Accupro 12182742 Square End Mill 5/32 in 4 Flute Carbide

Product Description

The ACCUPRO 12182742 is a solid carbide square end mill designed for precision milling operations in metal, composites, and engineering plastics. Built from micrograin carbide, this tool delivers a 5/32 inch (0.1563 inch decimal) cutting diameter with a 3/8 inch length of cut. The 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. At 2 inches overall length with a stub-length profile, it suits applications where rigidity and minimal deflection are priorities. Machinists and tool-and-die professionals install this end mill in CNC machining centers and manual knee mills for slotting, profiling, and light contouring work.

This end mill fits residential and industrial machining environments where tight tolerances are required. The stub-length design provides increased rigidity for demanding cuts in harder materials. The 3/16 inch shank diameter fits standard collets and end mill holders common to most CNC and manual milling setups. Its uncoated finish makes it a practical general-purpose choice, and centercutting capability allows direct plunge entry without a pre-drilled pilot hole.

Key Features

• Micrograin solid carbide construction for extended tool life in demanding materials
• 40-degree helix angle for efficient chip evacuation and reduced cutting forces
• 4-flute configuration balances material removal rate with finish quality
• Centercutting design allows direct plunge milling without pilot drilling
• Stub-length profile maximizes rigidity and minimizes deflection
• Right-hand cut and right-hand flute for standard spindle operation

Compatibility

Designed as a direct-fit replacement for standard 3/16 inch shank square end mill applications in CNC machining centers and manual mills using compatible collets or end mill holders.

Installation Notes

Installation should be performed by a qualified machinist following shop safety protocols. Ensure the machine spindle is fully stopped and locked out before inserting or removing the end mill. Seat the shank fully into the collet or tool holder and torque the retention mechanism to the machine manufacturer specification. Verify runout with a dial indicator before beginning production cuts.
