#BLACK AND GOLD DEWALT DRILL BITS PROFESSIONAL#

They are the cheapest, most easily affordable of the three.Ĭobalt drill bits are the most expensive, which makes them impractical for daily casual use. Costīlack oxide drill bits win this round. Hence, cobalt bits are more durable.Īlthough black oxide drill bits can also be re-sharpened, they cannot defeat cobalt bits in durability because of their hardness. Due to the uniform concentration of cobalt in the drill bit, it can be sharpened if it loses its edge or gets worn at the head. Instead, they are made of a 5-8% cobalt alloy with high-speed steel. Cobalt bits, unlike titanium bits, are not coated with cobalt. The TiN coating on titanium drill bits gets eroded over time, decreasing their durability. In contrast, cobalt bits are custom made for drilling on materials like cast iron, stainless steel, and one of the most demanding metal, titanium. Durabilityīecause of their hardness and strength, cobalt drill bits are the most durable of the three.īlack oxide and titanium drill bits tend to lose their edge when used constantly on challenging material. Titanium bits are used for moderate drilling purposes.

Cobalt drill bits, being hard and tough, are used to drill through hard metal and used for industrial purposes.

Purposeīlack oxide drill bits are the best general-purpose drill bits, whereas cobalt drill bits are the best professional drill bits.īeing affordable and pocket-friendly, black oxide bits serve all kinds of purposes and are the right choice for handy amateur persons, DIYers, or hobbyists. Even though cobalt bits are perfectly capable of drilling through soft material as well, it is generally preferred to use cheaper bits for such purposes.

Titanium bits are used for drilling through iron, steel, magnesium, aluminum, and wood.Ĭobalt drill bits are used only for drilling through hard material like cast iron, stainless steel, and titanium. Black oxide can be used to work on wood such as oak, maple, pine, metals like steel, copper, aluminum, brass, etc., as well as plastic. Materialīlack Oxide drill bits are most versatile when it comes to drilling material. Black oxide, on the other hand, is a regular HSS bit heated to 950 Fahrenheit for black oxide finish, so it is not as hard as titanium, let alone cobalt drill bits. Whereas, cobalt drill bits have a uniform concentration of cobalt throughout, making them harder. While titanium is a pretty hard material, titanium drill bits are only coated with a thin layer of titanium nitride, which erodes quickly. Out of the three, cobalt drill bits are the hardest. Compared to cobalt bits, titanium bits are nowhere near it in strength, toughness, and durability.īlack Oxide Vs Titanium Vs Cobalt: Differences 1. While titanium drill bits have more or less the same uses as black oxide, the latter is much cheaper. In addition to being non-corrosive, durable, and fast like titanium bits, cobalt and black oxide bits can be re-sharpened. Also, cobalt bits are quite expensive, so it is not advised to buy it for DIYs or hobbies.Ĭompared to titanium drill bits, both black oxide and cobalt drill bits are better. Their high heat resistance and ability to cut through hard metals make them ideal for specialist work. On the other hand, cobalt drill bits are best for professional work. You must keep in mind your needs and requirements very specifically, then only you can decide which of the types mentioned above is best for you.Īfter conducting in-depth research and tests, we have concluded that black oxide drill bits are best suited for amateurs, as they serve for all general purposes, can work on a vast array of materials, and are easily affordable.
