I'm planning on buying a T-Slot clamping set but after watching this video:

I'm a little worried that this type of T-Slot set will not fit on my CNC machine which is a hobby 6040 Chinese mill. I measured the gap of my slots and they are about 8.5mm which is not enough to get your finger in the slot as it was possible in the video. Looks like pro machines use bigger T-Slots. Can someone confirm that my suspicions are correct in terms of this kit:

CLAMPING KIT - 58PCS - FOR MILLING MACHINE T-SLOT TABLE #P07

most likely being inappropriate for my machine?

Better yet, if someone could point me in the right direction of an appropriately sized clamping kit, that would be even better!
