Standard drills

There are two types of power drill used in the bodyshop:the majority are usually electrically driven and require a 13A electrical power point (Figure 3.50),while the others are air powered and require a compressor and air points (Figure 3.51).
The most popular sizes in common use are the in (6.3mm) pistol drill,and the in and in (9.5mm and 12.6mm) heavy-duty machines. Drills are used mostly for drilling out spot welds along damaged panels which need removing,and also for drilling out broken rivets and bolts. As well as the standard size drills there is a special drill called an angle drill,which is extremely useful in bodywork as it can be used in confined spaces and enables many otherwise impossible drilling tasks to be carried out (Figure 3.52).
