If you’re a newbie, it’s good that you’re reading this article. There is a plethora of things to consider when shopping for drill-bits.
As drill bits are so small, you’ll be astonished that they can be found in multiple types of metals and materials. The most common option would be carbon steels. Low carbon steels are more affordable than high carbon counterparts. However, they require more maintenance.
Just know that high-carbon steels can pierce through very tough materials, while their counterpart works with softer materials like plastics.
High-Speed Steel or HSS drill bits also exist. They can handle tough materials and are resistant to heat, so they can last a long time. A HSS variant is Cobalt HSCO. They’re more durable yet are brittle.
If you’re not going to be working with metal, and exclusively need to pierce through ceramic, stones or tiles, you might want a diamond drill bit. You’d think they’d be pricey due to the diamond in their name but this isn’t the case.
Not only can you get drill bits in multiple materials, but they come with all kinds of coatings too. The coatings influence how protected the items would be – they reduce friction and stress. They can be added on in multiple ways. The best would be thermal spray; they won’t go anywhere.
From the coatings available, cobalt is the superior choice. It can handle very high temperatures. If you have to pierce through a very hard material, you’ll be dealing with a lot of heat. By switching to a cobalt sprayed drill bit, you’d be able to get the job done.
You can get options coated in zirconium too. They wouldn’t look as good as cobalt choices. However, the metal strengthens brittle materials like steel.
There are so many types of specific drill bits. Make note of what material you’re going to be piercing into. This’d help you get something exactly for your project. To name some of the drill bits around; twist drill, plug cutter, hole saw, masonry, and tile drill bits exist.
Twist drill options are the most common. They can be used around the house and are used for general purposes. Meanwhile, a plug cutter specifically bores into wood and creates plugs for fasteners. Tile drill bits can pierce into tiles without cracking them, and masonry bits can bore through concrete and brick with ease.
If you’re thinking of getting a masonry drill bit, it would most likely be a diamond option we mentioned earlier.
Drill Point Length
How precise of a cut do you need to make? If you need to make a very accurate cut, a shorter drill point would be needed. These options tend to be sturdier as well.
The type of drill bit you’d get would affect the quality and type of cut you’d be able to make. As mentioned, not all of them would work on each project. You need to be mindful of the material you’ll be working with when shopping.
