plug hole drill rod with hex 19 x 108 mm shank for marble

Features of plug hole drill rod

1. Integral Forged Structure

   The plug hole drill rod adopts an integral design, forging the rod and the chisel head into one piece. This eliminates threaded connections, which are weak points in traditional drill rods, ensuring efficient energy transmission and preventing connection failures.

2. Hex 19x108mm Shank, Reliable Transmission

   This plug hole drill rod uses a standard Hex 19x108mm shank, ensuring a secure fit with handheld rock drills such as Y6, Y24, and YT28. It guarantees strong torque transmission with zero rotational slippage.

3. Tungsten Carbide Chisel Bit

   The plug hole drill rod features a high-grade tungsten carbide chisel tip, capable of drilling straight and clean holes in soft to medium-hard rocks such as limestone, sandstone, and marble. It is especially suitable for plug hole drilling and shallow blasting in quarries.

4. Full-Length Carburized Heat Treatment

   The plug hole drill rod undergoes advanced surface carburizing, giving it a surface hardness of 58HRC to 62HRC while maintaining toughness and impact resistance in the core. This significantly extends service life in highly abrasive quarry environments.

5. Optimized for Plug Hole and Shallow Hole Drilling

   The plug hole drill rod is specially designed for plug-and-feather stone splitting, plug hole drilling, and shallow blasting in granite, marble, and limestone quarries.
