- Tungsten Carbide Steel: Tungsten carbide steel drill bits are the most durable and heat-resistant drill bits available, making them ideal for drilling through the hardest materials like masonry.
Drill Bit Treatments and Coatings
Drill bits can be treated or coated with additional materials to improve their performance. Some of the most common treatments and coatings include:
- Titanium Nitride (TiN): TiN coating increases the surface hardness and durability of drill bits.
