Why are carbide bits so expensive?
Cobalt is in short supply, and the rise in cobalt prices affects the price of tungsten carbide raw materials. Whether it is a mobile phone battery or an electric vehicle battery, it requires a lot of cobalt. Cobalt is in short supply, so the price of cobalt has also raised all the way.
What are solid carbide drills used for?
Carbide drills are generally used for high-volume hole production, where the higher tool cost can be justified on a cost-per-part basis. For deep high-volume holes, they are often available with internal coolant ducts, resulting in longer tool life and stable production.
What is difference between carbide drill and HSS drill?
Carbide steel has more high cutting speed and is 4- 7 times higher than high – speed steel. Carbide is much harder, so it has a longer tool life and faster cutting data than conventional high speed steel. HSS tools also cost less than Carbide tools and are often a good solution in high-mix, low-volume applications.
Are carbide drill bits worth it?
They’re tougher than basic HSS bits and stay sharp longer. They work for drilling wood, metal, fiberglass and PVC. Carbide-tipped drill bits stay sharp much longer than steel, HSS or titanium bits. They’re effective for drilling tile and masonry.
What is a carbide drill bit?
Carbide (Carb) is the hardest and most brittle of the drill bit materials. It’s used mostly for production drilling where a high-quality tool holder and equipment is used. It should not be used in hand drills or even drill presses. These drill bits are designed for the most demanding and hardest materials.
How are solid carbide drills made?
The ore is crushed, heated and treated with chemicals. The result: tungsten oxide. Then, the fine particles of tungsten oxide are carburized, turning them into tungsten carbide. In one method, the tungsten oxide is mixed with graphite (carbon).
Is tungsten carbide the same as solid carbide?
Tungsten steel is a part of solid carbide, but solid carbide is not necessarily tungsten steel. Simply put, all the alloy whose hardness goes beyond HRC65 can be called solid carbide. Tungsten steel is only a kind of solid carbide with a hardness between 85 and 92 HRC, which is often used to make CNC router bits.
Is carbide harder than steel?
Carbide is much denser than both steel and Titanium. Its finished product is often polished and finished with harder abrasives such as diamonds. It’s truly a versatile and durable material.
How much is carbide worth per pound?

What are carbide drill bits made of?
tungsten carbide
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.
Is carbide stronger than steel?
Tungsten carbide is a very hard material. It has been projected as falling somewhere between 8.5 and 9 on the Moh’s hardness scale, just behind diamonds. This makes it a valuable metal with many different applications. This rigidity makes tungsten stronger than both steel and titanium.
