Accupro 14788505 Square End Mill 4 Flute Solid Carbide

Product Description

The ACCUPRO 14788505 is a solid carbide square end mill designed for precision milling operations in metal, composite, and engineering plastic applications. Built with four helical flutes and a centercutting geometry, this tool is capable of both peripheral and plunge cutting. The 2mm mill diameter pairs with a 3mm cylindrical shank, giving machinists flexibility when working in tight-tolerance bores or confined pockets. A helix angle in the 29 to 31 degree range promotes efficient chip evacuation and smooth cutting action. At 38mm overall length with a 4mm length of cut, this end mill is suited for finish passes and detail work where a compact, rigid tool is required.

This end mill is used in CNC machining centers, manual knee mills, and benchtop mills where small-diameter, high-precision cutting is needed. It is a practical choice for tool and die shops, mold makers, and production machinists working with close-tolerance features in aluminum, brass, steel, and similar machinable materials. The solid carbide construction maintains edge integrity at higher spindle speeds compared to high-speed steel alternatives.

Key Features

• Solid carbide construction for rigidity and edge retention at elevated cutting speeds
• Four helical flutes for balanced chip load and smooth surface finish
• Centercutting design allows direct plunge entry into workpiece material
• Helix angle of 29 to 31 degrees promotes effective chip evacuation
• Cylindrical shank compatible with standard collet and end mill holder systems
• Compact 2mm mill diameter suited for fine detail and tight-pocket milling

Compatibility

Designed as an OEM-style replacement solid carbide square end mill for use in standard collet chucks and end mill holders accepting a 3mm cylindrical shank.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Secure the shank fully within the collet or end mill holder to the manufacturer-recommended engagement depth before tightening. Verify spindle runout after tooling is seated, as excessive runout will accelerate edge wear on small-diameter carbide tools. Always confirm the machine spindle is fully stopped and the control is in a safe state before changing tooling.
