- Use a Splitter.
- Consider a Crosscut Sled.
- Always Use a Push Sitck.
- Don’t Let Your Guard Down.
What causes kickback?
Reasons for kickback
A common reason kickback occurs is tension in a board. As the wood is cut, the tension keeps the kerf from fully opening. This causes the end of the cut to pinch together trapping the blade (as in the sketch below) and the wood comes at you with incredible speed.
Does a riving knife prevent kickback?
A riving knife is a great feature and will prevent most kickbacks, but you still need to use proper technique and not stand directly behind the blade because it can still happen.

How do anti kickback pawls work?
A pawl is a type of latch that prevents movement. Anti-kickback pawls reduce kickback as you feed a board through a saw. Anti-kickback pawls look like two tiny saws joined together, each having pointed teeth. Those teeth hang behind the saw so that when you push wood through, they will run across the top of the wood.
What is anti kickback chain?
May 27, 2011. 3 Comments. Some chainsaw chains are designed to minimize the reactive force known as kickback. These chains are found on a wide range of chainsaws made for homeowners, arborists, and loggers and are required to be sold on every new saw with an engine displacement of less than 66 cubic centimeters.
What causes kickback on a circular saw?
Kickback is a fact of life for anybody who uses a circular saw often. It is caused by the timber that is being cut, bending in some way, so that it jams on the back of the blade, making the saw buck or stall.
How do you keep a circular saw from binding?
Avoid circular saw blade binding
You can hold one end, but the other must be free to drop or the blade will bind. The trick is to allow the cutoff end to drop slightly, but not so much that it completely snaps off before the cut is complete. One method is to support the board with strips of wood as shown here.
What direction should a circular saw blade turn?
Circular saws rotate by default in a counter-clockwise direction. The teeth of a circular blade are designed to cut on the upstroke in the forward direction. This pushes the material forward and towards the blade so that it helps maintain control of the saw and the workpiece.
What is the safest saw?
A reciprocating saw (e.g. Sawzall®) is quite finger-safe if you keep both hands on it – but then, so is a common portable circular saw, if you keep both hands on it. If you are not using both hands on the saw, you are doing it wrong.
What is the difference between a splitter and a riving knife?
The difference between the two is that a riving knife moves up and down with the blade keeping the same distance from the blade, while a splitter mounted guard remains at a fixed height since it is mounted to the table trunnion so it can bevel with the blade.
How thick should a riving knife be?
A properly sized riving knife is thinner than the teeth, but thicker than the body, of the blade to which it’s paired. If the 0.94″ is the widest riving knife that Dewalt makes for that saw, then it should be OK to use with a 1/8″ blade but I would double check the body thickness with a micrometer.
Do I need a riving knife?
Rip cuts are especially prone to kickbacks, and it is here that the riving knife is most important. Even though a riving knife is effective in reducing the possibility of a kickback, it cannot prevent it entirely, which is why it is always advisable to follow the basic rules of use for a table saw.
