The Ultimate Guide to Choosing the Best Drill Bits for Hardened Steel Drilling through
” hardened steel can be a daunting task for even the most experienced DIY enthusiasts or professionals. This is because hardened steel is a dense and tough material that can quickly wear out ordinary drill bits, and even break them. That’s why it’s crucial to choose the right drill bits when working with hardened steel.
In this ultimate guide, we’ll take you through everything you need to know about choosing the best drill bits for hardened steel. We’ll cover the different types of drill bits available, their coatings, and the materials used to make them. We’ll also provide tips on how to drill through hardened steel effectively and safely, as well as things to consider when purchasing drill bits.
Firstly, it’s important to understand that there are two main types of drill bits for hardened steel: high-speed steel (HSS) and carbide-tipped. HSS drill bits are made from high-speed steel and are suitable for drilling through low to medium-hardness materials, while carbide-tipped bits are made from a combination of carbide and steel, making them ideal for drilling through harder materials like hardened steel.
When it comes to coatings, drill bits for hardened steel can be coated with materials such as titanium nitride (TiN), cobalt, or black oxide. These coatings enhance the durability of the drill bits and help them resist heat, wear, and corrosion.
Another factor to consider when choosing drill bits for hardened steel is their geometry. Drill bits with a 135-degree angle are generally more effective at drilling through hardened steel compared to those with a 118-degree angle.
In addition to the type of drill bit, coating, and geometry, other factors to consider when purchasing drill bits for hardened steel include the size of the drill bit, the shank size, and the length of the drill bit.
Drilling through hardened steel can be a challenging task, but with the right drill bits and techniques, it can be done effectively and safely. By following the tips and information provided in this guide, you’ll be able to choose the best drill bits for your needs and tackle even the toughest drilling tasks with ease.
