Cold chisels are used by the Engineering and building trades to remove waste metal when a very smooth finish is not required, cutting and chipping brickwork or stone and when the work cannot be done easily with other tools, such as a hacksaw, file, bench shears or power tools. The angle of the cutting edge should be 60 to 70 degrees, inclusive, but it is dependant on the material to be cut. When cutting metal, the softer the material is, the more acute the cutting angle should be.
Taper punches used for aligning holes in jigs and fixtures etc. With a hexagonal body for extra grip.
