Accupro 12181735 Square End Mill 5/8 in 2 Flute Carbide

Product Description

The ACCUPRO 12181735 is a solid carbide square end mill designed for precision milling operations in ferrous and non-ferrous materials. With a 0.625-inch mill diameter and a 2.125-inch length of cut, this tool provides extended reach for slotting, profiling, and pocketing in deeper cavities. The TiCN (titanium carbonitride) coating improves wear resistance and surface hardness compared to uncoated carbide. Micrograin carbide construction contributes to edge retention under demanding cutting conditions. This tool is used by machinists and CNC operators in job shop and production environments where long-reach capability is required without sacrificing rigidity.

This end mill is suited for long-reach milling applications where standard-length tools cannot access the full depth of a feature. The 40-degree helix angle promotes efficient chip evacuation and reduced cutting forces, making it appropriate for both roughing passes and finish cuts in steel, stainless, cast iron, and hardened materials within the tool's rated capacity. Centercutting geometry allows plunge entry directly into the workpiece. Right-hand cut and right-hand spiral flute configuration is standard for conventional CNC machining center spindle rotation.

Key Features

• Solid micrograin carbide construction for edge retention in demanding materials
• TiCN coating for improved wear resistance and tool life
• 40-degree helix angle for efficient chip evacuation and reduced cutting forces
• Centercutting design allows direct plunge milling without pre-drilling
• Long-reach length type with 2.125-inch length of cut in a 4.625-inch overall length tool
• Spiral flute, right-hand cut, right-hand flute — standard CNC spindle compatible

Compatibility

Designed as an OEM-style solid carbide square end mill for use in standard 5/8-inch collet or end mill holders on CNC machining centers and manual knee mills equipped for right-hand rotation.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before inserting or removing the tool. Seat the shank fully into the holder to the recommended engagement depth per the toolholder manufacturer's specification. Verify runout with a dial indicator after installation before beginning a cut, particularly for finish milling operations.
