The cutting edge on a good quality cobalt bit should last for longer than a standard HSS bit. Like other HSS bits, they are corrosion-resistant, which means they should retain their condition in all storage and usage conditions they’re likely to experience. However, cobalt can be brittle. If your cobalt drill bits aren’t cared for properly or are dropped, they can break – which can prove costly.

Nov 13, 2017 — A form tap in 6061 Aluminum should be at around 180-250 SFM so the 5,000 RPM recommended is right on and is a great starting point.

Welding nickel alloys requires specific welding processes and filler materials to ensure that the weld joints retain the desired properties, such as corrosion resistance and mechanical strength. The choice of filler materials depends on the specific nickel alloy and the welding process being used. Here are some common types of nickel alloys and filler materials used by welding nickel alloys:

They are most often used to cut through hardened and abrasive materials. Cobalt bits are able to cut through the most hardened metals, including bronze, cast iron, stainless steel and titanium. They are also able to cut through weld seams.

Jan 20, 2020 — During down milling, it should resist pulling forces. 5.Down milling VS up milling. 0. SHARES.

The strength of cobalt means that drill bits are better suited to the tough challenge of cutting through steel. Cobalt bits aren’t suitable for general applications. For less intensive operations, like drilling through wood, plastic or light metals, an HSS drill bit is perfect.

Nickel alloys offer good thermal conductivity and thermal expansion control, making them suitable for heat exchangers, steam generator tubing, and other applications requiring efficient heat transfer and dimensional stability over a range of temperatures.

Sturdy, hardwearing and robust, modern metal drill bits can cut through the toughest materials with no trouble. When it comes to drilling, selecting the right tool for the job is crucial. 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.

Over time, HSS drill bits can become blunt and need to be sharpened, which demands specialist tools that aren’t always available. If you’re using HSS drill bits for long periods or at high RPMs, you may need to use cutting fluid to keep the bit cool.

HSS bits are hardwearing and heat resistant. The large concentrations of chrome and nickel in stainless steel ensure that HSS bits are super strong and durable. HSS drill bits are capable of safely drilling through hardwood, some metals and plastic. They’re safe to operate at high speeds (RPM) and provide long-lasting performance – as long as they are maintained.

Nickel alloys exhibit resistance to creep, a phenomenon where materials deform over time under constant stress at high temperatures. This property is crucial in applications like power generation, where materials are subjected to prolonged stress at elevated temperatures.

It’s crucial for the safety of your tools and yourself that you use the right bit for the job. You will find cobalt drill bits stocked alongside other popular choices, including titanium coated, titanium nitride and tungsten carbide bits. Each of these has its strengths and weaknesses which you should be aware of before buying.

Cobalt bits are a combination of steel (or another alloy) mixed with a small percentage of cobalt, typically between 5 – 7%. Cobalt has a melting point of 1495°C and a boiling point of 2927°C, which makes it perfect for use at high temperatures. By combining a small amount of cobalt with another alloy, the results are incredible.

Nickel alloys find applications across a wide spectrum of industries, including aerospace, energy, chemical processing, automotive, electronics, healthcare, and more. Their diverse properties and versatility make them a vital class of materials that contribute to advancements in technology, engineering, and material science.

Nickel alloys are highly corrosion-resistant, making them ideal for applications in aggressive and corrosive environments. They resist corrosion from acidic and alkaline solutions, saltwater, and various chemicals. Industries such as chemical processing, marine engineering, and petrochemicals rely on nickel alloys for their corrosion-resistant properties.

Nickel  alloys are primarily composed of nickel, chromium, and other alloying elements and they are often used in demanding conditions such as high temperatures, chemical, corrosive environments and in the aerospace industry. Each nickel alloy is designed to meet specific requirements for corrosion resistance, mechanical properties, temperature resistance and other factors. Choosing the right alloy is essential to ensure materials perform in their intended environments and applications. As always, when selecting a material for a specific application, it's important to consider the specific corrosive environment, temperature, pressure, and other relevant factors to ensure the alloy's optimal performance and longevity. Consulting with a materials engineer or corrosion specialist can provide valuable insights for precise material selection based on your application's requirements.
