Review on 🔧 Parabolic Jobber Drilling Bits - Max Power Degrees by Shigg Bigbee

In my drawing, the left hand silver bit shows a properly centered split point. The faulty ones I received are on the right. Everything I have is useless to me. I use them on my CNC lathe and they don't drill very deep so they break. UPDATE: I checked all split points under 10x magnification. All bits have cracks in different places, there is definitely a problem in both production and quality control.
