Liming · Titanium drill bits are HSS bits that have been coated with titanium nitride (TiN) using a process similar to electroplating. TiN is a ceramic material that increases the surface hardness of the bit and provides a thermal barrier by reducing friction.

Solid carbide cutting tools from Super Tool including solid carbide endmills, reamers, keyseats, drill bits and more for steel cutting, non-ferrous, cast iron, and stainless steel applications. Carbide tipped & high speed steel tooling also available.
And their temperature resistance allows faster machining. While drill bit “chattering” is the most common reason for bit failure, carbide tipped tools generally do not allow this to occur. Using carbide cutting tools has several advantages: Carbide tools are very efficient because they retain their cutting edge.

Liming · Both cobalt and titanium drill bits are able to work fine for a long time. But each type has its own peculiar properties. For example, sharpening titanium bits will grind off their coating, cobalt bits are great for tough steel but are brittle, etc. Read our short cobalt vs titanium drill bits comparison to choose the right bits for your project.
Eternal Tools offer a wide selection of diamond drill bits and tungsten carbide drill bits from 0.1mm all the way up to 65mm. For drilling stone, glass, metals
When you test tungsten carbide hardness you are mostly testing the amount of cobalt in it. You are also testing grain size to a certain extent as well as testing how well the carbide is made. Official ratings for carbide hardness are ballpark estimates at the best and don’t necessarily have much to do with how well the carbide will perform.
Liming · Solid Carbide Drill Bits - Near Diamond Drill Hardness Let You Drill to Remove Broken Tap, Bolt or Easy Out. Solid carbide drill bits for hardened steel. Australian importer. Solid carbide straight flute drills not just tipped drills. Drill grade 12 high tensile bolt, broken tap, easy out, screw extractor, hard bearing housings.
Tungsten carbide and other carbides are extremely hard and can drill virtually all materials, while holding an edge longer than other bits. The material is expensive and much more brittle than steels; consequently they are mainly used for drill-bit tips, small pieces of hard material fixed or brazed onto the tip of a bit made of less hard metal.
Carbide drill bits are incredibly effective in high production applications. Carbide allows very high cutting speeds, extensive tool life and the ability to cope in a wide spectrum of materials. Due to the hardness of carbide the cutting edge of the drill bit retains its effectiveness far beyond that of cobalt and HSS.
Liming · A carbide die drill is not the same thing as a carbide twist drill, a carbide tipped twist drill or the infamous masonary drill some have mentioned in other threads. This link has a photo and a bit of information to familiarize you with the tool, it''s not meant as a recommendation of the vendor.

Liming · 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.
The choice of drill bits when cutting through any material is important. Certain drill bit materials and shapes will cut through the material in different ways, each one creating a different effect or quality of cut. When cutting stee,l this is of even greater concern due to the hardness of the material. Many standard
