Accupro 12181540 Corner Radius End Mill 3/4 in 2 Flute

Product Description

The ACCUPRO 12181540 is a solid carbide corner radius end mill designed for precision milling operations in metalworking and machining applications. It features a 3/4 inch diameter with a 0.01 inch corner radius, a 1-1/2 inch length of cut, and a 4 inch overall length. The tool is coated with TiCN (Titanium Carbonitride), which improves wear resistance and extends tool life in ferrous and non-ferrous cutting. The 2-flute, right-hand spiral geometry and 40-degree helix angle promote efficient chip evacuation. Micrograin carbide substrate adds toughness and edge retention. This end mill is installed and used by machinists and tool-and-die professionals in CNC and manual milling operations.

This end mill is suited for finish milling, profiling, and contouring operations where a controlled corner radius is required to reduce stress concentrations in the workpiece. It performs well in steel, stainless steel, and hard alloys. The centercutting design allows plunge cutting, making it versatile for pocketing and slotting operations on vertical machining centers and CNC mills. The single-end configuration is standard for high-precision toolpath work where runout and geometry consistency are critical.

Key Features

• TiCN coating for increased hardness and wear resistance in ferrous and non-ferrous materials
• Micrograin solid carbide substrate for edge stability and longer tool life
• 0.01 inch corner radius reduces stress risers and improves surface finish at part corners
• 40-degree helix angle promotes smooth cutting action and efficient chip evacuation
• Centercutting design enables plunge milling and ramp entry
• Right-hand cut and right-hand spiral geometry for standard CNC and manual mill spindle direction

Compatibility

Designed as a standard shank corner radius end mill compatible with 3/4 inch collets, end mill holders, and shrink-fit toolholders used on vertical machining centers, CNC mills, and manual knee mills.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully powered down and locked out before changing tooling. Seat the 3/4 inch shank fully and evenly in the toolholder to the recommended gauge length to minimize runout. Verify spindle direction is set to right-hand rotation before engaging the cut.
