Accupro 12181905 Square End Mill 9/64 in 3 Flute Carbide

Product Description

The ACCUPRO 12181905 is a solid carbide square end mill designed for precision milling operations in metal, composites, and plastics. Built from micrograin carbide, it delivers consistent cutting performance and edge retention in demanding machining environments. The 3-flute, spiral design with a 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. At 9/64 inch (0.1406 inches) in diameter with a 1/2 inch length of cut and 3/16 inch shank, this is a small-diameter tool suited for fine-detail work, slots, and pocketing operations. It is centercutting, allowing direct plunge entry into the workpiece. Installed by machinists and CNC operators in production and job-shop environments.

This end mill is suited for use in CNC machining centers and manual milling machines where tight-tolerance small-diameter cuts are required. The right-hand cut and right-hand flute configuration are standard for conventional and climb milling setups. The uncoated micrograin carbide construction is appropriate for dry or wet cutting applications depending on material and shop practice. Its regular length profile fits standard toolholders accepting a 3/16 inch shank diameter.

Key Features

• Micrograin solid carbide construction for superior edge retention and wear resistance
• 3-flute spiral design with 40-degree helix for efficient chip evacuation
• Centercutting capability allows direct plunge cuts without pre-drilling
• Right-hand cut and right-hand flute — standard for most milling setups
• Tight mill diameter tolerance of +0.000 / -0.002 inches for precision fitment
• Uncoated finish suitable for a range of materials and cutting fluids

Compatibility

Designed as a standard replacement or production end mill for CNC machining centers and manual mills accepting a 3/16 inch shank diameter with right-hand rotation.

Installation Notes

Installation is performed by a qualified machinist or CNC operator. Ensure the spindle is fully powered down and the tool is secured with the correct collet or toolholder sized for a 3/16 inch shank before operation. Verify runout and tool projection before cutting. Follow shop-specific speeds and feeds guidelines for the workpiece material and cutting fluid being used.
