Customer Questions & Answers

I'm removing and replacing all caulking in my bathrooms and kitchen would this tool achieve removal safely and effect.?

Of course removing old caulking takes longer than any other part of the job. I have tile, fiberglass, Formica, and linoleum surfaces to remove caulking from. Help a rookie looking for a smoother more effective way to perform task?
Asked by: Bonehead
No, The oscillating head could chip tile. A good old fashioned utility knife and sharpened 1" putty knife is still the best option.

Multi-Max Multi-Knife is rated 4.6 out of 5 by 15.
Rated 5 out of 5 by from Awesome for roofing Scoured internet for alternative to manual hook knife for cutting asphalt roofing shingles and barely came across this item. When I check Dremel website, it barely mentioned roof shingles so I was suspect it was really designed for this but tried. WOW! This cut 30 yr dimension asphalt roof shingles like butter! Had to do more than 250 cuts and the same blade cut as fast as I could setup shingles. Best solution for trimming installed shingles on roof. Very few local stores carry and very few people know about this on internet which is a shame. if this cuts asphalt shingles this good, I trust anything else would be cake. This is the best blade since the diamond sanding blade!

Rated 5 out of 5 by from Works Great! This Dremel multi-knife is a handy addition to the tool box. I don't have this brand of oscillating tool, but with the inexpensive adapter (MM300), this knife will fit other brands too. So far I have only used it to cut up stacks of cardboard boxes in the garage. It made the job so much easier than the struggle with the old utility knife, I'm impressed! I'm sure that cutting the carpeting we have to install is going to be a breeze! The blade is very sharp, and it comes with a handy soft plastic sheath to cover the blade when not in use. I like the double hook, giving you the option of using either a push or pull motion when using it.

Rated 5 out of 5 by from Very handy for carpet I used this multiknife to cut old shaggy carpet in my son's room. It is much easier than useing a claw knife and zips through the strings, cutting an even line. This is very helpful when I want to remove carpet in small sections at a time. You can use the knife to cut in both directions, pulling it toward you or pushing it forward. There is a sharp point on one end, which is handy in starting a forward cut anywhere. Since the point is sharp, I usually attach the knife with the plastic cover it comes with until it is securly on the tool and then cover it again before taking it off. I would also make sure the power supply is not connected when removing it since not all multitools have this safety feature.

Rated 4 out of 5 by from Cuts well but box cutter still faster for some uses The Multi-Knife is a good attachment to have on hand. It cuts very easily with either the hooked side of the blade or the straight. Does plunge cuts well. This item will certainly save time cutting material such as carpet or linoleum. If you are breaking down cardboard boxes that aren't oversized and only need to cut the tape, a box cutter is still much faster (no cords, fast swipe and down). If however you have a large box that needs additional cuts or is of thicker material, the Mult-Knife is the way to go.

Rated 5 out of 5 by from Alternative to a utility knife I don't have a Dremel oscillating tool, but it fits great with an adapter. Mine cam with on so it can fit on just about anyone other there (check before buying, not sure on some of the newer tools that have tool free release mechanisms) I used this to cut up some cardboard boxes so they fit into the recycling bin. Worked really well on the thicker glued together sections. Made it easier then using a utility knife, plus there is a lesser chance of slipping and cutting myself. I am sure it would help in removing carpet.

Rated 5 out of 5 by from You can even do plunge cuts I had an unusual job for this knife. I needed to cut in a floor outlet in a carpeted floor. I have done this before with a razer knife, but it is not fun. With this knife, and the tool at medium speed, it was a snap. The push blade works well for starting a cut in the middle of the carpet, and the hook works well for completing the cut. You can use the push blade for the entire cut, but I like being able to lift the carpet as I cut. The hook end lets me do that. I stop the cut before finishing the cut, and change back to the push blade for the corner. I feel that it gives me better control. The push blade also does a nice job of cutting other types of installed flooring. I am looking forward to using it for trimming the next time I install flooring. It should work out great for trimming around cabinets! One thing to be careful about - the blades are SHARP. Make sure you wear a good pair of gloves when using it!

Rated 5 out of 5 by from very handy attachment This tool slices through corrugated cardboard like a hot knife through butter - faster, easier and safer than a box cutter or utility knife. I kept it on my oscillating throughout the holiday season and every time a box showed up, I quickly cut it down to easily recycled pieces. Fun, actually. I also tried it on carpet and floor mats and it was similarly effective.

Rated 5 out of 5 by from Very Sharp - Good for odd cuts. We used this to cut a large rubber mat down in size to fit a dog kennel. We first tried to cut the mat with a pair of snips and then with a sharp knife with no luck. We had just got this in the mail and decided to try with the hooked edge of the tool. It cut the mat like it was cutting cardboard. Very handy to have and easy to use.
