Product Details

Solid Carbide 1/4" Ball Nose 2 Flute End Mill -  This tool has a relief grind after the flutes so you can plunge deeper in your part without hitting the walls of the material. They are also great for deep pocket milling in wood, copper, brass, plastic and aluminum. These tools are coated with a proprietary HP-Astra™ High Performance coating that allows higher speed & feed rates as well as extended tool life & increased lubricity in abrasive material.  Made in USA.

Ball End Mills have a round tip used to machine curved details, also called Ball Nose End Mills, they are used for milling rounded slots, slopes, and contours. All are center cutting, allowing plunge cuts into a surface and machining 2D/3D dimensional contours with a smooth finish. Great for milling into all types of material including, wood, plastic, metal. etc. Use uncoated end mills for general purpose milling and short production runs. Use coated end mills for demanding, high-speed jobs in hard material as well as for longer production runs. They’re more wear resistant than uncoated end mills.
