Everything You Need To Know About Saw Blades
Saw blades come in a wide range of sizes to accommodate different gauges of metal, the idea being that you change them regularly rather than sticking to just one. A saw cut is initiated from the edge of the metal or a carefully pre-drilled hole, although as you work your saw blade requirements will alter. For example, sawing in a straight line requires a thicker blade than a curve, which it is better to use a finer blade for – so in time quickly changing blades will become second nature. Use our jeweller’s saw blades sizing chart to help get you started.
Understanding What Size Jeweller’s Saw Blade To Use
The grade of a saw blade is determined by the amount of teeth it has per cm. So, a blade with more teeth will be finer as they have to be smaller to fit into the space along the shaft and vice versa. Fine blades are better suited to thinner metal, and coarser ones are recommended for thicker metal as you can see from the chart below. As a general rule, you are aiming to encompass two teeth of the blade within the thickness of your metal.

Saw blades are graded from 4 (coarsest) to 8/0 (finest). This gives you 11 different sizes to choose from, which might seem a little daunting at first. However, you can purchase mixed selection packs which is a good place to start, or alternatively, choosing a size which is somewhere in the middle such as a Grade 2/0 or Grade 0 (1/0) will stand you in good stead. Most are sold in bundles of 12 which initially seems a lot, but most beginners get through a lot when learning to saw so it’s best to stock up.
What Are The Best Jeweller’s Saw Blades For Gold, Silver & Platinum?
If you like working with a particular alloy, you might just want to know what size jeweller’s saw to use for it. So as a rule of thumb for deciding which jeweller’s saw blade sizes to go for, this is what we’d recommend:
- Gold. If you tend to use gold for your jewellery pieces, choose a 3/0 blade.
- Silver. For cutting silver, opt for a blade with a grade of 2/0.
- Platinum. To ensure your platinum work is finished to the highest standard, use a 3/0 blade.
