-for advanced/pro’s only *removes a lot of material very quickly
-6” long, can be cut down to whatever length works for your particular grinder and/or work piece
-designed for maximum material removal while still keeping a smooth surface on aluminum
-for use on aluminum only, not steel
**Not recommended for use in a hand drill, or any equipment that is NOT a dedicated die grinder, HeadGames burrs are designed to be used at minimum 5,000rpm and maximum 28,000rpm.
Dave’s take- The 5/8 burr is a game changer!  I use this burr for pocket ports, and full ports.  You will be very impressed with the amount of material it removes while still keeping a semi smooth surface.  I use it at full speed (20,000-28,000rpm) to rough something in, then grab my HeadGames 1/2 super spiral burr, turn the speed down to half and fine grind with it to a smooth surface (that makes sanding easy).  If it will fit in a hole I try to use it because it makes moving material and shaping so effortless.
