Carbide Burrs Set 5pcs Extra Long Shank Carbide Rotery Burr File Double Cut 1/4 Inch Shank Long Burr Bits For Die Grinder Bits

These bad boys will grind fast and efficiently! I used them on an aluminum plenum for my engine. Because it’s aluminum i had to use a wire wheel to remove the aluminum from the bits which is normal. The bits stayed sharp even after using the wire wheels on them. I would definitely recommend these!

Like this set! The extra length really helps when getting into hard to reach places. Used to widen holes or grind down ‘snot’ welds on the old car in restoring.

I had to machine the shank down to 6mm from 1/4” they are good quality and work well

I bought these to port some aluminum heads, cleaning up the non Ferris burr cuts. I am impressed with the quality, the shank is strong and the burr cuts mildly well, not quite as great as a high quality bit though

The media could not be loaded.  Excelente lo que buscaba

3 out of 5 bent

this is how they compare to regular length ones, hope that helps someone, also one broke in less than 10 minutes of use not abuse while I was trying to grind down part of a weld, I was simply just allowing the tool to do the work

these bits melted through hard steel like butter. still very sharp.highly recommend
