Diamond Core Drill Bit Set, 8 PCS 6/8/10/13/19/25/32/50mm Diamond Hole Saw Kit, with Finger Milling Bit Saw Blade and Storage Case, for Dry and Wet, Diamond Drill Bits for Ceramic Tile

Our diamond core drill bit set features a high-quality diamond sand coating at the tip and utilizes advanced vacuum brazing technology. It can withstand high temperatures and remains unbreakable while delivering sharp, high-precision, and smooth cutting at high speeds.

Our diamond hole saw kit includes 8 different sizes of drill bits, a 0.8 in/20 mm finger drill bit, a 5/8"-11 connector (hex shank), and a 4.5 in/115 mm saw blade. This allows for professional and precise hole drilling. Plus, it comes with a toolbox for easy portability.

In dry-cutting mode, you'll experience unmatched cutting speed and chip removal, significantly enhancing work efficiency. In wet-cutting mode, the diamond drill bits showcase durability, ensuring a longer lifespan with less dust.

Once the diamond drill bit is securely fixed, place it at a 15-45° angle to reduce initial resistance, making cutting easier. When the hole begins to take shape, bring it to a vertical position for smoother and more precise cutting.

The tile hole saw kit ensures clean and accurate holes in hard materials like tiles, granite, marble, other stones, and ceramics.
