With seven thoughtfully chosen sizes, this kit covers common drilling needs from light upgrades to more demanding installations, helping you work efficiently without swapping bits mid-project.

Smart design for long-lasting performance

• Wax-lubricated interior minimizes diamond loss and helps extend bit life, while an integrated coolant system keeps heat in check for steadier operation.
• For optimal results, pause after each hole to allow cooling, preserving bit integrity during longer sessions.

Clean, precise holes you can rely on

• Vacuum brazed diamond technology delivers accurate, smooth drilling through tile, porcelain, granite, ceramic, glass, marble, and masonry brick.
• Side flute geometry clears debris quickly and the depth marker supports consistent drilling depth for repeatable results.

Easy to use with common tools

The round shank fits most popular electric drills, angle grinders, and benchtop drills, making it versatile for DIY projects and professional work alike. A heavy-duty storage case keeps bits organized and protected, and DECKRKAT support is available if you need guidance.
