2 Flutes Solid Carbide Drill Bit With Inner Coolant Hole For Stainless Steel
What is the carbide drill bit?
Carbide drill bits are made out of tungsten carbide, although they often contain small amounts of other materials,
such as cobalt, to reduce their reactivity with iron. You can usually find carbide drill bits in one of two forms: carbide-tipped
or full-body.Carbide tips can drill through hard, non-metallic materials like masonry, while full-body drill bits are primarily used in automated processes.
They stay sharper longer than cobalt drill bits do, and they have a higher cutting speed. They can also handle higher temperatures.
