when starting with a broken or cut drill bit i usually grind it , just to help the Drill Doctor a bit so as not to dull or wear out the diamond wheel in it. ( itll probably make the Drill Doctor last longer). Ive done it and works just fine using my method folks.😉
💥💥 Thank you for this great video. It sounds like the motor almost comes to a complete stop every time that the bit contacts the grinding stone as you rotate the assembly and I’m wondering if that’s what is going on. Also do you know how this model compares to the 350.?? Much appreciated 🤟🏼
