Choosing the Right Drill Bits for Tough Steel Jobs
Steel is a popular and versatile metal used in thousands of products from cars to construction equipment. But working with steel requires the use of strong and durable drill bits. Whether you are a DIY enthusiast or a professional, selecting the right drill bits for steel can be tricky. There are many factors to consider, including size, shape, and materials. In this article, we will discuss some essential tips to help you choose the right drill bits for steel.
Tip #1 – Consider the Type of Steel You’re Drilling
Not all steel is created equal. Some are tougher and harder to drill than others. For example, you will need a more robust and durable drill bit to drill through hardened steel than mild steel. Knowing the type of steel you’re working with can help you choose the correct type of bit and increase your chance of success.
Tip #2 – Select the Right Size
Selecting the correct size bit for drilling steel is vital. Choosing a too-small bit will make it hard to make the hole, while a too-large bit will render an oversized hole. To get the right size of the drill bits for steel, measure the diameter of the hole needed, then select a bit that’s 1/64 inch larger than the hole required.
Tip #3 – Check the Material
Different types of drill bits are made from different materials, including carbon steel, high-speed steel, cobalt, and titanium. Carbon steel bits are ideal for softer metals, while high-speed steel is excellent for tougher metals like steel. Cobalt bits have a higher resistance to heat and can perform well on exceptionally durable steel. Titanium bits can handle high-temperature jobs and have a longer lifespan than many other types of drill bits. Ensure that you choose the proper drill bit material to match the type of steel you intend to work on.
Tip #4 – Consider the Angle
Drill bits for steel come in various angles, including 118 degrees and 135 degrees. A 118-degree angle is suitable for softer metals while 135-degree angles are ideal for harder metals like steel. Be sure to choose the correct angle to prevent damaging the metal and the drill bit.
Tip #5 – Choose Between Twist Bits or Hole Saw Bits
Twist bits are the most common drill bits for steel used because of their versatility. They are most suitable for making small holes through the metal. Hole saw bits, on the other hand, are ideal when drilling a larger-sized hole. Hole saw bits are safer to use and need less pressure when drilling, reducing the risk of breaking the drill bit.
Tip #6 – Consider a Drill Bit Set
If you are working on several projects that require different hole sizes, consider investing in a drill bit set. A drill bit set typically contains a range of bit sizes that are suitable for different applications, including drilling through steel. A drill bit set can save you both time and money in the long run.
Selecting the right drill bits for steel is essential for a successful and safe drilling project. Considering factors such as the type of steel, the size of the hole required, and the angle of the bits will increase your chances of success. Don’t forget to select the proper material and choose between twist bits or hole saw bits. And, if needed, invest in a drill bit set for maximum flexibility on your projects. With the right drill bit, you can make precise and clean holes in tough steel surfaces with ease.
