The NEW Master 35® Impact Wrench is now powered by a more powerful Engine which complies with EUR5 and EPA3 low emission Standards.

Because of its increased power and high engineering specification it will remove/fit most Chairscrews and Fishplate Nuts in under three seconds and using one of our Safety Quick Release Auger Attachment drill holes in Wooden Sleepers.

It is easily carried by one person, is operator friendly, has good balance, easy to repair and because it is so fast, reduces the potential harm of vibration exposure especially when fitted to our Tool Carrier.
