FAQ:
Q: Which end mill to cut high speed steel?
A: The Niagara Cutter SEB270 TiCN-coated, high-speed steel, ball nose end mill has a long extended neck for milling slots and cavities and two flutes for general-purpose machining. The extended-reach neck style provides greater access to recessed areas of the workpiece than tools with a standard neck style.
Q: What are the types of end mills?
A: According to the different shape of the end, the end mill is separated into different types, like a square type endmill, ball type endmill, nose type end mill and so on. The gashing on the end of an end mill is for chip evacuation. Especially when plunging or when milling only using a small depth of cut.
Q: What are these tapered end mills used for?
A: Use these end mills for general purpose work in most material, such as aluminum, brass, bronze, iron, and steel. Also known as taper degree end mills, they’re often used to machine angled slots in dies and molds. All are center cutting, allowing plunge cuts into a surface.
Q: How are end mills made?
A: End mills are typically made on CNC (computer numeric controlled) tool and cutter grinder machines under high-pressure lubricants such as water, water-soluble oil, and high-flashpoint oil. Grinding inside the machine is accomplished with abrasive wheels mounted on a spindle (and in some cases, multiple spindles).
