Accupro 14777961 Square End Mill 5/8 in 5 Flute Carbide

Product Description

The ACCUPRO 14777961 is a solid carbide square end mill designed for precision milling operations in metal cutting and machining applications. It features a 5/8-inch mill diameter with a 1-7/8-inch length of cut and five flutes, making it well-suited for higher feed rates and improved chip evacuation compared to four-flute tooling. The 36-degree right-hand helix angle promotes smooth cutting action and reduced vibration. Built from micrograin solid carbide, this end mill delivers the rigidity and wear resistance required for demanding cutting conditions. It ships in a bright, uncoated finish. Licensed machinists and CNC operators are the primary users of this tooling.

This end mill is suited for milling operations on ferrous and non-ferrous materials where a square shoulder profile is required. The AL-5 series designation indicates it is optimized for demanding cutting environments. Its 4-inch overall length and straight cylindrical shank make it compatible with standard collet chucks and end mill holders commonly found in vertical machining centers and manual knee mills. The variable index geometry and chipbreaker features help manage chip load and reduce chatter during long-reach or aggressive milling passes.

Key Features

• 5 flutes with variable index geometry for reduced chatter and improved surface finish
• Chipbreaker design aids chip evacuation and reduces cutting forces
• 36-degree right-hand spiral flute promotes efficient chip flow
• Micrograin solid carbide construction for superior wear resistance and edge retention
• Bright/uncoated finish suitable for use with or without cutting fluid
• Straight cylindrical shank fits standard collet and end mill holder tooling systems

Compatibility

Designed for use in standard end mill holders and collet chucks accepting a 5/8-inch straight cylindrical shank, common on vertical machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully powered down and locked out before loading or unloading tooling. Verify that the shank is seated to the recommended engagement depth in the holder and that all set screws or collet nuts are properly torqued per the toolholder manufacturer specifications. Inspect the cutting edges for chips or damage before each use.
