Tungsten carbide drill bits for metal

Posted on August 12, by Ruwag UK. Carbide drill bits are extremely tough bits that are ideal for masonry and other heavy-duty projects. These bits are made of tungsten carbide, with many also containing small amounts of other metals such as cobalt to improve their durability.

Tungsten carbide drill bits for metal

Machine shops, maintenance personnel, and the manufacturing community overall face off against a veritable universe of different materials each day:. These include D2, A2, H13, S7, and other tough, heat-treatable, and wear-resistant metals used to make everything from plastic injection molds to stamping dies to high-speed steel HSS cutting tools. Read on. Otherwise, just know that so-called Mushet steel, which most consider the first true tool steel, left the furnace more than years ago. Because it could cut metal much more quickly than the hardened carbon steel tools of the day, they dubbed it high-speed steel. As you will see, that moniker has since become a bit misleading, as tungsten carbide cutting tools—though a bit less forgiving than HSS—are far faster and therefore much more productive. Regardless, metallurgists have continued adding various amounts and kinds of alloying elements to the tool steel crucible, among them tungsten, vanadium, chromium, and, most relevant to this discussion, cobalt. The result is six distinct groups of tool steel and many dozens of grades, a few of which we mentioned previously. The M-series, for instance, gets its name from the primary alloying ingredient, molybdenum, a hard, heat-resistant element sitting at number 42 on the periodic table. Compared to regular M2 tool steel, M35 and M42 are indeed super. Either way, be sure to follow the cutting tool manufacturer's recommendations. This last point is important, since all cutting tools, whether they are HSS, cobalt, or tungsten carbide more on this shortly , benefit from coating, be it TiN titanium nitride , TiAlN titanium aluminum nitride , or one of the other many tool coatings available on the market today. Cobalt, however, will in most cases last longer than its less wear and heat-resistant cousin, and as we've seen, run much faster besides. The only caveat is that cobalt drills, due to their greater hardness, are more brittle than HSS.

When it comes to drilling through tough materials, tungsten carbide drill bits are the gold standard. These specialized drill bits are made from carbide and tungsten, making them incredibly strong and durable. Tungsten carbide drill bits have several advantages over traditional steel ones. They can also withstand higher temperatures without breaking down or melting, as some steel bits can. When using tungsten carbide drill bits, taking certain precautions is important to get the best results possible.

Tungsten carbide drill bits for metal

These jobbers' -length bits have the rigidity and length required for most applications. Made of solid carbide for the highest accuracy and longest tool life, they are harder, stronger, and more wear resistant than high-speed steel, cobalt steel, and carbide-tipped bits. They retain a sharp, hard edge at high temperatures for the best performance on hard and abrasive material. The four-facet point keeps the bit centered without a pilot hole. These bits require rigid toolholding to prevent breakage and should not be used in hand-held drilling applications. Titanium - nitride TiN coated drill bits last longer and can drill at higher speeds than uncoated drill bits. Titanium - aluminum - nitride TiAlN coated drill bits are the most wear and temperature resistant for the longest life and highest drilling speeds.

Are you sure you want to leave? At the end of the day, choosing the right tool means doing the math, asking questions, and being open to new technologies. Back to Blog. Cobalt bits are made with a steel alloy that contains a small amount of cobalt. With that said, their strength can also make them brittle, meaning that they can break if not used correctly. Mixed Materials. Alexa Actionable Analytics for the Web. Session expired due to inactivity, please login again. Many bits are tipped with a second layer of metal that makes them tougher and increases corrosion resistance. Recent Articles.

Carbide drill bits are made from tungsten carbide, a compound of carbon and tungsten. This material provides faster cutting speed, more durability, and longevity.

The M-series, for instance, gets its name from the primary alloying ingredient, molybdenum, a hard, heat-resistant element sitting at number 42 on the periodic table. Since then, this extremely hard and wear-resistant material has consumed an enormous swath of the cutting tool market, drill bits included. Secure transaction.
