and non-ferrous workpieces where tight tolerances and consistent surface finish are required.

Key Features

• Solid carbide construction for superior hardness and thermal resistance compared to HSS
• Centercutting design permits direct plunge milling without pilot holes
• Two helical flutes promote chip evacuation and reduce cutting forces in slotting
• Cylindrical shank at 0.4380 inches matches mill diameter for balanced tool holding
• 1 inch length of cut supports full-depth slotting and profiling passes
• No chipbreaker geometry — suited for finishing applications requiring smooth floor finish

Compatibility

Designed as an OEM-style solid carbide square end mill compatible with standard 7/16 inch collet chucks, milling chucks, and side-lock holders used in CNC and manual milling machines.

Installation Notes

Installation is performed by a machinist or CNC operator. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Secure the shank firmly in the tool holder to the appropriate clamping torque per the holder manufacturer specification, and verify runout with a dial indicator before beginning a cut. Carbide end mills are brittle — avoid dropping or contacting hard surfaces during handling.
