Accupro 14788351 Square End Mill 7/32 in 2 Flute Carbide

Product Description

The ACCUPRO 14788351 is a solid carbide square end mill designed for precision milling operations in metal, composites, and hard materials. With a 7/32 inch (0.2190 inch) mill diameter and a 2-flute helical configuration, this centercutting end mill delivers clean entry into material at plunge angles and produces accurate square-bottom slots and pockets. The 38-42 degree helix angle promotes efficient chip evacuation and smooth cutting action. A 1/4 inch cylindrical shank seats securely in standard collet chucks and end mill holders. Overall length is 2 inches, keeping the tool compact and rigid for reduced deflection in close-tolerance work.

This end mill is suited for slotting, profiling, and pocket milling in small-diameter applications on manual mills, CNC machining centers, and CNC routers. The solid carbide construction handles demanding cutting conditions and maintains edge sharpness longer than high-speed steel tooling, making it a practical choice for machinists and toolmakers working in production or job-shop environments.

Key Features

• Centercutting geometry allows direct plunge entry without a pre-drilled start hole
• Solid carbide construction for superior hardness and wear resistance compared to HSS
• 2-flute helical design promotes chip clearance in slotting and pocket operations
• 38-42 degree helix angle for smooth cutting action and reduced cutting forces
• Cylindrical 1/4 inch shank fits standard collet chucks and end mill holders
• Compact 2 inch overall length reduces overhang and minimizes deflection

Compatibility

Designed as a standard-shank replacement end mill compatible with any machine tool spindle or collet chuck accepting a 1/4 inch cylindrical shank, including ER collet systems and straight-bore end mill holders.

Installation Notes

Installation and tool changes must be performed with the machine fully powered down and the spindle at a complete stop. Seat the shank fully into the collet or holder and torque the retention nut according to the toolholder manufacturer specifications. Inspect cutting edges for chips or wear before each use and replace the tool if edge integrity is compromised. Follow applicable shop safety protocols and machine operator guidelines when setting tool length offsets and running first cuts at reduced feed rates.
