There are significant environmental advantages to be gained by using this cordless technology in place of drill and fix since there is no vibration to the operator, minimal exposure to dust and no electrical energy use. Hilti Direct fastening also provides a tested reliable fixing method with a range of small steel fasteners which can also reduce the amount of raw material in the fixing ap- plication. page 10
