V-Bit End Mills
V-bit end mills are used for carving V-shaped depressions in the workpiece, also called V-carving. They come in either 60° or 90° V-bit. The sharp tips of the end mills are used to cut through narrow paths, while the wider bottom is used for larger cuts. This tapered end mill is best for especially sharp edges and corners, because of their radiuses.
With small angles and tips, produce a V-shaped pass, used for engraving, narrow cuts, and small, delicate engraving of lettering and lines, particularly for making signs, it’s also available for exceptionally sharp edges.
Cutting Tool Materials:
- High Speed Steel (HSS) provides good wear resistance and costs less than cobalt or carbide end mills. HSS is used for general-purpose milling of both ferrous and nonferrous materials.
- Vanadium High Speed Steel (HSSE) is made of high speed steel, carbon, vanadium carbide and other alloys designed to increase abrasive wear resistance and toughness. It is commonly used for general applications on stainless steels and high silicon aluminums.
- Cobalt (M-42: 8% Cobalt): Provides better wear resistance, higher hot hardness and toughness than high speed steel (HSS). There is very little chipping or microchipping under severe cutting conditions, allowing the tool to run 10% faster than HSS, resulting in excellent metal removal rates and good finishes. It is a cost-effective material ideal for machining cast iron, steel and titanium alloys.
- Powdered Metal (PM) is tougher and more cost effective than solid carbide. It is tougher and less prone to breakage. PM performs well in materials < 30RC and is used in high-shock and high-stock applications such as roughing.
