Mini Circular Saw Blades
In addition to wood, metal, plastic, and concrete, circular saws may be used to cut a wide variety of other materials. The quality of your cuts will depend on the quality of the blade you use in your circular saw, so be sure you get the right one for the task. There are various varieties of circular saw blade, all tailored for specialised tasks. Here you will find all the information you need about the many kinds of circular saw blades, whether you are seeking for a particular blade recommendation for a job or a general review of the options available to you. Check out this video for a primer on some of the topics we’ll cover.
Mini Circular Saw Blades Types
Ripping blades are optimised for use in cutting with the wood’s natural grain. They have fewer teeth than humans do, often between 14 and 24, and a bigger gullet. Use these when you need a quick, rough cut.
Knife with a Serrated Crosscutting Edge
In order to make cuts perpendicular to the grain of a piece of wood, crosscutting blades are used. Their gullet is smaller and they have more teeth than a ripping blade. They take longer to cut but leave a better surface afterward.
Cutters designed for plywood often contain 40 or more teeth since the material chips and splinters so readily. Using these blades on fine material will reduce the likelihood of splintering while you work.
They fall in between ripping and crosscutting blades in terms of effectiveness. They’re great if you just need one blade for several tasks, but if you require one for a particular purpose, it’s best to invest in a dedicated blade.
With a finishing blade, you may make clean, accurate cuts in the areas of the wood that will be on display after the task is done. This is because they are equipped with more teeth and designed to make clean, careful cuts without marring the wood.
The Dado Sword
There are dedicated blades for tasks like making dados, rabbets, and grooves.
Miniature Knife with a Thin Kerf
The width of the slit made by the blade is known as the kerf, and a thin kerf blade is one that leaves a very small slit in the wood. For slicing through 2x4s and other pieces of dimensional timber, these blades are your best bet. Cuts will not be straight when using a narrow kerf blade on harder wood because of the blade’s tendency to bend.
Wood that has been chemically altered
For cutting through treated wood, a blade with a wider kerf is recommended. You’ll have an easier time making perfectly straight cuts.
Blades designed for work with wood may often be adapted for use with plastic. The optimal number of teeth is between 40 and 60, although the bigger the number, the better. Soft metals may also be cut with this kind of blade.
Knives for use in stonemasonry
Cutting masonry requires a special kind of blade that differs greatly from woodcutting blades, most notably in the absence of teeth. Instead of slicing through the brickwork like a pair of woodcutting blades, they are composed of fiberglass-reinforced silicon carbide abrasive and wear it away. This is the only blade that will work for cutting any form of brickwork.
Shearing and Cutting Metal
Metal may also be sliced using specialised blades. Most metals, including ferrous and non-ferrous, may be cut with toothless blades that include expansion holes.
The Different Features Of A Saw Blade
- Number of teeth-One of the most obvious features of any circular saw blade that will be immediately recognizable even to someone who has never used a circular saw in their life is the number of teeth.In general, the fewer the teeth a blade has, the quicker it cuts but also the rougher it cuts. If you want cleaner, more precise cuts, you should choose a blade with more teeth.
- Gullet- The gullet is the space in between each tooth. Deeper gullets are better at removing larger chips of wood while shallower gullets are more effective at removing finer sawdust from the cut.
- Expansion slot-Some blades include expansion slots. These are designed to let the metal of the blade expand slightly as it heats up, allowing you to continue cutting efficiently.
- Size-Regular circular saw blades are 7 ¼” – but other sizes exist. For example, mini circular saws can have blades of only 4 ½”. This means you need to make sure you choose the right size for your tool.
