Accupro 12185130 Square End Mill 9/32 in 4 Flute Carbide

Product Description

The ACCUPRO 12185130 is a double-end square end mill ground from solid micrograin carbide and coated with AlTiN for extended tool life in ferrous and high-temp alloy cutting applications. It measures 0.2813 inches (9/32 inch) in mill diameter with a 3/8-inch shank and an overall length of 3.5 inches. The 4-flute, spiral-flute geometry runs a 40-degree helix angle, promoting efficient chip evacuation and smooth finishes on peripheral and slot milling passes. The centercutting design allows plunge entry. This end mill is installed and used by machinists and toolroom operators on CNC mills, manual knee mills, and machining centers.

The 12185130 is suited for production and toolroom milling operations where a compact cutting diameter and standard-length reach are required. The 11/16-inch length of cut supports shallow-to-moderate slot and profile work. The double-end configuration provides a second usable cutting end, extending service intervals before tool replacement. The AlTiN coating performs well in dry or minimum-quantity lubrication (MQL) cutting environments, particularly in steels, stainless steels, and cast iron. Right-hand cut and right-hand flute orientation are standard for conventional CNC spindle rotation.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance
• AlTiN coating for heat resistance and extended tool life in ferrous materials
• 40-degree helix angle spiral flute for efficient chip flow
• Centercutting geometry allows direct plunge entry
• Double-end design provides two cutting ends per tool
• Right-hand cut, right-hand flute for standard CNC spindle use

Compatibility

Designed for use in 3/8-inch collets, end mill holders, or shrink-fit toolholders on CNC machining centers and manual milling machines requiring a 9/32-inch cutting diameter.

Installation Notes

Installation is performed by machinists using a properly sized collet or end mill holder torqued to the toolholder manufacturer's specification. Confirm shank runout at the holder before cutting. Always power down and lock out the spindle before changing tooling. Verify cutting direction matches spindle rotation before initiating a cut.
