It boasts superior bending strength of 4700 MPa. Although it has a similar hardness as the T1, it replaced it as the industry standard. It includes drill bits, milling cutters, broaches, taps, twists, milling cutters, and knives. Widely regarded as the most popular industry-standard high-speed steel, M2 is suitable for different applications. M1 HSS drill bits are suitable for all cutting tools, including saw blades. However, hardening and quenching can increase hardness. Also, it flexes more but lacks the red-hardness features of the others. It’s softer compared to the others and more resistant to shock. Here are some of the characteristics of each molybdenum HSS.: However, their performances are somewhat similar. Group M HSS drill bits are cheaper in terms of production cost than the tungsten HSS drill bits. Molybdenum HSS drill bits are classified as Group M steels, ranging from M1 to M10. It includes high-speed molybdenum steels and high-speed tungsten steels. The hardness of a typical HSS drill bit is usually between 63-65 Rockwell “C” hardness.įigure 2: Different Types of Masonry for Woodwork and Metalwork Most of the best HSS drill bits are alloys made from a combination of tungsten, molybdenum, and chromium steel. Chapter 3 Best High-speed Drill Bits You Should Know It allows you to choose the required size, specification, design, and type of materials used based on your customers’ needs.ĭiamond tools manufacturing company like NC Cutting Tools gives you many options in making customized tools for cutting and drilling. While most of these HSS drill bits are readily available in the market, as a small or medium-sized saw blade supplier and distributor, it’s better to go for custom-made tools. However, let’s quickly examine the best drill bits for metal/steel.
We have identified those features that will enable you to make a pre-informed decision in the subsequent headings. There are several factors to consider before choosing drill bits. Chapter 2 What are the Best HSS Drill Bits for Metal/Steel? Thus, they are more durable and heat-resistant compared to many others. They can drill through hard metals and steel, as well as wood. These drill bits are sturdy and resistant to corrosion. High-speed drill bits are also titanium-made drill bits with a titanium oxide coating. Thus, high-speed steel drill bits are primarily used as metal cutting materials and made of high alloy tool steels.īesides, HSS is also a functional tool in the manufacturing industry due to its effectiveness in grinding. Unlike regular drill bits that cannot cut through steel materials, HSS drill bits seamlessly handle hard materials such as metals and steel. While each material is suitable for specific purposes, high-speed steel drill bits are in huge demand for many reasons. Others include tungsten carbide and polycrystalline diamond (PCD). Notable ones include soft low-carbon steel, high-carbon steel, cobalt-steel alloy, and high-speed steel (HSS). Many types of drill bits are available in the market based on the materials used in manufacturing them. How do I maintain my HSS drill bits?įigure 1: Close shot of drill bits Chapter 1 Why high-speed steel (HSS) Drill Bit? What are the different types of drill bits?

It is because of the suitability of that specific drill bit for other purposes. However, one must be cautious when choosing a particular drill bit for a project. While several varieties of drill bits are suitable for several different tasks, the type of drill bits varies considerably. From straight shanks to high-speed steels and carbide tips, there is an endless list of options for choosing a drill bit that is perfect for your steel or metals.
