Review on 🛠️ HHIP 3900 5079 ER 40 Collet Chuck Drawbar: High-Performance Tool for Precision Machining by Adam Jackson

2 stars because the product photo and description is incorrect. I will change when the seller updates the product listing. Tie rod thread M12x1.75 (like most MK3 collets). It's not 1/2-13 as other reviewers have pointed out. - Machining is good, TIR < 0.001" - Uses a standard ER40UM nut (not the hex nut shown in the product image) - Wrench provided is a universal C-hook wrench (not a true ER40) - Wrong thread (3/8" -16) Laser engraving on the part - A few burrs around the threads
