The design details are practical for DIY work: a U-type slot helps with dust removal, and the 3-flat shank is made to hold more securely in your drill chuck for steadier drilling. It’s intended for use with electric or cordless hammer drills across a wide range of materials—just note the explicit limitation: it cannot be used on tempered glass (such as car glass).
For best results, the manufacturer recommends cooling with water and controlling speed while drilling, then drying and/or applying oil afterward to help prevent rust.
