The best drill bits for drilling through stone depend on the specific material and application, but key recommendations include:
- Diamond Drill Bits: These are highly recommended for natural stone, as diamond is one of the few materials capable of cutting through such hard surfaces efficiently .
- Tungsten Carbide-Tipped (TCT) Masonry Bits: Ideal for hard rocks like granite, these bits offer durability and longevity, especially when used with hammer drills or SDS drills .
- SDS Max Natural Stone Drill Bits: Designed for heavy-duty use, these bits feature tungsten carbide tips and a 4-flute design for efficient dust removal, making them suitable for stone and granite .
For tools, SDS drills or drills with hammer mode are preferred, as they provide the necessary impact force for hard materials . Avoid standard hammer drills for extremely hard stone, as they may lack sufficient power .
Always match the bit type to the stone hardness and use appropriate drilling techniques (e.g., low speeds for tiles) .
