Vacuum Brazed Construction Core Drill Bit
product introduction
The Construction Core Drill Bit from Xingong is engineered for enhanced durability and performance in core drilling applications. Utilizing advanced vacuum brazing technology, diamonds are integrated into the steel body, significantly increasing the drill bit's strength and lifespan while enabling faster drilling speeds. This bit is ideal for drilling concrete, masonry, block, and brick.
product advantage
• Enhanced Strength and Longevity: Diamonds are vacuum brazed onto the steel body, becoming an integral part of the bit. This process increases the strength of the drill bit and extends its lifespan.
• Faster Drilling Speed: The advanced design and high diamond concentration allow for significantly faster core drilling, improving overall efficiency.
• Versatile Use: Specifically designed for concrete, masonry, block, and brick. While wet use is suggested for optimal performance, it can also perform under dry conditions with a reduced lifespan.
• Tube Length Options: Available in various tube lengths, up to 14 inches, to accommodate different drilling needs and project requirements.
