Diamond-coated bits provide clean holes in hard materials, including tiles, porcelain, granite, and marble. The built-in wax cooling feature supports dry drilling by reducing heat buildup and preserving bit life.
SHDIATOOL 1-1/2 Inch Diamond Core Drill Bits
SHDIATOOL core bits are designed for drilling hard stone, concrete, granite, and brick, with a 38mm diameter and a dry/wet drilling option. Built with high-quality diamond and a robust steel body, these bits offer extended life and efficient performance for larger holes, such as faucet mounting or plumbing through stone countertops.

A 1/4-inch hex shank provides secure grip in most drills, enabling reliable dry or wet drilling on ceramic, tile, glass, granite, marble, brick, and stone.
Buying Guide
Key considerations when choosing granite drill bits include material type, drilling method, and hole size requirements. Diamond-coated bits are typically best for hard stones such as granite and porcelain, offering greater wear resistance and cleaner cuts. Dry drilling options reduce mess but can generate more heat; many sets include wax lubrication or call for water cooling to prolong bit life. Shank type matters: hex shanks fit quick-change chucks for faster bit switching, while round shanks may require a traditional chuck.
Size range is another factor. If you regularly drill countertop sinks or faucet holes, a kit with larger diameters (up to 1/2″ or 12mm) is practical. For tile fabrication or glasswork, look for smaller sizes (4mm–8mm) with precise, vacuum-brazed diamonds. Durability indicators include the number of uses per bit and the bit’s ability to maintain a clean edge under high RPM. Finally, consider whether a storage case is included for organized, long-term use.
Summary: The chosen sets provide a mix of dry and wet drilling options, diverse size ranges, and robust diamond technology suitable for granite, ceramic, tile, and other hard materials. Each product emphasizes clean hole quality, heat management, and tool life, helping users select a kit aligned with their project scale and material hardness.
