0.0500" (1.27mm) x .150" LOC AlTiN 2-Flute Corner Radius .005" Carbide End Mill, 1/8" Shank | K173

Kyocera .0500" 2-Flute AlTiN Corner Radius Carbide End Mill – K173

This Kyocera 2-flute corner radius carbide end mill features a .0500" (1.27mm) cutting diameter, a precision .005" (0.127mm) corner radius, a .150" length of cut, and a standard 1/8" shank. The tool is manufactured from solid micrograin carbide and features an AlTiN (Aluminum Titanium Nitride) coating for improved wear resistance during demanding CNC milling applications.

Unlike a sharp square end mill, the corner radius geometry provides a small rounded transition at the cutting edges. This helps reduce stress concentration and the potential for corner chipping, making the cutter useful for precision profiling, contouring, slotting, and semi-finishing operations where cutting-edge durability is important.

The 2-flute up-cut spiral design supports chip evacuation during machining. The AlTiN coating provides improved resistance to heat and abrasive wear, making this cutter particularly suitable for controlled machining of steels and other compatible engineering materials when appropriate cutting conditions are used.

Specifications

Corner Radius vs. Square End Mills

A corner radius end mill combines a primarily flat cutting end with a small radius at each cutting corner. The rounded corners can help improve edge durability, especially in applications where sharp corners are susceptible to chipping. Unlike a sharp square end mill, the tool leaves a small radius at the corresponding machined corner.

Machining Considerations

This is a small-diameter precision carbide cutter. Use rigid workholding, minimal spindle runout, suitable feeds and speeds, and appropriate chip evacuation. For steel or other harder materials, adjust cutting conditions to the specific workpiece and machine capabilities.
