Engineered for precision, these diamond bits provide a quick and clean way to drill through dense, abrasive materials like glazed ceramic and rock-hard porcelain. The ultra-durable welded-diamond tip and reverse spiral threads allow for higher speeds and continuous water cooling to prevent overheating.

• Ultra-durable welded-diamond tip outperforms and outlasts conventional masonry bits
• Reverse spiral threads deliver continuous water cooling for higher speeds and extended bit life
• Integrated core-ejection slot removes waste material, making it ideal for repetitive hole-boring
• Designed for precision drilling in dense materials including solid-body and glazed porcelain
