Review on 🔪 Enhanced Precision with Zenith Industries ZN103111 Carbide Tooth: Unleash Unmatched Cutting Efficiency by Richard Sallah

I just received this drill bit and used it immediately to cut 24 holes (1.25" diameter) in 1/4". to drill steel. The chisel worked great and feels just as sharp as it started. I used a small (5 amp) drill press running at the lowest speed and I could use a little more power but it did the trick if I was careful with the feed pressure. I also used a lot of oil.
