This collection features high-performance diamond core drill bits designed for professional tile installers. These tools provide smooth cutting action, long-lasting durability, and reliable performance across a wide range of applications.
What Are Diamond Core Drill Bits Used For?
Diamond core drill bits are used to drill holes in hard materials where standard drill bits cannot perform effectively. They are commonly used for:
- plumbing pipe penetrations
- shower valve and fixture installations

The diamond cutting surface allows for efficient drilling while reducing heat buildup and minimizing edge damage.
Wet vs Dry Core Drill Bits
Depending on your application, diamond core drill bits can be used wet or dry:
- Wet drilling: Helps reduce heat and extend bit life
- Dry drilling: More convenient for jobsite flexibility
Always follow manufacturer recommendations for best performance and durability.
