Rivet busters are Pneumatic air hammer chisels which use a heavy duty percussion action to punch or cut construction materialsįor removing old rivets this is typically done in 2 stages. Reducing the use of dangerous Rivet Busters ( also known as Rivet bursters & Pneumatic Hammers) Impact Reamers do not have a torque kick-back which is a hazard with some power tools and air tools Products such as Impact Reamers can be used in Impact Wrenches providing a safety improvement. This gives effective results in these tight working areas Holemaker Technology have developed innovative drilling tools to speed up rivet removal and rework/replace connection holes for new bolts.ĭue to the unique challenges of bridgeworks, the Versadrive range is becoming widely used as the patented hex shank system allows effective use in cordless, rotary, and impact power tools. This is complicated by the original fabrication methods of hot rivets and multiple layers of plated steelworks Over time, steel bridges become corroded and need strengthening and repairs. This range is developed to help fabricators and site workers get the best results in the time available We recognise there are a range of unique challenges for bridge works including tight access, corroded materials, and time pressure from possessions. Bridge strengthening and steelwork repair is an essential part of keeping transport flowing and keeping passengers safe
