Accupro 14788434 Square End Mill 3 Flute 3/8 Inch Carbide

Product Description

The ACCUPRO 14788434 is a 3-flute solid carbide square end mill designed for material removal and profile milling in metalworking and machining applications. With a 3/8 inch (0.3750 inches) mill diameter and a 1-3/4 inch (1.7500 inches) length of cut, this end mill delivers consistent performance in both slotting and peripheral milling operations. The solid carbide construction provides rigidity and heat resistance, making it well suited for harder workpiece materials. Centercutting capability allows the tool to plunge directly into material. Installed by machinists and tool-and-die professionals, this end mill fits standard CNC mills and manual knee mills accepting a 3/8 inch cylindrical shank.

This end mill is used in production and job-shop machining environments for cutting ferrous and non-ferrous metals, plastics, and composites. Its helical flute geometry promotes chip evacuation and smooth cutting action during side milling, slotting, and contour operations. The 4 inch overall length provides adequate reach for standard workpiece setups without sacrificing rigidity. It is a direct-fit replacement for worn or damaged tooling in shops running 3/8 inch shank toolholders.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding cuts
• 3 helical flutes for efficient chip evacuation during slotting and profiling
• Centercutting design allows direct plunge entry into the workpiece
• 3/8 inch cylindrical shank fits standard collets and end mill holders
• 1-3/4 inch length of cut suits moderate-depth milling applications
• 4 inch overall length provides a stable reach for typical CNC and manual mill setups

Compatibility

Designed as an OEM-style replacement for solid carbide square end mills requiring a 3/8 inch cylindrical shank and 3/8 inch mill diameter in standard end mill holders and collet chucks.

Installation Notes

Installation is performed by a qualified machinist. Ensure the machine spindle is fully powered down and locked out before changing tooling. Seat the shank fully into the collet or end mill holder and torque the retention mechanism per the toolholder manufacturer's specifications. Inspect the cutting edges for chips or wear before each use and replace the end mill if edge damage is present.
