A piercing saw, often called a jeweller’s saw, is essentially a smaller version of a coping saw.
Just like a coping saw, a piercing saw has a U-shaped frame and a removable blade.
The only difference is that a piercing saw tends to be smaller than a coping saw, and the blades available to fit it are usually thinner, and have more teeth per inch.
As a result, a piercing saw is capable of producing finer cuts, tighter curves and a neater finish.
A piercing saw can be used in much the same way as a coping or fret saw, but greater care should be taken so as not to damage the delicate blade.
There are blades available which can cut through wood, plastic and metal.
Some piercing saws have adjustable frames to accommodate different length blades
Why is it also called a jeweller’s saw?
A Piercing saw is often used by jewellers for very fine metal-working applications.
