- Tap drill bits are typically made from high-speed steel (HSS), which is a hard, wear-resistant material that can withstand high temperatures and pressures during cutting. Some tap drill bits are also available in carbide, which is an even harder material that provides superior wear resistance and longer tool life.
Molded fiberglass grating is manufactured in a one-piece construction process by interlacing pre-wetted glass reinforcing strands in a liquid resin matrix within a given configuration. Once the resin matrix has cured, the molded grid is removed from the mold. The one-piece construction ensures that all glass is impregnated with resin.
- The design of these drill rods is a testament to engineering ingenuity. They are designed to withstand the immense pressure and friction generated during drilling, while also being flexible enough to navigate the complex geological formations that coal mines often encounter. The surface treatment, often involving heat treatment and anti-corrosion coatings, enhances their durability and resistance against wear and tear, ensuring a longer service life.
- Another significant benefit is their lightweight nature. Plastic gratings weigh significantly less than their metal counterparts, which not only simplifies transportation and handling but also reduces the structural requirements for installation. This translates to lower overall costs and easier maintenance, as they can be easily replaced or repaired without heavy lifting equipment.
