That tip is knackered, replace it. The hole is worn unevenly and will affect you getting a clean square cut.
Your inner tip will likely need changing too.
It's important to keep the tip clean. Use a wire brush between cuts.
The hole in the tip is important. If it gets to big it will not cut properly and off square.





) and a replacement matching part number starter is £50+ which isn't needed as rest of it still works though there is newer engine ones which are £30 but probably won't fit due to different tooth count.
