Review on 🔩 High-Performance FTG Parabolic Replacement Countersink Tapered - Improve Precision and Efficiency! by Russ Montgomery

Don't send our money to China again. This is a scam as they are printed from the USA. Spend extra money to find American beats. The quality sucks. Great for imprecise work, but if you need the hole in a precise spot you will need to pre-drill. In a lathe chuck you also need to pre-drill. Otherwise they wobble, heat up and break off.
