Review on 🔩 Rocaris Double Cut Titanium Carbide Rotary Burr Set – 10 Piece 1/8"(3mm) Shank and 1/4"(6mm) Head Size Tungsten Steel, Ideal for Woodworking, Drilling, Metal Carving, Engraving, and Polishing Tools by Adam Rogers

I bought these to use with a Dremel tool to trim the edges of a Japanese racing radiator cap to match my Chinese POS Mishimoto aluminum radiator and its inadequate aluminum cap (for my Dodge Ram 3500) fit, which was complete crap! This cap is designed and manufactured to company standards. The new racing cap is made from an alloy that is stronger than aluminum and these bits gnawed the deep edges of the cap down to just the right amount I needed to mount it on this radiator with its wide entry lip. My advice: NEVER buy anything from Mishimoto, it's just a big Japanese marketing scam.
