Accupro 12469980 Square End Mill 1/4 in 4 Flute Carbide

Product Description

The ACCUPRO 12469980 is a solid carbide square end mill designed for precision milling operations in metal, composites, and other hard materials. The 1/4 inch diameter cutting head features 4 right-hand spiral flutes with a 30-degree helix angle, providing efficient chip evacuation and smooth cutting action. The micrograin carbide construction delivers hardness and wear resistance suited to demanding machining environments. This is a single-end, center-cutting tool, meaning it can be used for plunge cuts as well as peripheral and slot milling. Licensed machinists and tool-and-die professionals are the primary installers of this tooling.

This end mill fits applications requiring a 1/4 inch shank in standard CNC machining centers, manual milling machines, and compatible tool holders. With a 1-1/2 inch length of cut and 4 inch overall length, it suits moderate-depth slot milling, profiling, and contouring work. The bright, uncoated finish makes it a general-purpose choice where coating is not required by the material or process specification. It is well suited for job shop environments, maintenance machining, and prototype work where a reliable, uncoated carbide tool is preferred.

Key Features

• Solid micrograin carbide construction for hardness and edge retention
• 4 right-hand spiral flutes with 30-degree helix angle for efficient chip removal
• Center-cutting geometry supports plunge milling entry
• Bright, uncoated finish for general-purpose material compatibility
• 1/4 inch shank with tight tolerance (-0.0001 to -0.0003 inches) for secure tool holder fit
• Single-end design with 1-1/2 inch length of cut suitable for moderate-depth passes

Compatibility

Designed for use with standard 1/4 inch collets, end mill holders, and compatible CNC or manual milling machine spindles accepting a 1/4 inch straight shank. Series ASQSC4-CC-30H.

Installation Notes

Installation should be performed by a qualified machinist following standard tooling safety procedures. Ensure the machine spindle is fully stopped and locked out before inserting or removing the end mill. Use a properly sized collet or end mill holder torqued to the machine manufacturer's specification. Inspect the cutting edges for chips or wear before each use and replace tooling that shows edge degradation to avoid workpiece damage or tool breakage.
