OSL312T 3-1/2 in. Starlock® Oscillating Multi Tool Titanium Bi-Metal Segmented Saw Blade

We chose this blade for the tile replacement we needed to do after removing an old vanity. The diamond grit would be a better choice for cutting a lot of tile, but we had some grout to remove and only one tile to cut. We actually ended up using the rounded side of the teardrop more than expected. We made the initial cut, and then five more passes to shave off a bit at a time until we arrived at the perfect fit. Before we cut that tile, we had used the pointed side of the teardrop drop to remove the grout from around all the broken tiles. Both sides of the blade performed their respective tasks easily… and the blade held up quite well. We should be able to use this blade for many years as the need arises. While the diamond grit is superior for cutting tile and the obvious choice for a pro, this carbide grit dual function teardrop blade worked perfectly for our needs. It’s a bit pricy, but so are Bosch tools. As they say, “You get what you pay for.” We confidently recommend this blade to other DIYers doing a kitchen or bath remodel needing tile work.

Have a kitchen remodel project that requires removing ceramic floor tile. Used one on an oscillating saw to clear the grout. Use a little spray water to keep the dust down and it works perfectly. Also trimmed another tile and got a clean cut. Tool is still in good shape so quality purchase.

Has worked well cutting plastic, wood and light metal. Has lasted longer than the standard oscillating blades. Only drawback is the blade does not have the C mount open for easy installation, you have to take your locking mechanism apart to mount the blade.

We have portable buildings behind our church. They have started to settle into the dirt and the doors don't close well. I used this to grind down the top of the metal doors and they close much better now! The teachers are thrilled. This is a good tool.

The carbide grit coating is only on the bottom of the sanding finger, but it works exceptionally well on wood surfaces. The wood fibers will cake on the tool, requiring periodic cleaning to maintain sanding effectiveness, but this is to be expected, and only takes half a minute, or less, to clean. If Bosch made these in multiple grits, I would buy one of each. I have no experience using this tool for any other application, so I can't make any recommendation for use on anything other than wood.

When it comes to removing tile grout there is no silver bullet. Anyway you approach it is going to be time consuming and laborious. I’ve tried the handheld tools with carbide blades....way too difficult. I used a reciprocating saw (sawsall) with appropriate carbide grout blades. This worked but the tool is heavy and cumbersome and there is a greater risk of damaging the surrounding tiles. On my latest project removing grout from a shower where the floor meets the vertical walls, I decided to try the Bosch OSL234HG. It fit my Rockwell RK5132K oscillating tool. An oscillating tool is easier to control and manage and is much lighter relative to a reciprocating saw. As with any cutting blade, it worked well out of the box. But I noticed after removing approx eight linear feet of grout the blade wasn’t cutting as aggressively and required significantly more pressure (and time). I’ll need to order another blade to complete the job. The positives about the blade is that it allows access into tight corners to completely and cleanly remove the grout. Again, the downside is that it dulled after about eight linear feet. My Rockwell tool can be speed adjusted on a scale of 1 to 9. I used the #4 setting. Ear and dust protection a must.

Better than I expect.

Does what it claims. Has a thin blade so I've no problems keeping in the grout lines of the shower tiling I am working on.

Smaller than advertised. This is a nominal 3” (70mm) and NOT 4” as shown on the listing. Otherwise it’s a quality blade from Bosch.

Maravilha de acessório para a Multicortadora Bosch.

Fantastic product. I burnt out multiple rotary carbide grout bits on one shower without putting a dent in even one line. I removed all of the grout from an entire 32”x60” shower, with a tile ceiling with only 1 blade. It cleaned well into the corners and to the base with no damage. You must be careful though as the crust on the blade is diamond and will cut the glaze and tile itself quite easily. I highly recommend this product

Easily cuts through tile glue and grout

Muy buena herramienta y sobre todo durable
