Most liked posts in thread: It's a drill Jim, but not as we know it

Really cool, but that takes pretty heavy duty industrial machines to use it - for example a 1/4" size hole requires 1.6hp @2800 RPM. Plus they're Morse taper toolholders, you can't chuck one of those into your home drill press.

While my little home drill press will hit 3,000 rpm, at 1/3 hp no way I can get the power needed to keep that speed when you start to press the hole.

Still, I'd love to have a 1/4" bit just to try on sheet metal - wonder what they cost?

 

They have a wizard to help you determine what items are required.

Formdrill: Tool selection wizard

As an example. For 1/4 NPT thread in 0.120 Stainless with a collar you would need these bits.

Very interesting but not something I could ever justify the cost.

 

And you need a Morse taper machine with significant HP to drive it.....

Those drive collars are spendy.....
