Rear-Locking Slitting Saw Arbours you can Buy

Within my DIY slitting saw arbour video I mentioned I had ordered a couple of commercially available rear-locking arbours. Well they turned up about 10 days later and I show them here. They are nicely made, ground registers with 20mm shanks. These particular arbours accept 1" bore sw blades. They cost around £20 each with many vendors offering them for sale on Aliexpress - just search for 'Rear locking saw arbour' for the best prices.
