Drilling a hole in steel is not an easy task. To do it right, you need the right tools. The most important tool you need is a high-quality drill bit. When it comes to drilling steel, not all drill bits are created equal. Some will do the job, but not perfectly, while others will make drilling a hole in steel feel like a breeze. In this article, we’ll take a look at some of the best drill bits for steel.
The first thing to consider when purchasing drill bits for steel is the material they’re made from. Generally, high-speed steel HSS drill bits are the most common type of drill bits used for drilling steel. They are made from a type of steel that is highly resistant to wear and heat and can maintain their sharpness even after prolonged use.
If you’re looking for a drill bit that can handle even tougher materials than steel, a cobalt drill bit might be what you need. Cobalt drill bits are made using a blend of cobalt and steel, which gives them a higher resistance to heat and wear than normal HSS drill bits. They’re perfect for drilling through harder types of steel and other materials like stainless steel and titanium.
Another important factor to consider when purchasing drill bits for steel is the point angle. The point angle refers to the angle of the tip of the drill bit and is an important factor in determining the type of material the bit can handle. For drilling into steel, a point angle of 135 degrees is recommended. This allows the bit to cut through the steel efficiently without dulling or breaking.
When it comes to choosing the right size drill bit for the job, it’s important to remember that a larger bit may not necessarily be better. In fact, using a bit that is too large for the job can cause the bit to overheat and dull, making the job even harder. It’s best to choose a bit that’s the right size for the hole you need to drill.
One of the most important things to remember when using drill bits for steel is to keep them cool. Drilling through steel can generate a lot of heat, which can cause the bit to overheat and dull. To prevent this from happening, it’s important to use coolant or lubricant while drilling. This will help keep the bit cool and ensure that it can maintain its sharpness for longer.
If you’re looking for a drill bit that can handle a wide range of materials in addition to steel, a multi-material drill bit might be the right choice for you. These bits are made using a special blend of metals that make them more versatile than normal drill bits. They can handle materials like wood, plastic, and even masonry, in addition to steel.
Finally, it’s important to remember to take the right safety precautions when using drill bits for steel. Always wear eye protection and gloves to protect your hands from sharp metal shards. Additionally, make sure to use the drill bit correctly and follow all instructions carefully.
Drilling a hole in steel requires the right tools and the right preparation. By choosing high-quality drill bits made from the right materials and with the right point angle, you can make the job much easier. Remember to keep the bit cool and to choose the right size drill bit for the job. With the right drill bit and the right approach, drilling through steel can be a breeze.
