Accupro 12178614 Square End Mill 5/8 in 3 Flute Solid Carbide

Product Description

The ACCUPRO 12178614 is a solid carbide square end mill designed for precision milling operations in metal fabrication and machining environments. It features a 5/8-inch cutting diameter, a 2-1/2-inch length of cut, and a 6-inch overall length, making it well suited for applications that require extended reach without sacrificing rigidity. The three-flute, spiral geometry with a 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. Manufactured from micrograin solid carbide, this end mill offers the hardness and edge retention needed for demanding ferrous and non-ferrous machining tasks. It ships uncoated and is ready for immediate use.

This end mill is intended for use in CNC machining centers, knee mills, and manual vertical mills where a right-hand cut, right-hand flute configuration is standard. The centercutting capability allows it to plunge directly into workpieces, enabling slotting, profiling, and pocket milling in a single tool. The long-length classification makes it appropriate for deep-pocket work and tall-workpiece setups where standard-length tools cannot reach. It is typically used by machinists and tool-and-die professionals working in job shops, production facilities, and tool rooms.

Key Features

• Micrograin solid carbide construction for superior hardness and edge retention
• 40-degree helix angle promotes efficient chip evacuation in deep cuts
• Centercutting design enables direct plunge entry into material
• Three-flute spiral geometry balances material removal rate and finish quality
• Long-length classification supports deep-pocket and tall-workpiece applications
• Right-hand cut and right-hand flute for standard CNC and manual mill setups

Compatibility

Designed as a direct-fit tooling solution for standard 5/8-inch collets, ER collet chucks, end mill holders, and milling machine spindles accepting a 5/8-inch shank diameter. Compatible with CNC machining centers and manual vertical mills configured for right-hand tooling.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's spindle and collet torque guidelines. Ensure the machine spindle is fully stopped and the control is in an e-stop or locked-out state before inserting or removing the tool. Verify shank seating depth meets the holder manufacturer's minimum engagement recommendation. Confirm runout with a dial indicator before taking the first cut, as excessive runout accelerates edge wear on carbide tooling.
