I was sent 3 different blades for 2 different circular saw sizes that I don’t have, so I had to go buy some new toys just to be able to review them. I’m a huge fan of Diablo blades, all day every day, so I was excited to break these out and test them.

The 3 blades I’m using today are the 6 1/2-inch 24-tooth framing (wood) blade, the 6 1/2-inch 32-tooth metal/wood blade, and the 5 1/2-inch 18-tooth framing (wood) blade. I have several 7 1/4” circular saws but no 6 1/2” or 5 1/2” saws, so I went to the Depot and bought one of each. More tools? Hell ya!


6 1/2-inch 24-tooth Framing Blade

The Claim:

  • Compatible with any 6-1/2″ corded or cordless circular saw

  • Cut hardwood, 2x lumber, pressure treated, osb & laminated beams

  • 5x life, 2x durablility, 65% more cuts per charge

This Diablo 6-1/2 in. Saw Blade produces accurate, smooth cuts on framing materials without bogging down your power tool. Even underpowered circular saws can spin this 24-tooth saw blade with precision thanks to a super-thin kerf that minimizes material removal and produces fast, clean swaths. A Perma-SHIELD nonstick coating reduces drag while stabilizer vents absorb noise and vibration to keep the blade straight on rips and cuts.

  • TiCo high-density titanium carbide composition increases performance and maximizes cutting life

  • Perma-SHIELD nonstick coating reduces drag and shields the blade against heat and friction

  • Laser-cut stabilizer vents absorb noise and vibration, keeping the blade straight and true for superior quality cuts

  • Designed to fit 5/8 in. arbors for accurate blade rotation

  • Ultra-slim kerf provides fast, clean cuts with minimal material removal, ideal for underpowered saws on a job site

This is a great blade for cutting lumber. I love that Diablo adds little vent cut-outs on their blades that reduce heat and help with vibration. The saw cuts extremely well, and I have yet to reach the limit of it’s cutting ability. It’s carbide, and it’s a wood blade so I imagine these teeth will stay sharp for a really long time.


6 1/2-inch 32-tooth Metal and Wood Blade

The claim:

  • Optimized for all corded and cordless saws

  • Industry’s first multi-purpose blade for cutting wood and metal

  • TiCo Carbide for durability in wood/ metal cutting applications

From Home

Diablo’s new 6-1/2 in. Wood and Metal saw blade is the industry’s first multi-purpose saw blade for cutting clean wood and wood with nails, up to 2 material thickness; and metal ranging from 3/32-1/4 wall thickness and 1/4-1 in. Dia. The versatility of these new blades provides the ability to use the same blade to cut wood and metal so now users can focus on completing the job more efficiently rather than wasting time with changing tools and saw blades. The Diablo made TiCo carbide tips, which are specially designed for this blade, coupled with the blades Chamber-Alternate Tooth Design (C-ATB) tooth design provides impact resistance for cutting wood with nails as well as the durability for creating clean, burr free cuts in metal. Optimized for corded and cordless saws, this new blade cuts 2X lumber, wood with nails, angle iron, channel, flat bar, steel studs and threaded rod.

  • Specially formulated Diablo TiCo carbide withstands impact, reduces wear and lasts longer in wood and metal cutting applications

  • Chamfer-alternate top bevel (C-ATB) tooth design cleanly shears through wood while providing the durability needed for clean, burr-free cuts in metal

  • Cuts up to 2 material thickness in clean wood and wood with nail cutting applications

  • Cuts 3/32-1/4 wall thickness in steel studs, channel, angle iron, pipe, tubing, plate and bar stock

  • Cuts 1/4-1 in. Dia threaded rod

  • Wood with nails as well as the durability for creating clean, burr free cuts in metal

I’ve never been able to cut conduit or uni-strut with a circular saw before, so it’s pretty outstanding that they now make metal-cutting circular-saw blades. I will warn you, however, that the speed of this saw can be dangerous when cutting metal. Any spinning saw blade is going to kick out sharp, hot material – so when cutting metal it is very easy to get hot, sharp metal shards embedded in your eyeball or skin, as has happened to people I work around on jobs. Make sure you protect yourself and wear proper PPE, especially when cutting metal. No joke, I will only use this blade with a face-shield, long sleeves, and gloves now.


5 1/2-inch 18-tooth Framing Blade

The Claim:

  • Use with cordless arbor saws for smooth cuts on framing materials

  • Includes 3 bushings to fit 1/2 in., 5/8 in., 10 and 20 mm saws

This 20 mm arbor saw blade includes 3 additional bushings that allow your blade to also fit on 1/2 in., 5/8 in. or 10 mm arbor saws. These blades feature Diablo made TiCo Hi-Density Carbide engineered exclusively to maximize life, performance and durability in wood cutting applications. The thin kerf body minimizes material removal and requires less cutting power, delivering fast, clean rips and cuts.

  • Diablo made TiCo hi-density carbide specifically designed for framing applications to provide maximum performance and life

  • Advanced laser cut thin kerf blade gives extremely fast, effortless cuts in cordless saws

  • Laser-cut stabilizer vents trap noise and vibration keeping the blade cool and reducing blade warp

  • Non-stick Perma-Shield coating reduces gumming, rusting and corrosion

  • Optimized for 1/2 in., 5/8 in., 10 mm and 20 mm cordless saws

  • Compatible with Makita (5/8 in. arbor), Black and Decker (1/2 in. arbor), Ryobi (10 mm arbor), porter cable (10 mm arbor) and Craftsman (10 mm arbor)

  • Ideal for hardwoods, softwoods, 2X lumber, pressure-treated lumber, OSB, plywood and laminated beams

If you’ve got a min-circular saw that can fit a 5 1/2-inch blade, this is a perfect little wood-saw blade. I now have every size circular saw you can buy, and with this blade I’m able to use my M12 Milwaukee cordless saw – which is much lower power than most of my other size, due to the small batteries. But it also is one of the lightest circular saws I own, which when light-weight and compact is what’s needed, this is now my go-to blade and saw combo.



Diablo makes, hands-down, the best blades out there. They were bought out by a company named Freud who makes some of the best industrial (large) saw blades on the market, and having merged their technologies, they now make light and heavy construction products. I only use Diablo. Yes, they’re a little more expensive than other brands, but that expense is the difference you get in quality and innovation. I’m ok spending more to get the best with my blades. 5 out of 5 stars for all 3 of these.
