Review on 🚀 SPEED TIGER Carbide Square Mill Cutting Tools: Precision and Efficiency Combined by David Monaco

I have used and abused this drill bit to cut and route 2 lower AR receivers on my drill press. At the end of the second he started to blunt. However, I abused it when cutting aluminum and it worked really well. Remember that you will need to increase the speed of the drill for it to work properly with these bits. Much of the material has been removed to complete 80% of the receivers below. I would recommend and will definitely buy more for future builds. I had no problems with it breaking, luckily I only had one. Also the length is great for the work I did.
