I have a grizzly 8” jointer with a helical cutter head and I need to rotate a few inserts. I can’t get the screws to budge. Suggestions appreciated.

I've read where some put the right size bit in an cordless impact driver. When you do get them out, put a dab of antisieze on the bolt before reinstallation.
I read in a Powermatic manual (may or may not apply to Grizzly stuff) that some of their cutter heads use a T25P not a T25 Torx bit. If you have the T25P style screws a T25 will fit but as Powermatic warns "A T25 adaptor or drivercan round out the screw head recess. Alwaysuse a T25-Plus driver or adaptor." I don't know if this is a Byrd thing, if they still use that style screw, or if the people who make Grizzly tools also use them. Just an FYI.
If worst comes to worst break the carbide to relieve tension on the screw. Consider replacing the China made screws with proper USA, Japan or Europe made screws. Before breaking the carbide I would hit the screw head with a torch and oil a few times.

Byrd’s instructions clearly call out T25 plus; https://storage.googleapis.com/wzuku...20rotating.pdf
I don't have one but I thought I would point it out. I'm not sure how easy it would be to tell the difference. I have never dealt with the "plus" style Torx heads so I don't know if the standard Torx bit will fit but is just a bit loose (my guess). If you're using the supplied tool it shouldn't be an issue. If not and it requires the T25P bit then I would invest in a couple of spare bits. You might want to get a torque screwdriver. Maybe not a Mountz but one to help put the screws back in at the correct torque.
A little heat from a soldering gun wouldn't hurt...
Success. Used bit that came and attached to long handled screwdriver. Thanks for help.
Sometimes that's all it takes is more torqe. If you ever do need to break an insert to remove screw wear safety glasses. Carbide can shatter and send small fragments flying like z bullet.
What is a Torx plus driver and how does it differ from the garden variety Torx?

The Torx Plus has more rounded edges on the points of the bit where the normal Torx just has points on the ends of the tips.
