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

It does what it says. Quality design and the attachment fit securely in the handle with easy removal. Makes an easy model clean up for 3D prints and is much safer than using a knife.

Use one blade for aluminum, one for steel, one for stainless etc. switching back and forth will destroy the edge. Don’t pull toward your hand/arm. The blades do slip off what you are deburing

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

This is an easy tool to use. It safely removes burrs and sharp edges from inside copper tubing and other inside edges in harder metals and plastics. Inexpensive and comes with plenty of replacement tips

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.

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.

great for cleaning seems on 3d prints.

Works as it should

Havent used it but what I was looking for for the price.

I’m an electrician and I use this to round the edges of my panels so there not so sharp to cut peoples hand on!! Blades last a long time!!
