Accupro 12181698 Square End Mill 9/16 in 2 Flute Carbide

Product Description

The ACCUPRO 12181698 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. Built from micrograin solid carbide, it delivers the rigidity and edge retention needed for demanding cuts in ferrous and non-ferrous materials. The 9/16 inch cutting diameter pairs with a 7/8 inch length of cut and a 40-degree helix angle, promoting efficient chip evacuation and reduced cutting forces. The uncoated finish suits applications where coating compatibility or re-sharpening cost is a factor. Licensed machinists and CNC operators working in job shops, toolrooms, and production environments are the primary users of this end mill.

This end mill fits stub-length milling operations where a shorter, stiffer profile is preferred to minimize deflection. It is suited for side milling, slotting, and profiling in a wide range of materials. The right-hand cut and right-hand spiral flute configuration is standard for conventional CNC machining centers and manual knee mills. Centercutting geometry allows plunge entry directly into the workpiece, eliminating the need for a pre-drilled pilot hole in many setups.

Key Features

• Micrograin solid carbide construction for high hardness and wear resistance
• 40-degree helix angle promotes efficient chip evacuation and smooth cutting action
• Centercutting design enables direct plunge milling without a pilot hole
• 2-flute configuration supports slotting and pocketing in a wide range of materials
• Right-hand cut and right-hand flute direction for standard spindle compatibility
• Stub length profile reduces deflection in high-precision or tight-tolerance cuts

Compatibility

Designed as a standard stub-length square end mill compatible with CNC machining centers, vertical mills, and similar equipment using ER or straight-shank toolholders sized for a 9/16 inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines for toolholder torque and runout tolerances. Verify spindle and toolholder are clean and free of debris before seating the shank. Ensure the machine is fully stopped and locked out before changing tooling. Confirm the correct cutting direction matches spindle rotation before initiating a cut.
