HSS drill bits are capable of safely drilling through hardwood, some metals and plastic. The large concentrations of chrome and nickel in stainless steel ensure that HSS bits are super strong and durable. HSS bits are hardwearing and heat resistant. In this article we describe the difference between High-Speed Steel (HSS) and cobalt drill bits, their strengths and weaknesses, and when you should use them. When it comes to drilling, selecting the right tool for the job is crucial. Sturdy, hardwearing and robust, modern metal drill bits can cut through the toughest materials with no trouble. You can also check out our Online Store for various types of drill bits when replacing your worn out dull redundant drill bits.The Difference Between HSS and Cobalt Drill Bits No drill bit lasts forever, check out our post on “How Long Do Drill Bits Last?” for further information on how long they last and recommendations of how and when to replace your drill bit.

RUKO UK stock both Cobalt and HSS drill bits online with Free Next Working Day Delivery when you spend over £50. However, for challenging Steel, Iron, Bronze or Titanium it is recommended that Cobalt should be considered for its high heat resistance and longevity when drilling. The Cobalt drills will not be adequate for the use within wood or plastic as it would cause damage to the surface material, whereas HSS would not be the most adequate material for cast iron, bronze, titanium or hard steels as it could potentially wear damage to the drill bit.įor general DIY small-scale usage, on multiple surfaces and applications, HSS is the better option for the best all round, cost effective, versatile drilling process. HSS is better for the lighter metals as well as wood and plastic applications.

Cobalt being a more expensive option are typically used by professional construction users and trades personnel for specific purposes.Ĭobalt is suitable for stronger metal drilling, such as Hardened Steel, Stainless Steel, Cast Iron, Bronze and Titanium as well as being well suited for drilling through weld seams. Making HSS Drills more suited for the general multi-purpose use activities such as small-scale DIY tasks. HSS Drill bits are a more economical option in comparison to Cobalt Drill bits and is the most cost-effective drill bit type available. Cobalt Bits are more brittle and so are susceptible to chipping. High-Speed Steel Bits are more elasticated in comparison to Cobalt Bits making them more flexible and adaptable for different drilling scenarios. Cobalt also offers the advantage of being more heat resistant over standard HSS, allowing for longer running time performance when undertaking any drilling activity. HSS drill bits are recommended for Light Metals, Wood and Plastic drilling.Ĭobalt is stronger than HSS, making it better for heavy duty drilling applications with a more rapid high-speed endurance. In addition, they can be resharpened to increase their lifespan. The material is flexible and can be used for a hand drill as well as a drill press. HSS has strong wear resistance with an increased hardness level. It is most commonly used within cutting and drilling tools as an ideal economic cost-effective material for general purpose applications such as DIY jobs and small-scale projects. High-Speed Steel is a form of carbon steel with additional elements that potentially could include chrome and vanadium. HSS is an abbreviation of High-Speed Steel. Check out our blog posts here.įor intense Steel drilling then Cobalt is most suited, however for more general applications, HSS is recommended. RUKO UK offers tips, guidance and advice on drilling through materials such as Hardened Steel, Aluminum Drilling and Titanium Drilling. Cobalt Drill Bits also have strong heat resistance allowing for deep drilling into tough metal material. The high durability of Cobalt material gives the Cobalt Drill Bits a long-lasting lifespan. The strong mass and high melting point makes it a hard metal ideal for the toughest applicational uses. The metal is within a group of transition metals as one of only three ferromagnetic transition elements alongside Iron and Nickel. It has an Atomic Mass of 58.933195 u and a Melting Point of 1,495 ☌. Cobalt (symbol – Co) is a chemical element found within the Earth’s crust as a chemically combined form. This helpful article guide will do a head-to-head comparison between High-Speed Steel (HSS) and Cobalt to determine which is the stronger and more suitable metal material for drill bit tools.Ĭobalt is a combination of an alloy (typically Steel) mixed with Cobalt. With so many Drill Bit options it is hard to decide which is appropriate for the task in hand.
