Accupro 12182601 Corner Radius End Mill 1/2 in 4 Flute

Product Description

The ACCUPRO 12182601 is a solid carbide corner radius end mill designed for precision milling operations in ferrous and non-ferrous materials. Built from micrograin carbide and coated with TiCN (Titanium Carbonitride), it delivers extended tool life and wear resistance in high-speed cutting environments. The 0.045 inch corner radius reduces stress concentrations at the cutting edge and produces consistent radii in pocketing, profiling, and finishing passes. With a 40-degree helix angle and 4-flute geometry, this single-end mill is suited for machinists and tool-and-die professionals running CNC machining centers or manual knee mills.

This end mill is used in general machining applications including pocket milling, contour profiling, and floor finishing where a controlled corner radius is required. The centercutting design allows direct plunge entry, adding flexibility in programming. At 3 inches overall length with a 1 inch length of cut, it fits standard short-reach setups. The 1/2 inch shank diameter seats in common ER and end mill holders across most CNC and manual milling platforms.

Key Features

• Solid micrograin carbide construction for rigidity and edge retention
• TiCN coating improves surface hardness and reduces built-up edge in ferrous materials
• 0.045 inch corner radius for consistent radii in pockets and profiles
• 40-degree helix angle promotes smooth chip evacuation and reduced cutting forces
• Centercutting geometry enables direct plunge milling without a pre-drilled entry point
• Right-hand flute direction and right-hand cutting for standard spindle rotation

Compatibility

Designed as an OEM-style replacement or standard tooling selection for CNC and manual milling machines accepting a 1/2 inch shank end mill holder.

Installation Notes

Installation should be performed by a qualified machinist following standard toolroom practices. Secure the shank fully within the holder to the recommended grip depth and verify runout before cutting. Confirm spindle speed and feed rate are appropriate for the workpiece material and coating before engaging the cut. Never exceed the tool manufacturer's recommended depth of cut for the given length of cut and diameter ratio.
