Accupro 314434 Square End Mill 1/8 in 3 Flute Carbide

Product Description

The ACCUPRO 314434 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. Built from micrograin carbide, it offers a 1/8 inch cutting diameter with a 1/4 inch length of cut and a 37-degree helix angle. The three-flute spiral configuration balances chip evacuation with surface finish quality, making it well suited for slotting, profiling, and contouring cuts. The bright/uncoated finish is appropriate for use in a broad range of workpiece materials. At 1-1/2 inches overall length, this is a stub-length tool intended for rigidity in close-clearance setups.

This end mill fits standard CNC machining centers, knee mills, and manual milling machines with a 1/8 inch collet or toolholder. The stub-length design reduces deflection in short-reach cuts, making it a practical choice for high-precision work in die and mold, prototype, and production environments. Right-hand cutting and right-hand flute direction are standard for conventional spindle rotation. The centercutting geometry allows direct plunge entry into the workpiece without a pre-drilled hole.

Key Features

• Micrograin solid carbide construction for wear resistance and edge retention
• 37-degree helix angle promotes smooth chip flow and reduced cutting forces
• Three-flute spiral design balances material removal rate with finish quality
• Centercutting capable — supports direct plunge milling
• Stub-length OAL of 1-1/2 inches maximizes rigidity in tight setups
• Bright/uncoated finish compatible with a wide range of base materials

Compatibility

Designed for use in any 1/8 inch collet chuck, ER collet system, or precision toolholder on CNC or manual milling equipment. No specific machine or system compatibility was stated in the product data.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the shank fully into the collet to the recommended engagement depth and torque the collet nut to the toolholder manufacturer specification. Verify runout with a dial indicator before beginning the cut, as excessive runout will accelerate wear on a tool of this diameter.
