MAVAST Silicone Deburring Tool with 21 High-Speed Steel Blades Blue

There are no instructions with the tool. It should be easy to use; however, getting the head of the blade out is a little dicey with having to pull it on the sharp end of the blade. When using the blade it rotates and sometimes not in a good way. Should be more stable.

These are super handy to have for finishing 3d prints. The blades will last forever when theyre only digging into plastic. Less so of course if you finish copper or steel. I couldnt be happier with this.

No handle supplied that fit these tools.

I understand that this is to help shave down cut pipes so that they are round and dont have little shavings/cut pieces inside your pipe. I used this for my resin work instead. This easily helps me cut off small pieces of resin that I have poured outside the mold. It easily cuts off parts of resin and helps smooth it out. By using this instead of sand paper it saves me so much time and work and keeps my resin looking lovely. This fits well in my hand. This feels like it will last a long time. Its easy to use. I like that it came with extra knives. It is easy to change cutters.

I received this product in exchange for my honest review as part of the Amazon Vine Program. Seller MAVAST lists this as MAVAST Silicone Deburring Tool with 21 High-Speed Steel Blades Blue. This tool is for those times when I want to smooth the inside of small soft metal tubing (silver or copper). The head allows the shaped curved hardened steel deburring knife to swivel 360 degrees as it drags and cuts off burrs to smooth the surface edge being deburred. The knife is easy to replace; press the collet collar towards the handle and the deburring knife drops out. The handle has a plastic top that can be twisted off to store knives inside; I prefer the small boxes provided. Picture 1 shows the tool package and 2 open boxes of 3 varieties of deburring knives. Picture 2 the top off. Recommended for basic soft material deburring needs. I found this to be a good value with all the deburring knives provided.

After discovering these are used to clean up the edges of 3D prints, I started looking for one. This seemed to be reasonably priced, and had a few different blades. The blades are excellent. The tiny tip and regular are all that are needed for any of the 3D printing materials, so I cannot speak about the blades specific to stainless steel; They are shaped and perform identically to the regular blades. The tiny tip blades are good for getting into small holes/spaces, but they tend to dig into the part more than the regular blades on larger radius and square/straight edge parts. The handle is large and comfortable, but sometimes gets in the way in tight spaces. Smaller diameter handles are available, so I plan to purchase a set with the smaller handle, whenever I need to get more blades. Because I am working mostly with soft materials, this may be quite a long time away. Thank you, MAVAST and Amazon, for sending this tool for honest review. I hope everyone finds it helpful.

This little thing is awesome! Super easy to use and comfortable to hold/grip. Cant say Ive ever used a different brand, but if youre debating between names, this is the one.

this works well, but after using it for a variety of different materials, I feel it isnt intended for heavy duty use. The metal body versions might be better suited for stuff like exhaust pipes; I was able to get it to work, but I got the feeling that if used to hard, itd break just above the collet. no complaints though - it works & was inexpensive

Bits do the job well that come with this but the handle is rather lame and just not sturdy.

It works as promised. I havent used it much. but I was impressed with the speed, smoothness of the trim and efficiency of the tool. it is a great value for the money
