    Broaching with Hexalobular Rotary Broaches

    I need to broach a T25 hexalob anyone have any experience with this. From what I read it seems as though it can be difficult. I will be able to cheat a little on my hole size material is 1144. I will be running 1000's of parts will the broaching not be an issue or should I consider milling it. Machine is a Citizens A20 will be broaching on the main spindle

    I haven't done any hexalob's just regular hex's a lot of them in 4140 with no problem
    Genswiss might be able to help with broaches and drill size and rpm for you

    Also check out Polygon Solutions. They make some nice Swiss sized holders! Very helpful as well. Make sure your Toolpost, or GDF block is centered really close! ----------------- John :cheers:
