If you find any of these, then it\u2019s time to replace the blade. A blade with chipped or missing teeth is hazardous as it\u2019s more likely to cause kickback and further teeth breaking off.<\/li>\n<li>If you\u2019re not sure how sharp the teeth ought to be, an easy way to check is by comparing your blade with a new one. Feel the sharpness of the teeth with the back of your fingernail, and then compare the sharp blade with the one you\u2019re inspecting. If there is a significant difference, that\u2019s a good indicator your old blade will need sharpening\/replacing.<\/li>\n<\/ul>\n<p>Another thing to consider is whether your blade is dull or merely dirty and gummed up from wood resin buildup. This can happen if you cut a lot of softwoods like pine which has a tendency to gum up your blade. If this is the case you can often improve the performance by giving the <a href=\"https:\/\/www.woodmagazine.com\/woodworking-tips\/techniques\/sawing-solutions\/clean-cutters1\" target=\"_blank\" rel=\"noopener\">blade a thorough cleaning<\/a>.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"How_Long_Does_a_Circular_Saw_Blade_Last\"><\/span><strong>How Long Does a Circular Saw Blade Last? <\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><a href=\"https:\/\/homeimprovementscout.com\/can-i-use-a-smaller-blade-on-my-circular-saw\/\">Circular saw blades<\/a> can last anywhere from a few months to a decade or more, it really depends on the type of blade, what you cut with them, and how often you use the blade.<\/p>\n<p>There are two common blade types used for cutting wood: carbide-tipped and stainless steel.<\/p>\n<ul>\n<li style=\"padding-bottom: 16px;\"><strong>Carbide tipped<\/strong> <strong>blades<\/strong> are the most common type sold today, and feature carbide-tipped teeth attached to a hardened steel blade. They last significantly longer than stainless steel blades, often lasting for several years before needing replacement.<\/li>\n<li><strong>Stainless steel blades<\/strong> were the most common type before the invention of carbide-tipped blades. They last significantly less time than carbide-tipped blades but are easier to sharpen on your own. These blades will only stay sharp for about a tenth as long as carbide-tipped blades.<\/li>\n<\/ul>\n<figure id=\"attachment_1539\" aria-describedby=\"caption-attachment-1539\" style=\"width: 790px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-1539 size-full\" src=\"https:\/\/i0.wp.com\/homeimprovementscout.com\/wp-content\/uploads\/2021\/12\/carbide-tipped-saw-blade.jpg?resize=800%2C553&#038;ssl=1\" alt=\"carbide tipped circular saw blade\" width=\"800\" height=\"553\" srcset=\"https:\/\/i0.wp.com\/homeimprovementscout.com\/wp-content\/uploads\/2021\/12\/carbide-tipped-saw-blade.jpg?w=800&amp;ssl=1 800w, https:\/\/i0.wp.com\/homeimprovementscout.com\/wp-content\/uploads\/2021\/12\/carbide-tipped-saw-blade.jpg?resize=300%2C207&amp;ssl=1 300w, https:\/\/i0.wp.com\/homeimprovementscout.com\/wp-content\/uploads\/2021\/12\/carbide-tipped-saw-blade.jpg?resize=768%2C531&amp;ssl=1 768w\" sizes=\"(max-width: 800px) 100vw, 800px\" data-recalc-dims=\"1\" \/><figcaption id=\"caption-attachment-1539\" class=\"wp-caption-text\">Carbide-tipped saw blades last significantly longer than their stainless steel counterparts.<\/figcaption><\/figure>\n<p>Another consideration is what materials you use your blades with. Hardwoods have a tendency to wear out blades faster than softwoods, and if you cut through material with nails or screws embedded you\u2019re bound to decrease the lifespan significantly.<\/p>\n<p>Of course, how often you use a blade will have a major impact on its lifespan. If you\u2019re a contractor and use your saw on a daily basis, you\u2019re going to need to replace it more often than a DIYer who picks up their saw every other weekend.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Should_you_Sharpen_Clean_or_Replace_a_Blade\"><\/span><strong>Should you Sharpen, Clean, or Replace a Blade?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>When you\u2019ve got a dull blade, you basically have three options: clean it in hopes of getting it working properly, replace it with a new one, or sharpen it. Let\u2019s briefly take a look at each of these options.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Cleaning_the_Blade\"><\/span><strong>Cleaning the Blade<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><a href=\"https:\/\/homeimprovementscout.com\/how-to-clean-a-saw-blade\/\">Cleaning a blade<\/a> can potentially restore it from poor performance to working like new. You won\u2019t really know though until you try though.<\/p>\n<p>Cleaning a saw blade is fairly straightforward; all you need is a bucket, an old brush, some blade cleaning solution, and little elbow grease. It\u2019s also significantly cheaper to clean a blade than buy a new one.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Replacing_the_Blade\"><\/span><strong>Replacing the Blade<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>If the blade is beyond the point where cleaning it is enough, then it\u2019s time to <a href=\"https:\/\/homeimprovementscout.com\/how-to-change-a-circular-saw-blade\/\">replace it.<\/a> A quality carbide-tipped blade can be had for $20 to $30, so replacing an old blade is cheap enough that your wallet won\u2019t notice the hit much.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Sharpening_the_Blade\"><\/span><strong>Sharpening the Blade<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>There\u2019s also the option of sharpening a blade once it\u2019s too dull to use.<\/p>\n<p>Stainless steel blades are fairly easy to sharpen on your own with a hand file, so if you\u2019re partial to repairing your own gear this is a good option. Carbide-tipped blades are more difficult to sharpen, so unless you have a diamond wheel you\u2019ll probably want to get your blade professionally sharpened.<\/p>\n<p>Blade sharpening typically costs between 25\u00a2 and 50\u00a2 a tooth. This works out to $10 to $20 per blade. So, for cheap blades, it\u2019s generally cheaper to just replace them, but more expensive specialty blades can be worthwhile to sharpen.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>If you\u2019re noticing your circular saw blade isn\u2019t cutting as smoothly as it once did, then you\u2019re probably wondering when it\u2019s time to replace it with a new one.<\/p>\n","protected":false},"author":1,"featured_media":1536,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"om_disable_all_campaigns":false,"_monsterinsights_skip_tracking":false,"_monsterinsights_sitenote_active":false,"_monsterinsights_sitenote_note":"","_monsterinsights_sitenote_category":0,"_uf_show_specific_survey":0,"_uf_disable_surveys":false,"footnotes":""},"categories":[9,7],"tags":[],"aioseo_notices":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v21.7 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>When to Replace a Circular Saw Blade?\u00a0 - Home Improvement Scout<\/title>\n<meta name=\"description\" content=\"If you\u2019re noticing your circular saw blade isn\u2019t cutting as smoothly as it once did, then you\u2019re probably wondering when it\u2019s time to replace it with a new one.
