21 Shocking Facts About Cobalt Vs High Speed Steel | High Speed Steel: From which steel are drills made of
- Compared to regular M2 tool steel, M35 and M42 are indeed super. Where “regular” M2 HSS comes in at a hardness of around 62 HRC, M35 starts at 65 HRC and M42 measures 67 or so. That doesn’t seem like much difference, but together with cobalt’s greater heat resistance, it supports higher cutting speeds—depending on the brand and whether the drill is coated, this might mean 50% faster spindle RPM and commensurately higher feedrates. Either way, be sure to follow the cutting tool manufacturer’s recommendations. - Source: Internet
- Length : The durability of the bit also depends on the length. As the length of the bit increases, the durability and toughness of the bit decreases. All in all shorter cobalt bits withstand breaking, spinning and twisting. - Source: Internet
- The very best drill bits are “Fully Ground” which means the bit was ground out of the one piece of raw material, and as such are very precise and strong. The table below outlines some of the more popular answers as to the second question: What material are they made from. All of these HSS drill bits are superior to carbon steel in that they can withstand higher temperatures without losing their temper (hardness). This property allows HSS to cut faster, and at room temperature HSS grades generally display high hardness. The types of HSS Steel used in Drill Bits are below: - Source: Internet
- As to the question “when should a cobalt drill bit be used," the answer is straightforward: anywhere you would use an HSS drill. 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. The user must therefore take extra care to align them properly and avoid the radial tool pressures that might occur when drilling into intersecting holes (hydraulic manifolds, for example) and angled surfaces. - Source: Internet
- They are mostly used for cutting through abrasive and hard materials. Cobalt bits have the ability to cut through the hardest of metals, including cast iron, bronze, titanium and stainless steel. They can also easily cut through weld seams. - Source: Internet
- Because of their durability and cost, most Pros don’t use cobalt drill bits for general purpose use. The extra hardness lets manufacturers make the flutes smaller as a percentage of the total thickness, increasing the strength of the bits. You can also sharpen them without losing cutting effectiveness. Cobalt bits cost more than TiN or Black Oxide bits, but many Pros find value in the toughness. - Source: Internet
- A good rule of thumb is to always start slowly until the drill bit cuts into the metal before increasing the speed. Stop drilling occasionally and top up on lubricant as needed. If the metal starts to squeal, smoke or discolour when drilling then you’re going too fast. Slow down (and lubricate)! - Source: Internet
- Black oxide bits last up to 50% longer than standard HSS bits. They offer superior durability and speed. Many pros find they get years of use from them and consider black oxide bits the best general-purpose drill bits you can buy. - Source: Internet
- All of the different types of drill bits in these categories are based on High-Speed Steel (HSS), a designation you’ll see often when reading about bits. But the treatments those HSS bits receive to make them black oxide, titanium, or cobalt make marked changes in the performance, intended use, and longevity. Learning the differences helps you avoid wasting money and using the wrong bits for the wrong materials. - Source: Internet
- Steels are generally divided into structural and tool steels. Tool steels are used, among other purposes, for cutting hand and machine tools. All tool steels are stainless steels. - Source: Internet
- HSS vs Cobalt – General Information HSS is a tool high carbon steel, containing a significant dose of tungsten. A typical HSS alloy has: about 15% tungsten, 5% Chromium, 1% Vanadium, 0.7% carbon. Check HSS Bits Price and Availability For better wear resistance and higher - Source: Internet
- TiN (Titanium Nitride) coatings can increase the wear resistance and lubricity at the cutting point and facilitate use higher speeds and feeds and improve tool life. TiN coated tools can easily be identified by the characteristic golden colour coating on HSS tools. TiN coating can increase the cost of drills by 30 to 50% depending on size and batch quantity and practically about 30-100% increase in drilling speeds can be applied with coated drills. - Source: Internet
- HSS are heat resistant and hardwearing drill bits. The huge concentrations from nickel and chrome in the stainless steel makes sure that HSS bits are durable and strong. HSS drill bits can safely drill through hardwood, plastic and some types of metal. - Source: Internet
- High-speed steel is alloyed with 5-8% cobalt to create cobalt drill bits. These are the best drill bits for metal due to their high resistance to the massive heat generated when drilling through highly abrasive and/or hard materials such as treated stainless steel, titanium, and cast iron. Unlike the TiN coating, cobalt is found throughout the entire material which makes it great for high production work. - Source: Internet
- M35 is similar to M2, but with 5% cobalt added – NOTE: M42 is almost the same but with 8% cobalt and is generally considered a very specialised bit and is more brittle than M35. The key purpose of adding up the cobalt is to enhance the heat resistance capacity and durability of the bits, however, it is very important to note that M35 bits work best and last longest if run at slow working speeds with lubricant. Used primarily for drilling Stainless Steel, these bits gain the property of endurance against the high temperature due to cobalt metal.This HSS material was developed to tackle drilling of tough materials like Stainless steel, Inconel, tool steels and titanium alloys. - Source: Internet
- Tip point style: Tip style will determine the penetration capacity of bit through the material. The 135° Quick-Cut points are self-centering and penetrate quickly with less pressure. The 135 degree split point style is most commonly used in cobalt drill bits and are the recommended tip type when drilling steel. - Source: Internet
- 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. This results in increased production rates, corrosion resistance, and 3 to 6 times longer tool life. Titanium bits are suitable for drilling iron, steel, aluminum, magnesium, and wood. - Source: Internet

We also have auger and brad-point drill bits for the woodworking industry, masonry SDS Plus drill bits, and specialised glass / tile drill bits with a unique 4 tip design. - Source: Internet
- M2 is a HSS drill bit compound that has high wear resistance and is used in all general steel drilling applications involving standard / mild / black steel. M2 retains its cutting edge longer than other general purpose high speed steel drill bits when working in general steel engineering applications, however, is not as shock resistant or as flexible as other HSS grades with less tungsten. Drill bits made from M2 material are generally favoured for high production machine work. - Source: Internet
- Manufacturers heat HSS bits to 950 degrees Fahrenheit, creating a black oxide finish that resists rust and corrosion. This reduces friction between bit and workpiece, thereby speeding up the drilling process. Bits made with a black oxide coating are suitable for work on steel, copper, aluminum, brass, oak, maple, MDF, pine, PVC, polycarbonate, acrylic, ABS, nylon, and composite materials. - Source: Internet
- Titanium bits are great for general purpose drilling in a production environment because they drill quickly. The TiN coating also helps chips flow thru the flutes which is helpful because some materials – like aluminum – adhere to bits more than others. However, once the tip is dulled, it won’t regain it’s cutting edge without being recoated in titanium nitride. It usually makes more sense to replace rather than recoat them. So even though they are harder than cobalt, their edge is only skin-deep. - Source: Internet
