3PACK 3-Inch(75mm) 36T TCT Circular Saw Blade with 3/8-Inch(9.5mm) Arbor, Fast Clean Wood Plastic Cutting Cut-Off Wheel Compatible with Bosch Ridgid Ryobi Milwaukee Dewalt Worx Cut-Off Saw

Cutting action of blades is very effective.

I'd give these 6 stars if I could. These truly are miniature carbide tipped circle saw blades. Very strong & solid blade. Using my Dewalt die grinder, I cut some pine 2x4s and some thick wall PVC. Went through them like warm butter. Regarding the Arbor hole: The arbor I used fit very snug (at first) into the blade. I did some measuring and observations under a low power microscope. 3/8" = 0.375. My arbor is 0.3705. All three saw blades are 0.373, after cleaning out. The arbor hole on each blade had overspray on the entire surface, which will reduce the diameter of the arbor hole. The overspray is from either a sealer or the paint. Using a Q-tip dipped in 99% Isopropyl Alcohol it wiped off pretty easily. That may be all you need to do. It really does need to fit snug so you don't get any wobble. HIGHLY recommend!

On my m12 cut off worked pretty good. Had to sand the arbor hole a bit. Perhaps too much paint.

Have not tried them yet, but friends say t hey cut great.

Title says it all. These are not 3/8" and will not fit a 3/8" arbor tool. I suspect the issue is these are made in China and actually conform to the 9.5mm specification listed which is slightly smaller than 3/8". I assumed they would actually be 3/8 per the primary dimension listed and would also work on 9.5mm because that tiny bit larger would still let it work on a metric tool. Nope! These need to be flat listed as 9.5mm, period. I'm going to see if I can use a metal file to get me enough room to actually use these now that I opened the blister pack only to find out the dimensions are a lie. Real shame because they seem to be great blades otherwise, but when you're dealing with precisely machined dimensions you can't fudge things.

Work as intended for cutting in my Dewalt DCS438B. However, like a lot of other state, the arbor diameter is slightly too small. Says for 3/8" arbor (even printed on the blade itself). The arbor on the Dewalt measured .374". Tried a 3/8 drill bit though it to open it up still too tight. Really needed to use either a W or 25/64 bit. If I didn't need them that day I probably would have exchanged for a different brand.

I’m new to this stuff this is the third wheel I’ve gotten for cutting Masonite thin board.Hooray this 36 works as I was expectingThanks to other reviews I knew I would be too tight and you had to force it in the bolt but worked greatThe first came with my ryobi wasn’t something that worked googled to see what type to use next one too many teeth confusing writing had to run blade turned around to go right direction ? Burned its way through almost took brute force left super thick cut too

Be careful very sharp, my saw (with guards installed) still tried to grab my glove. While it only damaged a left glove; be safe on cuts
