SDS Drill Bits Suitable for Metal Do Exist
For example, Bosch’s GSB120 Dual-Power Impact Drill is a high-performance household tool suitable for various daily repair and assembly tasks. Equipped with a 12V battery system, it delivers 30Nm of hard torque and 14Nm of soft torque, making it capable of drilling and screwdriving in different materials. Its maximum drilling diameter reaches 20mm (wood) and 10mm (metal), meeting most home improvement needs. Additionally, other brands also offer SDS drill bits suitable for metal materials. For specific models and performance details, refer to product descriptions or consult professional tool suppliers.
A Guide to Hammer Drill Bit Models for Easy Selection
1. SDS Drill Bits
SDS drill bits, also known as professional SDS bits, feature a right-angle triangular prism-shaped shank and are used with SDS-compatible chucks, making them ideal for rotary hammers and impact drills. They offer superior wear resistance, durability, and drilling quality compared to standard bits.
2. SDS-Plus Drill Bits
An improved version of SDS bits, SDS-Plus bits are longer and better at dampening vibrations, especially noticeable in rock drilling. The “Plus” designation indicates an enhanced design for deeper drilling.
3. SDS-Max Drill Bits
Larger than SDS-Plus, SDS-Max bits are designed for heavy-duty rotary hammers in large-scale construction. They can drill up to 20 inches deep, making them increasingly popular for industrial applications.
4. SDS-Top Drill Bits
Designed for moderate-quality materials with lower performance demands, SDS-Top bits are shorter than standard SDS bits and typically used for smaller-diameter holes.
5. Round Shank Drill Bits
These do not require a specialized chuck and can be used with standard 3-jaw chucks. Commonly used for general drilling, they typically support diameters up to 5/8 inches.
6. Hex Shank Drill Bits
These require a dedicated hex chuck and are used for drilling in wood, metal, and softer materials. Unlike SDS or standard bits, they do not require hammering or vibration.
7. Triangle Shank Drill Bits
Specialized for tiles and stone, these bits often require a specialized chuck for better cutting performance when working with ceramics.
The above are common hammer drill bit types, each suited for different materials. Choosing the right model for your needs is crucial.
