Sounds more lihe you have the tools in backwards, can you post a photo

Should look something like this

Be carful if you run it backwards as on a lot of the imported ones the head screws onto the shank and will unscrew if run in reverse

Just noticed that RDG sell normal and "opposite hand" sets of tools. Did you order or have you been sent the wrong ones?

The brazed ones can be reground no matter what hand they are, just grind the curved surface until it is straight. I have done this on a few cutters for when I use the head to turn external diameters rather than bore holes

Why is that Michael, I use the same tools for both. Don't have left hand drills or milling cutters when milling horizontally (or using in the lathe head)

You may certainly machine the outside of a boss with a boring head with opposite handed tools.

another Martin

I have done it a few times on things that were too big to swing in the lathe, the two bosses that locate in the hortnplates on these castings were too far apart to swing on the lathe

also used it to cut cams with radiused flanks.

But the job that I use it in external mode for the most is making oval steam bosses and glands. This is just one of the conventional hand brazed bits that I have ground the curved surface flat on so it can be used either way round.

Hi, I have used a boring head in reverse, as I had no tools for using it in the normal direction. My solution to the problem of the head unscrewing was solved, by drilling and tapping the head for a grub screw **LINK** worked OK for me.

Regards Nick.

Thanks Mike I did twig when I saw DrDave's post, I thought you meant when the mill head was used horizontally not the horizontal hole.

Though if a through hole it is possible to cut upwards with a RH tool if the job allows.,
