Drill bits made from glass diamonds are necessary tools for a craftsman whose work involves the use of tough materials. They are constructed in a fashion that facilitates the drilling functions without altering the surface in any way. Thanks to the diamond coating around the drill bits, their cutting capabilities have been enhanced further and thus can be used by both professional contractors and even those who prefer DIY work. Beijing DEYI Diamond Products strives to offer the best quality and cutting edge innovations to enable our customers and power drill drivers that will be performing in a wide range of operations.
