Pultrusion is a continuous manufacturing process where reinforcement materials, primarily glass fibers, are pulled through a resin bath, then heated and formed into the desired shape. The result is a strong, lightweight, and corrosion-resistant grating that offers numerous advantages over traditional materials like steel or concrete. Rotary hammer drill bits differ significantly from conventional drill bits due to their unique design and mechanism. They are engineered to not only rotate but also reciprocate axially, providing a hammering action that penetrates hard materials with ease. This dual-action system, known as percussion drilling, makes rotary hammer drill bits indispensable in construction and DIY projects.
