Review on POWERTEC 4 Inch 20 2 Inch QTB1005 T Slot: A Revolutionary, High-Quality Power Tool Accessory! by Vincent Blitz

Sockets slightly oversized. So far, it's better not to rack your brains! I have four different tracks I use them on and they don't match any of them! The caterpillars also vary in size, being too wide for some and fat for others. It's annoying, but it's no big deal to touch the grinding wheel to adjust it. There's a lot of metal, so there's no loss of integrity. What makes me wonder is why that is. I have several other T-Bolts in the kit from Powertec and they work great on all my tracks with no modifications.
