Accupro 12182451 Square End Mill 1/4 Inch 4 Flute Carbide

Product Description

The ACCUPRO 12182451 is a solid carbide square end mill designed for precision milling in ferrous and non-ferrous materials. With a 1/4 inch cutting diameter, a 3/4 inch length of cut, and a 4-flute spiral configuration at a 40-degree helix angle, this tool delivers efficient chip evacuation and clean edge finishes. Micrograin carbide construction provides edge retention and resistance to wear in demanding cutting environments. It is a single-end, right-hand cut and right-hand flute tool with centercutting capability, making it suitable for plunging as well as peripheral milling. Machinists and tool-and-die professionals are the primary users.

This end mill is suited for slot milling, profiling, and contour work on CNC machining centers and manual mills. Its regular length configuration and 2-1/2 inch overall length make it practical for standard-depth cavity and pocket work. The uncoated finish is appropriate for applications where a coated tool is not required or where re-sharpening is preferred. It is commonly used in job shops, toolrooms, and production environments working with aluminum, mild steel, brass, and similar materials.

Key Features

• Solid micrograin carbide construction for superior edge retention
• 4-flute spiral design with 40-degree helix angle for efficient chip flow
• Centercutting geometry allows direct plunge entry
• Right-hand cut and right-hand flute configuration
• Uncoated finish suitable for re-sharpening and general-purpose use
• Tight mill diameter tolerance of +0.000 / -0.002 inches for accurate fitment

Compatibility

Designed as a standard 1/4 inch shank square end mill compatible with CNC machining centers, knee mills, and manual milling machines accepting a 1/4 inch collet or tool holder.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's torque and runout specifications for collet systems. Ensure the machine spindle is fully stopped and locked out before changing tooling. Verify collet size matches the 1/4 inch shank diameter before seating the tool. Confirm tool stick-out does not exceed the minimum recommended grip length to avoid deflection or tool pull-out during cutting.
