How dangerous are circular saws?
Circular saws have faster blades than table saws, with an outer edge spinning at about 120 mph, and they can cause some serious damage if used incorrectly or recklessly. A study in Australia’s Hazard Magazine found that of all reported saw injuries, circular saws make up the largest group at 30 percent.
Why does my circular saw keep kicking back?
Overheating a saw blade can cause it to warp and result in a kickback. Buildup of sap on the blades, insufficient set, dullness and unguided cuts, can all cause an overheated blade and kickback. Never set a blade deeper than is required to cut the work piece 1/8 in. to 1/4 in.
Why do circular saws kick back?
Kickback happens when the saw blade binds or stalls suddenly in the wood and the saw gets driven back toward you. So the key to preventing this is to make sure your blade doesn’t bind in the wood. If you feel the saw beginning to bind, release the trigger so the blade will stop.
Can a 7 1 4 circular saw cut a 4×4?
Circular Saw A circular saw is one of the best means of cutting a 4×4 post. Like miter saws that measure less than 12 inches, a circular saw’s 6.5-inch or 7.25-inch blade will not cut cleanly through a 4×4. The maximum depth of most circular saws is just 2.5 inches. This means you’ll need to make two cuts.
Why does my circular saw burn the wood?
A Dull or Dirty Saw Blade Might Be the Culprit Pushing the stock through the saw too slowly is a common cause of saw blade burn. Sometimes a blade that feels dull might only be dirty. If wood pitch resins build up behind the teeth of the blade, the cutting speed will slow down, increasing the chances for burns.
How can you tell if a circular saw is bad?
Look for worn-down, chipped, broken and missing teeth or chipped carbide tips that indicate it’s time to replace a circular saw blade. Check the wear line of carbide edges using a bright light and magnifying glass to determine if it’s beginning to dull.
