  • It’s no surprise to hear that drill bits come in all shapes and sizes. 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. If you’re drilling a hard metal then you’ll need a large tip angle. The right type of tip angle will also ensure that “walking” or “wandering” doesn’t occur – when the drill bit slips across the metal. - Source: Internet

Versatile application: We can use most cobalt drill sets with almost any electric tool. They come with bits of different sizes that fit securely in the power tool so that they don’t spin or twist when drilling hard things. We can also use them to drill through plastic, wood, most metals, and even rough surfaces. - Source: Internet

  • The next thing is to make sure you are using them properly. Unlike drilling soft materials like wood, plastic, etc. There are a few things to be aware of when drilling metal. - Source: Internet
  • Another important thing is that titanium ultimately loses its titanium coating. Even after sharpening the bit, you will only have a high-speed steel bit. Thus, after sharpening the titanium drill bit, it also loses its titanium cutting edge. But the advantage of having a cobalt drill bit is it can retain the cobalt alloy after re-sharpening. So you will have long-lasting quality service using cobalt alloy bits, making it a much better and worthwhile investment over titanium drill bits. - Source: Internet
  • Without a pilot point, to drill a large hole accurately, you’ll often drill a “pilot hole”. This is done by using a smaller drill first, which is less susceptible to drift.

Both of these metal drill bits are coated in extra-hard materials and have a split point that prevents wandering. - Source: Internet
  • Titanium blades have a coating. Over time, this coating will wear off. When the coating is completely gone, the bit would have lost much of its heat resistance. This is a problem when you’re drilling metal since metal-on-metal can get very hot, very fast. - Source: Internet
