Accupro 14788354 Square End Mill 2 Flute 3/8 Inch Carbide

Product Description

The ACCUPRO 14788354 is a 2-flute, solid carbide square end mill designed for precision milling operations in metal, composites, and hard plastics. With a 3/8 inch (0.3750 inch) mill diameter and a 5/8 inch (0.6250 inch) length of cut, this tool delivers clean, accurate results in slotting, profiling, and peripheral milling applications. The helical flute geometry with a 38 to 42 degree helix angle promotes efficient chip evacuation and reduces cutting forces. Centercutting capability allows plunge entry directly into the workpiece without a pre-drilled pilot hole.

This end mill is suited for use in vertical and horizontal machining centers, CNC milling machines, and manual knee mills. It is appropriate for job shops, production environments, and toolroom applications where a reliable general-purpose solid carbide end mill is required. The cylindrical shank fits standard collet chucks and end mill holders sized for 3/8 inch tooling. Overall length is 2 inches, keeping overhang minimal for improved rigidity during aggressive cuts.

Key Features

• Centercutting design allows direct plunge milling without a pilot hole
• 38 to 42 degree helix angle promotes chip evacuation and smooth cutting action
• Solid carbide construction provides rigidity and wear resistance over high-speed tool steel
• Helical flute geometry reduces vibration and chatter during profiling passes
• Cylindrical shank compatible with standard 3/8 inch collets and end mill holders
• No chipbreaker — suited for finishing and semi-finishing passes requiring smooth surface finish

Compatibility

Designed as an OEM-style replacement solid carbide square end mill for use in any machine tool accepting a 3/8 inch cylindrical shank with standard collet or end mill holder tooling.

Installation Notes

Installation is performed by machinist or toolroom personnel. Secure the cylindrical shank in a clean, undamaged collet or end mill holder, torquing the retention mechanism per the machine tool manufacturer's specifications. Inspect the collet bore and shank for chips or contamination before seating. Confirm spindle runout is within acceptable limits before beginning the cut to preserve tool life and workpiece accuracy.
