Shank Adapter

Key Features of Shank Adapters for Rock Drilling Tools

1. Material and Durability:

● Made from high-strength alloy steels or tungsten carbide to endure high stress, abrasion, and impact.

● Heat-treated for enhanced hardness and toughness to prolong service life.

2. Compatibility:

● Designed to fit specific types of rock drill bits (e.g., button bits, cross bits, or chisel bits) and drilling equipment (e.g., hydraulic or pneumatic rock drills).

● Available in various shank types, such as hexagonal, round, or spline shanks, to match different drilling machines.

3. Precision Engineering:

● Manufactured to tight tolerances to ensure a secure fit between the drill bit and the drilling rod or chuck.

● Minimizes vibration and energy loss, improving drilling efficiency.

4. Threaded or Tapered Connections:

● Many shank adapters feature threaded or tapered connections to securely attach the drill bit to the drill rod or chuck.

● Common thread types include R-threads, T-threads, and API threads.

5. Shock Absorption:

● Some adapters are designed with shock-absorbing features to reduce stress on the drilling equipment and extend the life of both the adapter and the drill bit.

Applications of Shank Adapters in Rock Drilling

● Mining: Used in underground and surface mining for drilling blast holes or exploration.

● Construction: Employed in foundation drilling, tunneling, and road construction.

● Quarrying: Used to extract stone and other materials from quarries.

● Geotechnical Drilling: Used in soil and rock sampling for geological surveys.
