EVOLUTION 7" 48-Tooth Carbide-Tipped Stainless Steel Cutting Blade, 7-inch .070" Kerf, Low-RPM (20mm Arbor)

EVOLUTION's 7-inch 48-tooth carbide-tipped blade is a stainless-steel cutting blade engineered to slice metal with minimal heat, low burrs and a precise 0.07-inch kerf.

This circular saw blade is purpose-built for metalworkers, fabricators and tradespeople who need clean, controlled cuts in stainless steel and other ferrous metals. Using EVOLUTION's dry-cut philosophy, the blade’s carbide teeth and tooth geometry reduce friction and heat build-up so you get smoother edges without coolant. It is optimized for low-RPM saws (up to 3900 RPM) and fits a standard 20 mm arbor, making it a practical upgrade for Evolution saws or other compatible low-speed metal-cutting saws.

How does this blade reduce heat and burrs when cutting stainless steel?

The blade’s carbide tips and tooth pattern are arranged to slice metals efficiently while shedding swarf, which lowers surface temperature during cutting. Less heat means fewer heat-affected zones, and the tooth count helps deliver finer finishes with smaller burr formation compared with coarse-tooth blades.

• 48 carbide-tipped teeth for a finer cutting action
• Dry-cut design minimizes friction and thermal transfer
• .070-inch kerf reduces material waste and load on the saw

Will this blade work with my saw — what are the fit and RPM limits?

The blade has a 20 mm arbor and is designed for use on Evolution-brand low-RPM metal saws as well as other machines that accept a 20 mm arbor. It’s rated up to 3900 RPM, so it’s intended for slower, torque-focused metal cutting rather than high-speed wood cutting applications.

• 7-inch diameter fits common compact metal saws
• 20 mm center bore for compatibility with Evolution and similar saws
• Maximum safe speed: 3900 RPM — suitable for low-RPM metal cutting

What cutting results and materials can I expect from this blade?

Primarily tuned for stainless steel and other ferrous metals, this blade delivers accurate, relatively burr-free cuts and a narrow kerf that preserves material. It will also cut thin sections of mild steel and other alloys, but you should avoid higher-speed wood or masonry tasks for which it was not designed.

• Best for stainless steel and ferrous alloys
• Produces cleaner edge finishes compared with coarse tooth metal blades
• Not intended for high-RPM wood or masonry cutting

Who is this for? If you’re a metal fabricator, sheet-metal worker, maintenance technician or serious DIYer who uses low-RPM metal-cutting saws and needs repeatable, cleaner cuts in stainless steel, this EVOLUTION 7" 48-tooth carbide-tipped blade is a practical choice. It suits projects that demand reduced burr cleanup and lower thermal impact, and it fits saws with a 20 mm arbor rated up to 3900 RPM. Pair it with the correct blade guard and secure clamping for accurate, safe cuts.
