Rock Hard Toolz diamond hard tips are designed to bore through abrasive, dense tiles. The tips smoothly drill through glazed porcelain, ceramics, and solid-body porcelain. Our bits operate at high speeds due to their reverse-spiral threads that allow continuous water cooling in order to drill quickly and cleanly. Plugged material and other drilling debris is easily removed via ejection to be able to make repeated cuts without the hassle of slowing down.
• Use in rotary drilling only with water lubrication.
• Excellent for drilling:
– Terra Cotta
– Tiles (up to 5th Class)
