    ATTACHMENTS + OTHER TOOLS | FOREDOM should be under $500 depending on options. You would have to take the guard off to get 3" but you likely don't have one now.

    Tip or insert? SumoCham? Which tool exactly are you using for the first material? Could you use the same tool all the way through just changing speed and feed? I bet a SumoCham ICP would make it....

    Never messed with stuff like that but I wouldn't use 2 brands for the same hole. The reps will just blame the other brand (likely both rightfully so). Pick one brand, have the rep come in, and tell...

    Do you have it on during the whole cycle? Pick one operation or tool to have it on and off the rest of the time. The chips need some time to drip dry before going in the bin.

    You don't think you could correlate the double shear in a standard fixture to the single shear in your application? It might not exactly be double shear x 3 / 2 but there is likely a coefficient very...

    I think the requirement for a special shear fixture is what the problem is. There are already 2 standard fastener shear types out there. I'd suggest double shear per NASM1312-13. There are many test...
