Description
Centre Punches are ground to a strong point with an included angle of 90 degrees (in a similar manner to a Scriber).
Features and Uses
To stop a drill bit skidding about a metal surface, these are used to make a small indentation to locate the drill centre.
Note: Hold the punch to an angle to position on centre then raise to the vertical and strike it sharply with a hammer - but only once - striking several times may cause the punch to bounce around.
DT Online Buyers' Guide
- All punches shown have a good knurled grip.
- Those with a square head are less likely to roll off the bench.
