💡 What advantages does a dedicated knuckle puller offer compared to standard vise mounted setups?
- A focused lever action drives the insert evenly into the hole without distorting fragile sheets
- Swapping out the correct die head guarantees smooth internal threading across different material densities
- Catching the spent arbor by rotating the top knob stops binding and clears jams right away
- Stocking several thread diameters keeps any sheetmetal repair much more handy for weekend builds or daily trades
