The titanium makes the bit much harder and is slightly self-lubricating, which makes it perfect for drilling hard metals. They’re easily recognisable as they have a gold-coloured coating. Titanium bits look like twist bits, but they’re coated in a titanium alloy. They’re made using special alloys which helps them resist temperatures of up to 500☌, which is especially useful when drilling harder metals! HSS bits are a little tougher and can drill through harder materials quicker and without blunting. High-Speed Steel (HSS) Bits – All-Round Drill Bits For drilling through these hard surfaces, you’ll probably want a harder drill bit to match. Blunt bits can snag as they bore through materials, leading to ragged holes and splits. They’re good for drilling wood or plastic, and while they can be used to drill through harder materials like brick or metal, they will blunt quite quickly. Steel bits are the softest, cheapest bits you can find. Steel Drill Bits – Best for Wood and Plastic You use twist bits to drill holes in flat surfaces, but depending on the material you’re drilling (metal, wood, brickwork, etc) you’ll need a slightly different twist drill to get the job done right.
They’re easy to recognise thanks to their corkscrew-like groove.
Most standard drills will usually come with a few differently-sized twist drill bits. Twist bits are the most common kind of drill bit. A specialist drill bit can offer more power, more precision, and a cleaner hole depending on what you’re drilling. Most cordless drills come with a few basic drill bits anyway, but for some DIY jobs, you might need something extra. You’ll need a drill to do even the most basic DIY jobs around the house, whether it’s putting up a shelf or installing a light fitting. This goes double for when you’re using a drill! As you might imagine, drilling holes around your home without the knowledge or tools to do it properly can get messy pretty quickly. When it comes to DIY, it’s important that you have the right tools for the job. Which Drill Bits Should I Use? Your Complete Guide to Drill and Screwdriver Bits
