Builders’ and cold chisels are available in a variety of different sizes.
Sometimes, the measurement given may simply refer to the cutting edge; other times it may refer to the length of the tool.
For certain chisels (such as plugging chisels), the tip may be included as well.
Cold chisel sizes
Cold chisel cutting edges are available in a number of different sizes. Listed below are just a few. Please note that as size varies by manufacturer, those listed are only approximate (as are the imperial measurements):
16mm (5/8 inch).

Concrete (point) chisel sizes
For concrete point chisels, it can be difficult to give a measurement for the size of the tip, due to the fact that it narrows to a point. However, the size of the tip can vary, with sizes including approximately 5mm (13/64 inch) and 20mm (51/64 inch).
(fluted) plugging chisel sizes
Plugging chisels can be found with cutting edges of various sizes including 16mm (5/8 inch), 25mm (1 inch) and 32mm (1 & 1/4 inches).

Please note, the user should use bits which are the same size as the scutch comb holder.

Why would you use a smaller chisel?
Smaller chisels may be desirable when doing work which is more delicate in nature or when working in a smaller environment, such as removing holes from pattress boxes for cables.
In addition, a longer chisel may be useful when trying to get into hard to reach areas or when removing floorboards.
