Bullet Teeth Holder
Reliable, durable, and precision-engineered—designed to maximize drilling efficiency and extend tool life in the toughest conditions.
Introduction
Bullet teeth holders are essential components of a complete bullet teeth system, also known as round shank chisels. They play a critical role in rotary rock drilling buckets, core barrels, and rock augers. During piling operations, the drilling teeth make first contact with rock or soil, cutting through the material before the piling tools extract the debris.
The durability and wear resistance of drilling teeth directly impact piling efficiency. Selecting the right drill bits is crucial for optimal performance. Common drilling teeth models include B47K17.5H, B47K19H, B47K22H, C31, and more, while compatible holders include B85-2, B85, B43H, C30, etc. Choosing the appropriate combination based on ground conditions is essential, and Siderwin is available to provide professional guidance.
Application
Bullet teeth holders are used in combination with bullet teeth for rock drilling buckets, core barrels, and rock augers in foundation bored pile projects. These rotary piling tools, equipped with bullet teeth, are suitable for breaking and loosening water-bearing cohesive and non-cohesive soils, as well as cutting through medium to strongly weathered rock layers and hard bedrock.
