A table saw is a workhorse tool. You can use it to rip through a truckload of wood in no time. However, with all that power comes great risk. Table saws can cause serious bodily injuries if you use them for the wrong purpose or in the wrong way.
The most common danger with a table saw is kickback. A kickback happens when your material catches on the blade and is launched into the air. If you want to stay safe and avoid injury, here are seven different cuts you should never do with a table saw.
7 Cuts Not To Use a Table Saw For
1. Make curved cuts
A high quality table saw is meant to make straight cuts at high-speed. It is not intended for curved cuts. If you try to feed the material at an angle, the spinning blade will grab the piece and send it flying. This is known as kickback. The best way to avoid kickback is to make straight cuts.
2. Cut plastic
The blade on a table saw moves fast and generates heat, which is not ideal for cutting plastic. Slap cutting, putting the blade in backwards, is a technique some people try with a table saw. It’s not a safe method and it will melt the plastic instead of cutting it.
3. Make backwards cuts
Sometimes, you’ll want to make a climbing cut with your table saw. This is also known as feeding the piece in backward. Woodworkers will sometimes make climbing cuts to mark a new piece or because it is the easiest way to position the piece.
While you can make climbing cuts using other kinds of saws, you should never try it on a table saw. The blade will bite and pull the wood and then push it away causing it to kickback.
4. Cut ferrous metals, like cast iron or steel
If you need to cut metal, there are a lot of better tools than a table saw. Ferrous metals will cast sparks when they hit the blade. The cast sparks can cause burns and ignite any sawdust or wood in your work area.
The other danger is flying pieces of metal. If a piece of metal kicks back, it could cause serious injuries. If you use a metal cutting blade and go very slow, you can cut non-ferrous metals such as aluminum, copper, nickel, silver, and brass.
5. Make angled cuts without bevel capability
An beveled cut is not a good idea to try on a table saw. The chances that the material will kickback are increased when you try to make angled cuts. If you must make an angled cut, use a miter saw or miter gauge to guide the material safely.
6. Make freehand tapered cuts
Sometimes, you’ll need to make a long angled cut. Maybe you need to make a shim to fit in an angled space. Even a slightly angled cut is not recommended on a table saw. The blade will catch on the material and cause a kickback. If you want to make a tapered cut, you will need a taper jig. You can use it to safely guide the wood at the angle you need.
7. Cut PVC pipe
A table saw is not the right tool to cut through plastic piping. PVC pipe will melt or rip on the saw blade. You won’t be able to make clean cuts through PVC pipe with a table saw, plus the material will want to catch and spin on the blade causing dangerous kickbacks.
