- 20. Self-feed hammer drill bits Ideal for wood drilling, they have a built-in screw thread that helps pull the bit into the material, speeding up the process.
- However, despite its numerous benefits, the adoption of FRP housing is still in its nascent stage. Challenges like high initial costs and lack of widespread awareness need to be addressed. As research and development continue, it is expected that these hurdles will be overcome, leading to a more widespread use of FRP in residential and commercial construction.
- Traditionally, drill rods were made from steel, which was strong but heavy and prone to wear and tear. This limited their reach and required frequent replacement, leading to increased downtime and costs. However, with the development of advanced materials like high-strength alloys and carbon fiber composites, mine extension drill rods have become lighter, stronger, and more durable.
