KITPIPI Diamond Core Drill Bits – Precision Dry Drilling for Hard Surfaces

Tackle the toughest tiling and stone drilling jobs with confidence. These KITPIPI Diamond Core Drill Bits are engineered with advanced brazed technology to cut through ceramic tile, granite, marble, glass, and more — cleanly, quickly, and without water. Whether you're a seasoned tradesperson or a dedicated DIYer, these bits deliver professional-grade results every time.

Made in Mainland China.

Key Features

• Advanced Brazed Technology: Each bit functions as both a drill and a grinder, providing dual-purpose performance for drilling and edge finishing in a single tool.
• No Water Required: Specially designed for completely dry drilling — no coolant setup needed. Built-in cooling wax melts during operation to lubricate and dissipate heat at the contact point, protecting both the bit and your workpiece.
• High-Grade Abrasive Construction: Premium diamond abrasive material ensures exceptional resistance to strong impacts and long-lasting sharpness, even on the hardest surfaces.
• Multiple Diameters Available: Choose from 6mm (0.24"), 8mm (0.31"), 10mm (0.39"), and 12mm (0.47") to suit a wide range of applications.
• Fast, Clean Holes: Penetrates marble, ceramics, glass, red brick, and microcrystalline stone in seconds, leaving smooth, perfectly circular holes with no chipping.
• Hexagonal Shank Design: The hex shank ensures a secure, slip-free fit in standard power drills and drill presses for maximum control and accuracy.
• Multi-Function Use: Beyond hole drilling, these bits excel at edge grinding, trimming, and surface refinement — a true all-in-one masonry tool.
• CE Certified: Meets European safety and performance standards for your peace of mind.

Frequently Asked Questions

Q: Can these diamond core drill bits be used without water for cooling?

A: Yes! These bits are specifically designed for dry drilling. Each bit contains an internal cooling wax that melts during use, providing built-in lubrication and heat dissipation. This eliminates the need for water or external coolant while protecting the bit and your material from overheating.

Q: What type of drill is compatible with these diamond core bits?

A: These bits feature a standard hexagonal (hex) shank that fits most common power drills, cordless drills, and drill presses. The hex shank prevents slipping for a secure, precise connection during use.

Q: Are these bits suitable for drilling through porcelain tile?

A: Absolutely. The high-grade diamond abrasive construction makes these bits ideal for drilling through porcelain, ceramic tile, granite, marble, glass, and other hard masonry materials. They create smooth, chip-free circular holes within seconds.

Q: How long do diamond core drill bits last?

A: Longevity depends on the material being drilled and the technique used. The integrated cooling wax and premium abrasive material significantly extend the operational life of these bits compared to standard alternatives. Avoiding excessive pressure and allowing the bit to work at its own pace will maximize lifespan.
