![]() TiCN – Titanium Carbo-Nitride is harder and more durable than other coatings. TiN – Titanium Nitride resists friction and improves the heat transfer, providing longer life in comparison with standard high-speed steel bits. They feature “red hardness” and hold their edges when drilling the toughest materials. Most non-industrial users, with industrial tooling and machinery to work steel are going to blunt the cutting edge through gross edge damage from imperfect alignment and uncontrolled feeding, not through gradual wear, which is where TiN is of benefit.Ĭobalt HSS offers no advantage in drilling wood, mild steel, and softer non-ferrous metals.Comparison of titanium vs cobalt drill bits shows, that cobalt drills are intended for stainless and hardened alloy steels where heat and abrasion are factors in the cutting environment. ![]() Unsurprisingly they’re also a bit more brittle so are easier to breakĬomparison of cobalt vs titanium drill bits shows, that in soft abrasive material such as plastic and wood, the coating improves the life of the tool and reduces the cutting temperature. They have better heat resistance, are harder, allow higher cutting speeds. Widely used grades alloyed with cobalt M42 is 8% and M35 is 5% cobalt. ‘Cobalt’ bits are HSS bits with cobalt in alloy. “Titanium” bits are made of carbon steel, SS (Speed Steel) or HSS (High Speed Steel) with TiN (Titanium Nitride, gold color), TiCN (titanium carbo-Nitride, TiALN (titanium aluminum nitride, violet color), AlTiN (titanium aluminum nitride)īest titanium drill bits set – DeWALT DW1361 Titanium vs Cobalt Drill Bits – General Information Cobalt vs Titanium Drill Bits Comparison (Cobalt vs HSS Comparison) Using cutting fluid keeps the bit cool and prolongs a lot the life of the bit. Used in a hand drill, it is easy to break through the coating (or definitely when sharpening) and then you have an HSS bit (not so bad too).Ī high-quality HSS bit is fine, as long as you keep them sharp it’s a reasonable investment. Learn how to sharpen them with a bench grinder, or better a drill doctor (but get one of the higher end ones that will do split points). Heat kills bits. ![]() Especially in automated systems, which drill lots of closely controlled holes. The titanium bits work great for metal cutting machines. Read our short cobalt vs titanium drill bits comparison to choose the right bits for your project. For example, sharpening titanium bits will grind off their coating, cobalt bits are great for tough steel but are brittle, etc. But each type has its own peculiar properties. Cobalt drill bits are high-quality materials such as aluminum, carbon steel, and alloy steel, and have a rounded edges that prevent the metal from fromipping or dipping of the product.Both cobalt and titanium drill bits are able to work fine for a long time. ![]() They also have high resistance, ective trenching tools are necessary to avoid cutting or corrosion of any material.Ĭobalt steel drill bits are great for heavy-duty work jobs, they also come in a variety of colors, sizes, and designs. ![]() As a result, cobalt drill bits are great in long-lasting applications that such as hot pipes, or any other holes that require a specialized drive, they can come in handy, for forging, or protecting materials from damage. They have high resistance and trenching tools, such as screwed drills, are able to withstand heavy loads, and for a very long time, they are very useful, and can be used for protecting materials from damage, as well as other objects. What are the benefits of cobalt drill bits?Ĭobalt drill bits are great for protecting a surface from damage, and can also be used for driving or protecting materials from damage. ![]()
