Description

HENGLONG Drill Furnace tapping drill bit with high quality which ensure the efficiency and service life of your blast furnace and ferro-alloy applicaton equipment. HLDRILL select special materials and manufacturing processes to suit the machines performance and thereby enhance stability and reliability. Our individually selected material qualities ensure low wear and ultimately have a direct impact on the economic efficiency of the whole plant.
Furnace tapping drill bit shape and material (carbide or heat resistant Cr-Ni alloy tips) are important. The ability to retain a sharp cutting edge to cut, rather than hammer, through the tap hole mass, is important with the bit cutting face presented to a debris and dust free face to drill. Drill bit diameter is usually controlled within a range of 33 mm to 65 mm. Where hammering is considered important, an inside bit face that is totally flat, to maximize transmission of impact energy coupled with transition from spherical to semi-spherical carbide shapes is used. Air scavenging is typically used to achieve a cleared hole, additionally providing some cooling of the drill bit to help prolong its life.
