Review on ๐Ÿ› ๏ธ YUFUTOL SC-5L6 Tungsten Carbide Burr - High Performance 6" Double Cut Carbide Burr File for Precision Finishing, 1/2" Dia X 1" Length Cutter, with 1/4" Shank Dia Cylinder and Ball Nose Shape, 1pcs by Andrew Agarwal

Revainrating 5 out of 5

ported my intake manifold with it.

It worked great to get into my intake manifold fittings. A note: if you are grinding aluminum you will need to spray the drill bit with lubricant. WD-40 works great. If it's clogged with aluminum, just dip it in hydrochloric acid and the acid will eat away at the aluminum and clean out the boron.

Pros
  • Multifunctional
Cons
  • Definitely bad product
