Accupro 12181265 Corner Radius End Mill 1/8 in 2 Flute

Product Description

The ACCUPRO 12181265 is a solid carbide corner radius end mill designed for precision milling operations in metal fabrication and machining applications. It features a 1/8 inch diameter cutting edge with a 1/2 inch length of cut and a 0.045 inch corner radius, delivering smooth, radiused profiles on workpiece edges and pockets. The 2-flute geometry combined with a 40-degree helix angle promotes efficient chip evacuation and reduces heat buildup during cutting. A TiCN coating increases surface hardness and wear resistance, extending tool life in demanding materials. Licensed machinists and CNC operators install this tool in standard 1/8 inch collet or end mill holders.

This end mill is suited for light finishing and profiling passes in materials such as steel, stainless steel, aluminum, and high-temperature alloys where a consistent corner radius is required. Its single-end, centercutting design allows for plunge entry as well as conventional peripheral and slot milling. The right-hand cutting and right-hand flute direction are standard for most CNC machining center setups. It is appropriate for both job shop production and toolroom applications requiring tight dimensional control.

Key Features

• 0.045 inch corner radius for consistent radiused edge profiles
• Solid micrograin carbide substrate for rigidity and wear resistance
• TiCN coating for extended tool life in ferrous and abrasive materials
• 40-degree helix angle promotes efficient chip evacuation
• Centercutting design allows direct plunge entry
• Right-hand cut, right-hand spiral flute direction for standard CNC setups

Compatibility

Designed as an OEM-style replacement or direct-fit tool for CNC machining centers and manual mills equipped with 1/8 inch collet or end mill holders requiring a corner radius end mill profile.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully powered down and locked out before changing tooling. Seat the 1/8 inch shank fully and evenly in a matched collet or end mill holder and torque the retention nut according to the holder manufacturer specifications. Verify runout with a dial indicator before beginning cuts to protect both the tool and the workpiece.
