Thread: Boring bar
21/10/2019 21:56:22

Hi

Thanks to all who have replied. It looks like one of the cheap Chinese boring bars maybe the way to go as although I now know which insert I need I cannot find anywhere that actually sells them.

Cheers

Hi

Unfortunately not as it disappeared and the piece left in the holder was so small you wouldn't be able to get any information from it.

Hi

For years my father has been building engines and repairing clocks as a hobby. Unfortunately he now has Alzheimers and I have been trying to help him finish an engine he started a few years ago.

I have managed to break the insert in a boring bar and wondered if anyone might know where I can obtain a new insert from.

The boring bar has the following number on it UJ 8-803-F-R, the insert is triangular, held in with a very small Torx screw. Measuring the size of the recess I think it would be around 5.5mm across.

I haven't been able to find any information by searching for the reference number on the internet.

Below is a photo of the boring bar. The key is there to stop it rolling so that the number is visible.boringbar.jpeg

Any help would be appreciated.

Cheers

Paul
