Review on πŸ”§ SM-5 25 Degree Pointed Cone Shape Tungsten Carbide Burr File (1/2" Cutting dia X 1" Cutting Length) - High-Performance Tool for Precise Metal Shaping - 1pcs by Dusty Tofte

Revainrating 2 out of 5

Waste of money - the drill head had to be sharpened to this angle!

It's endless sticking with aluminum while trying to create a countersink at the right angle. I would never buy one of these again and instead just use a grinder to get the drill bit the same size. Maybe that's good for wood or plastic, but definitely a disaster for aluminum.

Pros
  • Great design
