Diamond Drill Bits 22x370mm Fast Drilling Tool for Brick

【Concentric Shaft】 The anti-deviation concentric shaft centers precisely on brick and concrete from the start, preventing the bit from drifting across surfaces and ensuring a clean, accurate hole placement every time. 【Diamond Edge】 The sintered diamond powder edge, with high-quality diamond grains fused directly onto the seamless steel body, provides aggressive cutting action through hard structures without clogging or vitrification. 【Steel Tube】 The seamless steel tube construction, with a rigid one-piece body, resists bending or deformation under high torque loads, maintaining balanced rotation for smoother operation and less vibration. 【Quick Compatibility】 Quick-change compatibility, thanks to a standardized shank, fits a wide range of handheld and drill press power tools, allowing for fast bit changes for a streamlined workflow. uninterrupted.
【Deep Profile】 The 22x370 mm deep profile, with an extended length of 370 mm, passes through thick walls and foundations in a single pass, eliminating the need for pilot holes or repetitive chiseling movements.
