Accupro 12185132 Square End Mill 5/16 in 4 Flute Carbide

Product Description

The ACCUPRO 12185132 is a double-end, solid carbide square end mill designed for precision milling operations in metal fabrication and machining environments. It features a 5/16-inch cutting diameter, a 3/4-inch length of cut, and a 40-degree helix angle that promotes efficient chip evacuation and smooth cutting action. The TiCN (Titanium Carbonitride) finish increases surface hardness and wear resistance, extending tool life in demanding applications. With four spiral flutes and a centercutting design, this end mill handles slotting, profiling, and plunge cuts. It is installed and operated by machinists and CNC tooling professionals working with vertical and horizontal machining centers.

This end mill is suited for general-purpose milling of ferrous and non-ferrous materials in job shop and production environments. The micrograin carbide substrate supports tight tolerances and consistent performance across repeated tool passes. The double-end configuration provides two usable cutting ends, offering extended service life per tool. The 3/8-inch shank diameter fits standard collets and end mill holders commonly found on CNC mills and manual knee mills. Regular-length geometry makes it a practical choice for standard-depth cavity and contour work.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance
• TiCN finish increases surface hardness and reduces friction at the cutting edge
• 40-degree helix angle promotes efficient chip flow and reduced cutting forces
• Centercutting design allows direct plunge entry into workpiece material
• Double-end configuration delivers two usable cutting ends per tool
• Right-hand cut and right-hand flute spiral for standard CNC and manual mill setups

Compatibility

Designed for use in standard collet chucks and end mill holders accepting a 3/8-inch shank diameter, compatible with CNC vertical machining centers, CNC routers, and manual knee mills configured for solid carbide tooling.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's toolholding specifications. Ensure the spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the collet or end mill holder and torque the retention mechanism to the holder manufacturer's specification. Confirm runout with a dial indicator before beginning a cut, particularly for tight-tolerance work.
