This 28 x 330mm diamond core bit is sized perfectly for common 22mm and 28mm copper pipework installations, making it an indispensable tool for heating and plumbing professionals. The extended 330mm length provides excellent reach for drilling through thick walls, cavity construction and multiple block courses where standard length bits would fall short. Featuring laser-welded diamond segments, this variant offers superior durability compared to brazed alternatives, ensuring consistent cutting performance throughout its service life. The 11mm hex connection provides universal compatibility with hex-drive drilling equipment, whilst the dry cutting design makes it ideal for site work where water supply for cooling isn't practical.
