Protects your drill: Your fingers, eyes, and face aren't the only things that will be damaged by a dull drilling bit. It's also a waste, as you're stuck having to travel out and buy new bits. Reduces the prospect that the bits will break: A broken drilling bit can quickly become a projectile if it snaps mid-drilling. An equivalent is real of drill bits - the duller they're, the more likely they're to cause injury.
COBALT DRILL BITS PROFESSIONAL
Reduces the danger of injury: There's a proverb in professional kitchens: Dull knives cut fingers. If you're wondering why to sharpen drill bits instead of allowing them to be or replace them, here are a couple of reasons. Unlike a replacement car, it's relatively easy to revive a drilling bit to its original sharpness. Just like a replacement car, a drilling bit starts to wear out the minute you begin using it. If you've got a bench grinder, you'll sharpen the bits on your own. But after a short time, the leading edge becomes dull and needs to sharpen. Cobalt drill bits have a high resistance to heat, making them perfect for repeated use. Counting on the task and whether you're drilling through wood, steel, iron, or titanium, the drill bits are available in a spread of sizes and angle points. It would be best if you had a pointy Cobalt drilling bit to form the cutting easier and, therefore, the holes are perfect. Some cobalt drill bits can even withstand temperatures up to 1,100 degrees Fahrenheit. They are made with a small percentage of cobalt fused with hot-work steel these bits are naturally more robust and more heat-resistant than typical drill bits due to the cobalt's infusion. You could even use them to drill through hardened steel.Cobalt drill bits are the best option for the most robust materials for a custom steel project. Not only did it offer 29 drill bits in varying sizes, but these heavy duty drill parts could handle even the toughest metals. What we found from our list, was that the Irwin Index Drill Bit Set was our favourite and a good all-rounder. Everyone has their own need when it comes to drilling.
Also, do you want to maximise the life of your drill bits? If the answer is yes then it’s best to use a cutting oil as this acts as a coolant and lubricant as well as preventing corrosion.īuying the perfect cobalt drill bit often comes down to personal preference. Firstly, what are you drilling? If you’re drilling wood or plastic then you’re not going to need a cutting oil. The question of whether you need to use a cutting oil every single time you use your drill bit is depending on several factors. A cutting oil can also make drilling a lot easier, and not only that but it can make your drill bits last longer too and greatly increase their lifespan. The benefits of using a cutting oil do not end there either. Cutting oil serves an important purpose in that it lubricates the drill bit to reduce the friction and heat build up which is inevitable when it comes to drilling. When drilling metals often a cutting oil is needed. Q: Is it really necessary to use cutting oil every time I use my drill bit? The right type of tip angle will also ensure that “walking” or “wandering” doesn’t occur – when the drill bit slips across the metal. If you’re drilling a hard metal then you’ll need a large tip angle. But did you know that this can greatly affect the actual usage of the drill? The tip angle will vary across the drill bit market but generally speaking they are available in 90 degree, 120 degree, 135 degree, 140 degree and 145 degree angles. It’s no surprise to hear that drill bits come in all shapes and sizes. Will you be needing all the different sizes? Does the kit have the size that you’re likely to be using most? Most cobalt drill bit sets include a variety of drill bits in different sizes. What type of materials will you be mostly drilling? Do you use a high-speed drill? Know your drill before you invest in new cobalt drill pieces and don’t forget to check the product specifications extensively before you buy. They can often be used for other materials too but are generally more hard-wearing and suitable for metals. This might seem like an obvious thing to consider, but do you really need extra strength cobalt drill bits? Cobalt drill bits are generally used to drill ferrous and non-ferrous metals and stainless steel.
