Review on High-Speed Plastic Titanium Drill - INTOO by Alex Montgomery

These drills are by far the worst drills I have ever used. They COULD work well for styrofoam, but for anything more complex forget it - you're better off using an appropriately sized hammer and nail. I've used this on plywood - pushed, pushed, pushed, and after 30 seconds I finally had a 1/2 inch deep hole. I have a 3D printer. I tried using them to drill through PLA (the plastic used for 3D printing) - couldn't even drill a hole with a 3mm drill bit, had to start with the smallest drill bit and work up to 3mm. I took an old 3/16 (5mm) drill bit that I have - 3 seconds and done. AVOID THIS unless you are serious about isometrics.
