Anyone know a supplier of medium to large hole saw bits that are carbide equipped for production use? I have a customer looking for custom tooling for 2" to 5" hole sizes and would love to point them in the direction of a "recommended" supplier rather than a Googled supplier.
Thanks for the excellent tip. I'm familiar with Hougen and Jancy and sent the customer to Hougen first thing. In fact, check out this video of our machine drilling a decent size hole through decently thick material. 2" diameter through 3/4" mild steel.

video is only just over a minute long so I'd have to guess it took 40-50 seconds total at most. I'll have to go rewatch it to see.
...It's the "birds nest" of chips that causes us a problem with metal. I'm not sure how their tooling would work in greenish pine.
