Accupro 14788330 Square End Mill 11/64 in 2 Flute Carbide

Product Description

The ACCUPRO 14788330 is a solid carbide square end mill designed for precision milling operations in metal, composite, and engineering-grade plastic materials. It features two helical flutes with a helix angle of 38 to 42 degrees, promoting efficient chip evacuation and smooth cutting action. The centercutting geometry allows the tool to plunge directly into a workpiece, expanding its usefulness beyond peripheral milling. With a mill diameter of 0.172 inches (11/64 inch) and a cylindrical shank diameter of 0.188 inches (3/16 inch), this end mill fits standard collet chucks and milling tool holders used on CNC machining centers and manual knee mills alike.

This end mill is well suited for finish milling, slotting, and light profiling passes in small-feature work where precise diameter control is critical. The 0.625-inch (5/8 inch) length of cut accommodates shallow-to-moderate pocket depths without excessive tool overhang. The 2-inch overall length keeps the tool rigid at this diameter, reducing deflection during cuts. Machinists working on instrument components, mold details, medical device parts, and aerospace brackets will find this size appropriate for fine detail work requiring tight tolerances.

Key Features

• Solid carbide construction for superior hardness and wear resistance compared to high-speed steel
• Centercutting design allows direct plunge entry into workpiece material
• Two helical flutes with 38 to 42 degree helix angle for effective chip removal
• Cylindrical shank compatible with standard collet and end mill holder tooling
• 0.172-inch mill diameter (11/64 inch) suited for small-feature and detail milling
• No chipbreaker geometry, providing a clean straight flute profile for finishing cuts

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide end mill for CNC machining centers, manual vertical mills, and similar equipment using standard collet systems accepting a 3/16 inch cylindrical shank.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the spindle is fully powered down and the machine is locked out before changing tooling. Seat the shank fully into the collet or end mill holder to the recommended engagement depth before tightening. Inspect the flute edges and shank for chipping or runout before use, as solid carbide tools at this diameter are sensitive to improper clamping and side loads.
