Bosch OSL138K 1-1/4 In. Starlock® Oscillating Multi Tool Hook Knife Blade

This blade works wonderfully cutting shingles, cardboard and everything else that has been put against it. It is sharp, keep away from things you don't cut. Easy removal, cost effective, smooth use, and much more comfortable for long applications compared to utility knife holders.

Cuts through cardboard like butter. Super easy.

Cuts heavyweight industrial cardboard like butter. Way overpriced.

Useful blade for scraping caulk and other items off of flat surfaces

This was a special needs case. It does trim roof shingle well.

I needed to recut a roof/wall intersection in some old architectural shingles. Two roof/wall transitions, I did the first one with a simple saw blade in the oscillating tool. It took a while and I worried a little that I would cut the step flashing (though it's galvanized). All of the teeth were worn off on the first shingle and cutting 10' of valley took 1/2" off length of the blade. That wall took an hour or so. So, I bought this blade for the other side. Wow, 10x as fast. Slices right through the shingles, asphalt, fiberglass and sand. I did pretty good at lifting just as I came to the bottom of each step (cutting up - trust me) but when I did catch a step, this blade would not cut it at all. I'm confident that I did not damage the flashing in this little adventure. Got that side cut in 10 minutes. The blade appears to have not worn down at all. I also tried this blade on some cardboard since it says it's for 'soft materials'. Cuts cardboard like buttah. I will say though - you want to know where your fingers are when using this particular blade.

This works when you have a long, straight, wide caulk bead to remove. If the caulk bead varies in thickness, as in the bathroom I just completed that had caulk inside irregular grout cracks, you may not be able to fit this tool into the crack. If you do have that long, straight, wide caulk bead, this will work well. It can be mounted onto any brand of oscillating tool with no problems. Be patient and go slow. Keep the flat side firmly against the edge of the caulk bead.

I recently saw a YouTube video that demonstrated the use of this blade for cutting cardboard; and I was amazed. I searched it out here on Amazon, and found this one for my star lock connected Bosch multitool. I couldn’t be happier. Overall a very useful blade that I’m glad to own.

Good

Lasts long and great for removing caulking

Très satisfait

Would like it to be a tad more flexible but otherwise good

Quality Bosch blade for the starlock fit. Handy accessory blade to have when you need it.
