Scrape-ResistanceCarbide is more scratch-resistant because of its hardness. Even titanium-coated HSS (High-Speed Steel) is weaker than carbide-tipped steel. You cannot use Carbide (Carb) in hand drills and drill presses for its hardness. Titanium scored 6 on the Mohs scale of mineral hardness, where carbide scored 9. HardnessCarbide is a lot harder than titanium. The exciting thing is that the titanium drill bit is not actually made of titanium if we exclude the coating. There is also an upgrade available from titanium nitride to titanium aluminum nitride, which multiples the tool’s life span. ConstitutionThe Carbide drill bit is a mixture of the hardest but fragile material, whereas the titanium drill bit is mainly made of steel coated with titanium carbonitride or titanium nitride. Though carbide is more expensive than the titanium drill bit, it is very cheap in comparison to other options for masonry use. You can get a titanium-coated bit at around $8 price. Major Differences of Carbide and Titanium Drill Bit CostTitanium drill bits are usually cheaper than carbide drill bits. Though you can use a carbide bit in the hardest materials, it can be broken easily because of its brittleness. High-quality equipment is mandatory for production drilling, and you need a tool holder to keep the equipment as well as your carbide drill bit safe. The Carbide drill bit is broadly used for production drilling. People prefer it for little hard tasks like drilling stainless steel. You can use TiALN in titanium, nickel-based materials, and high-alloy carbon steels.Ĭobalt bit is harder than HSS as it has a mixture of both cobalt and steel. Lastly, the violet-colored TiALN is not used for aluminum. It works excellent on more rigid materials like aluminum, cast iron, stainless steel, etc. It is gold in color and runs faster than uncoated drill machines. There are three types of titanium coatings available at present- Titanium Nitride (TiN), Titanium Carbonitride (TiCN), and Titanium Aluminum Nitride (TiAlN). If we talk about titanium drill bit, it is actually titanium coating on an HSS. People buy it at a low budget for simple drilling operations. High-Speed Steel is usually used for soft elements like plastic, wood, mild steel, etc. They are High-Speed Steel (HSS), Cobalt (HSCO), and Carbide (Carb). Three primary materials are used to make a drill bit. Their types or patterns affirm the task where you can use them. Accordingly, it would be best to have a specific drill bit for each tooling or machining operation. You can get various materials and coatings too.
