The 6mm Needle D's Diamond Drill Bit is built for fast, precise drilling through porcelain, ceramic, glass and stone using a standard drill or impact driver.
Its compact 6mm diameter is ideal for anchors, small fixtures and detailed installation work where accuracy matters.
The 1/4" hex shank makes it quick to chuck up and get to work, while the diamond cutting edge handles the hard materials conventional drill bits weren't made for.
