DiskMaker X is a tool that allows you to create a bootable disk using the official OS X installer (the one you can download from the Mac App Store). It will detect the OS X Install Program with Spotlight and then create a bootable installation disk. It is the easiest way to create an OS X installer in just a few clicks. You can then use the Install drive to reinstall the OS on a newly formatted drive or install it on multiple Macs without having to re-download the entire installer.
