Draak 4mm Hard Tile Porcelain And Granite Drill Bit

Draak hard tile drill bit has been designed specifically for use on porcelain and other types of hard tiles. It also performs equally well on granite, marble and hard bricks including engineering brick.

This includes a unique triangular shank which prevents the bit spinning in the chuck as well a special flute which ensures maximum spoil extraction. The design of the flute also enables the bit to remain cool without the need for water cooling.

• Bit tips have been ground using diamond tools to leave a highly accurate 95° angle.
• Copper brazed tip ensuring that there is no tip loss even when drilling the hardest of tiles.
• To achieve best results, Draak hard tile drill bits should be used with a cordless drill driver with a variable speed trigger on a very slow speed with maximum pressure. They should not be used on the hammer action.
