Tap hole drill bit Hoogovens

solidmulti-purpose

We have been producing taphole drilling tools for blast furnaces for over 40 years. Longer and longer tapholes, smaller drill diameters, harder taphole masses and shorter tapping times on modern blast furnaces required a constant development and improvement of our tools. Thanks to our excellent price-performance ratio and close cooperation with our customers, we have become one of the leading international manufacturers of taphole drilling tools. One of the most important features of our drilling tools is to open tapholes cleanly, efficiently and economically. We are also constantly developing the operability of the tools to ensure safe and quick tool changes during operation. The larger center cooling hole ensures a strong flow of air / nitrogen or water mist. The symetrical cutting edges extending down the entire side of the bit also allow very good cleaning results of clay debris and slag or iron inclusions when pulling the rod out under rotation.
