In various engineering support scenarios, a high-efficiency and durable rock bolt drill bit is the key tool to ensure construction safety and quality. Our 28mm full piece rock bolt drill bit, with its outstanding performance and exquisite craftsmanship, has become the top choice for many engineering projects.

Product Features

• High-quality Material: Made of high-strength alloy steel and treated with special heat treatment processes, it boasts excellent wear resistance and impact resistance. This ensures the drill bit can withstand the harsh conditions of rock drilling and maintain its sharpness and strength throughout the drilling process, even in hard rock formations.
• Full Piece Design: The full piece design provides a larger cutting area and stronger overall structure. It enhances the stability and accuracy of drilling, reducing the risk of drill bit breakage and deviation. This design also allows for more efficient chip removal, preventing blockages and ensuring smooth drilling operations.
• Precise Dimension: With a precise 28mm diameter, it meets the standard requirements for rock bolt holes in most engineering applications. The accurate size ensures a tight fit with the rock bolts, maximizing the anchoring effect and providing reliable support for structures such as tunnel linings, slope reinforcements, and foundation pits.
• Versatile Applications: Widely used in coal mine support, tunnel construction, hydropower projects, transportation engineering, and other fields. Whether it’s for roof bolting in coal mines, tunnel excavation support, slope stabilization in hydropower stations, or road and railway infrastructure projects, this drill bit can handle a variety of drilling tasks with ease.
• Long Service Life: Thanks to its durable material and robust design, the 28mm full piece rock bolt drill bit has a significantly longer service life compared to other similar products. This not only reduces the frequency of drill bit replacements but also lowers the overall construction costs, making it a cost-effective solution for long-term engineering projects.
