Accupro 12182088 Square End Mill 9/16 in 3 Flute Carbide

Product Description

The ACCUPRO 12182088 is a solid carbide square end mill designed for precision milling operations in metalworking and machining applications. With a 9/16 inch (0.5625 inch) mill diameter, a 1-1/4 inch length of cut, and a 3-1/2 inch overall length, this tool is built for rigidity and accurate material removal. The 40-degree helix angle and spiral flute geometry promote efficient chip evacuation and reduce cutting forces. Micrograin carbide construction provides the hardness and edge retention needed for demanding ferrous and non-ferrous workpiece materials. Three flutes deliver a balance between chip clearance and surface finish. This is a single-end, uncoated tool with right-hand cut and right-hand flute direction.

This end mill is suited for general-purpose milling tasks including slotting, profiling, and peripheral milling on CNC machining centers and manual mills. The centercutting design allows for direct plunge entry into the workpiece without a pre-drilled pilot hole, making it versatile across a range of setups. The regular length classification and matched shank and cutter diameter simplify tool selection in standard toolholders. It is intended for use by machinists and CNC operators working in job shops, production environments, and tool rooms where consistent dimensional accuracy is required.

Key Features

• Solid micrograin carbide construction for hardness and long edge life
• 40-degree helix angle promotes aggressive chip evacuation and smooth cutting action
• Centercutting geometry allows direct plunge milling without pre-drilling
• Right-hand cut and right-hand flute direction for standard spindle rotation
• Matched 9/16 inch shank and cutter diameter for straightforward toolholder setup
• Uncoated finish suitable for use with cutting fluids across a variety of materials

Compatibility

Designed as a standard-shank square end mill compatible with ER collet chucks, end mill holders, and milling chucks accepting a 9/16 inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and the tool is secured with adequate shank engagement in the toolholder before operation. Follow the toolholder manufacturer torque recommendations when tightening collet nuts or set screws. Verify runout after installation to protect edge life and dimensional accuracy.
