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

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

I use this for 3d print models no issues.

Update (10/12/20): Added a two way comparison to the solid aluminum handle version. The main difference is in the handle, the RED (or BLUE) one is solid aluminum, where as the Silicone (Blue/Grey) has a hollow handle. The solid handle is slightly smaller diameter, and maybe more comfortable for smaller hands. The Silicone is larger, which allows for storage of extra (and different) tool heads. The Silicone with storage would be useful for a field technician who might need different bits. Summary: I have had a few of these over the years, but this is the first one I have owned that has the smaller tip. Observations: Tested this by deburring the aluminum tube for a car wash kit, that had really sharp edges, enough to scratch the inside of the corresponding handle. I was even able to debur the small 1/4 (6mm) detent button holes with the small tip. Recommendations: Take your time, dont take off too much material in a pass; vary the angle to remove different amounts of material. Pros: Good fit & finish; lifetime supply to replacement tips; storage in the handle; the tip release works easily. Cons: None. Conclusion: At $16, this is 5-stars.

Awesome tool for resin work

great for cleaning seems on 3d prints.

Great tool. Fits comfortably in my hand. Havent had to change the tip yet after deburring a lot of copper pipe (type L). Have used it on as small as quarter inch up to 3 inch pipe

No handle supplied that fit these tools.

Feels good in your hand. Debuts 3D printed parts with ease.

Epoxy edge trimming

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.
