Air hammers from SIP are a valuable addition to the armoury of tools in the professional automotive body shop. Air hammers are powerful air tools with chisel attachments perfect for all rust removal applications, and for cutting out damaged metal sheeting in accident repair jobs. Five Chisel Extras The design of SIP air hammers incorporates a spring mechanism allowing the chisels to be changed over quickly and easily while working. A fine finger tip control adjusts the chisel strike rate as required. A basic set of five chisels is supplied with the air hammer, usually including a spot weld cutter, a panel cutter, a taper punch, a flat chisel, and a sheet metal trimmer. A needle scaler is available as an optional accessory.
