Accupro 12182948 Corner Radius End Mill 1/2 Inch 4 Flute

Product Description

The ACCUPRO 12182948 is a solid carbide corner radius end mill designed for precision milling of ferrous and hard materials in CNC machining applications. It features a 1/2 inch diameter with a 1/8 inch (0.1250 inch) corner radius, a 5/8 inch length of cut, and a 2-1/2 inch overall length. The four-flute, right-hand spiral geometry combined with an AlTiN coating provides thermal resistance and wear performance at elevated cutting speeds. The micrograin carbide substrate supports tight tolerances and consistent edge integrity across production runs. This end mill is used by machinists in job shops, tool rooms, and production environments.

This end mill is suited for profiling, slotting, and finishing operations on steel, stainless steel, cast iron, and other hard materials. The stub-length flute profile offers rigidity in applications where deflection control is critical. The single-end, centercutting design allows direct plunge entry as well as conventional ramping and contouring. A 1/2 inch shank diameter fits standard ER and side-lock toolholders used on vertical and horizontal machining centers.

Key Features

• 1/2 inch mill diameter with 1/8 inch corner radius for blended edge transitions
• AlTiN coating for oxidation resistance and extended tool life at high cutting temperatures
• Micrograin solid carbide substrate for edge stability and wear resistance
• 4-flute, right-hand spiral with right-hand cutting direction
• Centercutting geometry allows direct plunge entry
• Stub-length flute type maximizes rigidity and minimizes deflection

Compatibility

Designed as an OEM-style replacement or direct-fit cutting tool for CNC machining centers and manual mills accepting a 1/2 inch shank end mill holder.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's toolholder torque and runout specifications. Ensure the machine spindle is fully stopped and the tool is secure in a properly cleaned collet or toolholder before beginning any operation. Verify shank diameter tolerance fit against the holder specification before clamping. Follow applicable shop safety procedures and machine guard requirements during setup and operation.
