Jointer wrench size?

[Jim Dunn]

I have an X5 6" Delta jointer. I need to adjust the knives. Using the tools supplied with the jointer I don't seem to have the right size wrench. The set screws that hold the knives tight are supposed to be 8mm. I base that on the fact that I don't have a 9mm wrench. But the 8mm is to small.

Anyone with this type of jointer what size wrench do you use to loosen the knives for adjustment?:confused:

Jim, don't know if it will help with your jointer but I have a DJ-20 and the wrench I use is 10mm. I had to grind it to make it thinner as it would not reach down between the holding-plate and the meaty part of the cutterhead. It did not come with the jointer, it is just a regular wrench.

Hope it helps.
