About Core Drills
From installing sewage pipes and extraction fans to running cables, sometimes you just need to put a big hole in the nearest wall. That’s where the OnBuy collection of core drills comes in. Core drills have special, extra large drill bits that cut through material and extract a chunk of it for easy disposal, hence their name. We have many great core drills made by Makita, DeWalt and other popular manufacturers.
There are two main kinds of core drills, annular drills and diamond core drills. Annular drill bits have sharp cutting teeth and grooved flutes that pull chips and shavings out of the hole as it drills. They’re best for cutting through metal, as they produce burr-free holes. Diamond core drills are tougher than annular bits and will punch through solid concrete and other hardy materials with ease.
A dedicated core drill is ideal for professional work, but they’re a rather large and heavy tool, neither portable nor easy to store in your garage. So if you only need a core drill for a single product, these big machines may not be the best choice for you. Instead you should look to our collection of core drill bits! Fit one of these onto a compatible electric or cordless drill and you’ll have a core drill that’s well suited for small projects. As with the bits of our dedicated core drills, these detachable bits can be divided into annular or diamond core bits. These core drill bits can be combined with other drill bits and power tool accessories for a fully functional kit!
