- Improper saw maintenance
- Forcing the blade
- Material support and fence contact
- Foreign objects
Let’s look at each of these causes in more detail and discuss how you can fix them.
No 01: Blade Binding
Kickback occurs when the saw blade binds in the material, often due to the kerf closing in on the blade. This can happen when the saw blade gets pinched by the material, causing it to stop suddenly and reverse.
To prevent blade binding and potential kickback, choosing the right blade for the job is essential. Ensure you’re using a sharp blade appropriate for the type of wood you’re cutting.
Different types of wood require different blades, so be sure to select one that matches the hardness and density of the wood you’re working with. Blades designed for sliding miter saws often have features specifically to reduce binding.
No 02: Wood Irregularities
Wood with irregularities can lead to kickback on your miter saw. When the blade encounters a knot or warped section, it can cause the wood to shift or bind, resulting in a dangerous situation.
To prevent this, take the time to carefully examine your material before cutting. Look for any knots, cracks, or areas of warping. If you spot any, approach them with caution. Make sure the blade is well clear of these areas to avoid binding.
No 03: Wet or Pitchy Wood
Using wet or pitchy wood increases your risk of kickback due to the blade binding and not cutting smoothly. When wood is wet or contains pitch, it becomes sticky and can cause the blade to get stuck during the cutting process. This can result in the wood being thrown back towards you, causing injury or damage.
To avoid kickback when working with wet or pitchy wood, it’s important to take certain precautions.
- Ensure that your miter saw blade is sharp and in good condition.
- Consider using a blade specifically designed for wet or resinous materials with special coatings and tooth designs to prevent buildup.
