Full Head Carbide vs. Normal SDS-Plus Hammer Drill Bits
When it comes to hammer drilling, not all SDS-Plus drill bits are created equal. Two popular types on the market are full head carbide SDS-Plus drill bits and normal SDS-Plus drill bits. Understanding their differences can help you choose the right tool for your project.
1. Material Construction
A full head carbide drill bit features a solid tungsten carbide tip that extends across the entire head, making it extremely robust and durable. In contrast, a normal drill bit has only a small carbide tip attached to a hardened steel head. This makes it lighter and more cost-effective but less durable in extreme conditions.

2. Durability and Lifespan
Full head carbide SDS-Plus hammer drill bits offer extreme durability and heat resistance, withstanding impacts from rebar and high heat. This extends their lifespan significantly compared to normal bits. By taking small bites through rebar, they reduce vibration and wear in a controlled way, keeping the bit intact for longer. Normal bits are better suited for standard masonry tasks such as bricks, soft concrete, and block walls, but under heavy use, their steel portion tends to wear faster.
3. Performance
Thanks to the full carbide design, these bits stay cool and keep the head intact, even under continuous heavy-duty drilling. They also provide faster drilling speeds and increased productivity, while features like a precision tip and optimized flute design ensure stability, accuracy, and efficient dust removal. In fact, their performance can be up to 3 times better than normal SDS-Plus bits. Normal bits, meanwhile, are ideal for occasional drilling and lighter tasks but may slow down when facing hard or reinforced concrete.
4. Cost Considerations
Full head carbide bits are more expensive due to their premium construction, but they are a worthwhile investment for professionals who need reliable performance in demanding environments. Normal bits are more affordable and perfect for DIYers or light-duty work.
Conclusion
Choosing the right drill bit depends on your project needs. For heavy-duty, professional drilling in hard or reinforced concrete, the full head carbide SDS-Plus drill bit is your best choice. For lighter, occasional masonry work, a normal SDS-Plus bit provides excellent value.
