The newT-WiZ drill string, with its combinationof T-WiZ Speedrods and T-WiZ shankadapters, offers up to 30 per cent longerservice life resulting in fewer rod changesand more productivity per shift.T-WiZ claims to be the toughest systemon the market thanks to its greater threadstability and is robust enough to preventproduct breakage in the blast hole. Thisputs an end to time-consuming rod andshank changes and helps to keep stock low.Regardless of the assignment – whetherit be underground, in surface mines or onconstruction sites – T-WiZ makes a substantialdifference in tough formations andfractured rock.The increased capacity provided byT-WiZ – in other words, more holes pershift – also paves the way for faster blastingand a more rapid advance.There are three dimensions to choosefrom – T38-WiZ, T45-WiZ and T51-WiZSpeedrods and shank adapters designed forextension or drifting drill strings. In addition,these systems are all perfectly matchedto the comprehensive range of Secoroctophammer bits.
