Drag Knife Speeds

[bigjeff (Jefro)]

I am getting a drag knife for my shapeoko pro to cut rubber (2.8MM) and vinyl. Was wondering if someone could advise me on speeds and feed?

Perhaps the feeds and speeds which we use for the Stingray will be a useful starting point?

New Product: The Stingray Drag Knife

Another new product to announce before @Luke can get to it, the Stingray Drag Knife. You can see it at: I’m sure there will be more to add to the product page based on the discussion here so if there are any questions, ask away and some combination of @Luke , @wmoy , and @KevBarn14 can jump in with some answers.

Well, speed should be zero. Feed is what you want to set and you should do some experimenting with your material to see what works. I would start sorta low, like 35ipm or so and see how it goes.
