Just quoted a job that needs a diehead and a rotary broach to make it worth doing. I green to both tools. I did purchase a Taco Diehead that is the size I need for Ebay. But a I have not found any info on a rotary broach. Any advice?

"PracticalMachinist.com"
I get very little feedback from that website. So I thought I would try here.

Lots of variables to Rotary Broaching", best to call a manufacturer on that, it is not inexpensive.

Looked into it and they were very helpful.

I contacted http://www.rotarybroaching.net/

Do a search on rotary broach here in archives. Frank Ford posted a very well documented (as always, with the best technical photos on the board) article on making his own rotary broaches. Hope this helps.

I took my own advice and couldn't find the post I just knew was there. So . . . I surfed on over to his website and got the link. Here it is, hope this helps more.

Thank you
The link to how to make a rotary broach was awesome. I had been thinking if that would be a option I only have to make 5 pieces in 303 SS, with a 3/8 Hex broached.

I have a Slater rotary broach. Here is a link to a video,

They work well and are very fast but expensive.

You can rotary broach directly using the broaching tool by offsetting your tailstock and hand cranking in. Slow compared to using the special head/tool holder, but works if only a few pieces to do.

Nice tip! I've been wondering how well that works.

3/8 hex in 303SS,factoring in the cost of head and broach, you should have quoted about $150+ per hole. Unless you're counting on many more similar orders it would be best to farm the broach work out.

Don't forget blind broaching can be done just as easy or easier in a press.
