Oscillating Tool Blades, 6 Pcs Oscillating Multi Tool Diamond Segment Swing Semi Circle Grit Grout Mortar Removal Saw Blades (6Pcs)

This fit my oscillating multi tool from Harbor frieght. For less than the price of 1 blade, I received 6. Very happy with this purchase.

The oscillating tool blade is tough, use it to shovel bathroom grout. It was removed very cleanly.

Use these for clearing out some grout lines that were starting to chip out. Did a nice job and fit my Milwaukee multitool with no problems.

Gearing up to regrout our second shower. I did the first one with a hand held grout saw (took me three days) and decided that the next shower would be done with mechanical tools. The grout is over 30 years old and hard like rock. So I bought an oscillating tool and these diamond grit blades. First thing I did was check to see if they fit my tool without the need of an adapter. If not they were not going to work for me. Great news they fit my Milwaukee M12 multi tool, no adapter needed.Just need to design a jig so I don't cut too deep as these blades look like they're going to cut very aggressively. Old eyes and shaky hands with an aggressive tool could lead to disaster with out a proper jig.There are six blades included with the set, three half moon shaped ones and three sort of boot shaped. There is a good amount of the cutting grit (diamond?) on the blades in a chunky pattern. This is like extra course sandpaper and should work well in removing the grout. The long boot shaped blade showed no "wobble" when tested. The unknown is what type of bonding glue is used and wether it will be strong enough to hold on to the diamond grit. Slower oscillations might be the key to longevity, but there are several blades and they should cover the job. Overall the right tool for the job. Now about that jig.

Works very well with Dremel Multi-Max 6300. As with all universal blades I've tried, these don't line-up perfectly centered with the tool, but are close enough to not be a problem (unless you're working in an extremely confined space). The blades easily cut mirror glass, and also helped to smooth edges.

As a graduate degreed engineer I very much appreciate well designed tools and as the owner of a handyman service I also appreciate well priced tools, especially if they're "consumables". I've used quite a lot of similar diamond grit oscillating tool blades in my business. Whether expensive name brand blades or unknown brand blades from Amazon all seem to be of similar quality, cut about the same and are of similar durability, but the costs of blades varies wildly. These particular blades are both good quality and a bargain price.I just used these to cut grout from between bathroom tiles, a job they're designed for and excel at. The blades are quite durable when removing grout, since grout is relatively soft and chips apart relatively easily. I've seen people try to use this type of blade to cut ceramic (or even porcelain!) tile and complain when the blade wore out quickly, but these blades were never intended for a task like that. Diamonds are hard enough to cut through most anything, but the glue attaching the diamonds to any similar blade has only so much strength. Use these for appropriate tasks and keep the heating of the blade in use under control (excess heat loosens the grip of the glue on the diamond grit) and this type of blade, and these blades in particular, will last very well. Note that an oscillating tool rubbing these small blades back and forth across some hard material like tile will heat the blade up surprisingly quickly. By the way, the similar name brand blades available at my local big box home improvement store are similar (identical?) in quality, but cost 3-4 times as much.

Sometimes I need to cut through nails, concrete and who knows what. These blades don’t mind surprises, and will cut through almost anything and keep on cutting. Great blades.

I got this set of oscillating blades for a small tile repair job in our bathroom. It made very easy work of cutting out he section of grout I needed to remove and I liked that I had different types of blades to use. The blades all seemed to be high quality and durable, and I'm confident they'll last me a few more projects. This multi-pack was less than the cost of buying 1 blade at my local hardware store.
