Rockwell RW8924 Sonicrafter Carbide Grit Finger Rasp Blade with Universal Fit System

the slots are 1-2mm too small to fit my dewalt multitool.

Amazon review 7/15/2022 for the Rockwell RW8924 Sonicrafter Oscillating Multitool Carbide Grit Finger Rasp Blade with Universal Fit SystemIf you have a wooden door that sticks a tiny bit on the threshold, this rasp attachment for a multitool may allow you to shave just a bit off the door w/o removing it from its hinges. You need very little clearance with the floor and a regular multitool with this bit will usually work just fine. Please note that this idea only works for a slightly sticking door. If you need to cut 1/8" or more off of the door, remove it and use a different tool.

Very useful blade for an oscillating multi-tool. Works well against green concretes and mortars but will still knock down fully cured stuff, the blade just won't last as long. It is well covered with carbide and ready for the long haul. I used mine heavily on a home remodel that involved a fair bit of masonry and mortar work/ rework. The blade did not last forever, but I never expected it to. Nevertheless I bought two more, one to finish the remodel job and one to have ready in my toolbox.One of the big reasons Oscillating multi-tools are so amazingly useful is in how you can quickly change the purpose of the tool, sometimes quite drastically. This is one of those blades that offers you some of those crazy uses if you keep this in the tool bag. One good example would be my remodel when I was laying tile. Using a particular tile leveling system, I would sometimes need to carve out a niche in the old thin set for a leveling clip. When green the thin set could be carved out with any metal tool, but once cured would require a power tool. While laying tile I could quickly change from using the tool to carve those niches to using the tool to cut out doorway framing for the tile to fit under.You may not need this blade tomorrow, or next week, but when the day comes that you need to quickly knock out a bit of mortar or concrete, you will be glad this little dude is sitting in your toolbox ready to go.

Great tool for aggressive cutting of wood surfaces, and both top and bottom of the tool surfaces are coated in the carbide grit. If they made these in multiple grit sizes, I'd buy one of each. I haven't tried it on anything but extremely weathered wood, and it worked great, so I cannot make any recommendations on other applications.

Lasted about an hour. The tip coating, on both sides worked but then disappears.The tip coating is to wide and damages the tile. Now I’m searching for replacement tiles,not doing the job. Ridiculous

Five stars
