Using drill press will save you a lot of time, efforts and help you to avoid bit breakage. We can talk about the best drill bits, but let’s talk about the differences between black oxide, titanium, and cobalt drill bits. In terms of surfaces to drill, cobalt is used on hardened steel while tungsten carbide is usually reserved for masonry. Iron carbide if memory serves) so … Unlike the TiN coating, cobalt is found throughout the entire material which makes it great for high production. This is the hardest and most fragile material used in bit production, and bits made from it should not be used in hand drills. It usually contains 94% tungsten carbide, 6% cobalt and 1% other metals, also known as tungsten steel. These are especialy effective in very soft materials like plastics and aluminums. Taper Length These include red-hardened steel, stainless steel, and other sturdy materials. Twist Drills .
