Review on 🔧 Carbide Burr Set TJATSE: 5Pcs 10mm Dia 1/4" Shank Double Cut Tungsten Carbide Rotary File Drill Die Grinder Bits - Ideal for Carving, Polishing, Engraving, and Drilling by Bernard Larjin

Summary: A very good set of carbide bits in a handy case. Recommendations: Let the tool do its job. If possible, fix the workpiece in a vice so that you can hold the grinder with both hands. I've used a lithium powered grinder and if you overload it the tool will shut down, which has happened a couple of times. For some materials like aluminum, also keep a stiff brass brush to clean your teeth when they become clogged. Pros: Various sizes/shapes; comes in a very nice, protective and handy case. Disadvantages: none. Verdict: $24 for 5 bits (about $5 per bit), 5 star rating.
