The Kreg 7-1/4-in. SureCut Finishing 40-Tooth Saw Blade is a general-purpose finishing blade sized for the most common circular saw on any jobsite. Model number KSB725FIN40. It's built as the everyday upgrade blade — one step finer than a framing blade, aimed at plywood, hardwood, and trim work where a stock blade leaves a rougher edge than you want.

40 carbide-tipped teeth on a 7-1/4 in. plate is a well-balanced tooth count. It's fine enough to noticeably clean up cuts in plywood and hardwood compared to a 24-tooth framing blade, but it's not so dense that feed rate drags to a crawl the way an 80-tooth blade would on the same saw. For a carpenter who needs one blade to handle both general building and reasonably clean finish cuts, this tooth count is the practical middle ground.

The PTFE anti-stick coating and anti-vibration relief cuts are the same engineering Kreg uses across the SureCut line, and they matter here because this is likely the blade that stays mounted the longest — a 7-1/4 in. circular saw blade sees more total cuts over its life than a specialty blade that only comes out for finish work. Keeping the plate clean and stable over that higher cut volume is what extends the useful life of the blade.

This blade uses a 5/8 in. arbor with a 1.5 mm kerf, which is the standard fit for the vast majority of 7-1/4 in. circular saws, corded and cordless, across every major brand.

Who should buy this: general contractors, remodelers, and DIYers who want a genuine step up from a stock or big-box blade for everyday plywood, trim, and hardwood cuts, without stepping all the way up to a dedicated ultra-fine finishing blade. If you're cutting mostly framing lumber and don't need a clean edge, the 24-tooth general purpose blade in this same line is the better fit and will hold up longer under rough use.

The one blade that covers most of the job

40 teeth is the number Kreg landed on for a reason — it's the blade that handles plywood and trim without giving up all-day practicality.

• Who it's for: General contractors and DIYers who want one solid upgrade blade for their everyday 7-1/4 in. circular saw.
• Why it stands out: Balanced tooth count, PTFE anti-stick coating, and anti-vibration relief cuts in the size of blade most people already own a saw for.
• Worth knowing: If your work is mostly rough framing, the 24-tooth general purpose blade in this same line will hold up better under that specific use.

• What's the difference between this and the 24-tooth general purpose blade? This 40-tooth blade leaves a smoother edge for plywood, hardwood, and trim; the 24-tooth blade is built for faster cutting in framing lumber.
• What saws does this fit? Standard 7-1/4 in. circular saws, corded or cordless, with a 5/8 in. arbor.
• Can this be resharpened? Carbide-tipped blades like this one can typically be professionally resharpened several times before replacement is needed.
