4 HSS Straight End Mills 4 Teeth For Metal Wood Milling Drill

Square shank end mills made of high quality high quality steel, with the characteristic of high toughness, extremely wear resistant, high speed cutting, high hardness. The milling tool adopts negative lead angle and large core design, which strengthens rigidity and sharpness, making cutting and chip removal more stable, improving machining efficiency. With a double-edged spiral angle of 35", it makes the cutters more permeable and reduces product burr. Extra large chip removal space that makes the machining process smoother and more efficient, achieving high precision and brightness products. Perfect for CNC data machine, milling machine, drilling machine for milling copper, aluminum, tool steel, cast iron and direct machining or fine processing of heat treatment mold.
