Use router bit in a drill press?

[threesixright]

Is there any reason why you could not  use a (8mm) router bit in a drill press?

I don’t mean just any router bit, but those used for drilling holes.

Reason asking is that the RPM of the drill press is way lower, not sure if that impacts the performance in any way?

I expect it work, just checking ...

I'd expect it not to work, due to chip load and cutter flute geometry. I'm far from an expert on this but with limited experience with speeds/feeds and chip loads on CNC machines it just seems to me like it'd be problematic. Hopefully someone with more expertise will weight in.

Post your outcome, I'd be very interested in seeing how this works.

Thanks, I will take a piece of scrap wood and just compare the 2 methods. Will post back the result here.

I only need to counterbore a few screws (only 25mm), its only a 2 mm depth. Now the beams are over 3m, pretty sure to bring the router to the beam. Yet, curious if -for smaller pieces- a drill press would work.

You intend to use an end mill?

No for sure not. Im just need some clean holes dor counterbore. So nothing “pushing” against the spindle.

My only concern would be the speed. My OF 1400 spins so much faster then the drill press.  And the spindle has less play.

I’m curious if people would use these type of router bits in both type of machines. Maybe its a really a big no-no...

The bugaboo with using spiral router bits or end mills in drill presses is the hardness of the shafts on the tooling. That's the reason they are used with collets. They will easily spin in a drill chuck if there is any large amount of resistance. You may get lucky if you're drilling wood and you aren't going too deep.

Certainly a spiral/helical cutter would prove to be a better choice than a straight knife bit because of the chip loads.

I'd start with "pecking" the router bit. Bringing it up to it's desired rpm and then bringing it down into the wood just a little bit and then bringing it back up...up & down...up & down. This diminishes the chip load and cleans out the bore.

A drill bit is actually soft and allows the drill chuck to bite into the drill bit shaft.

Thanks!  This is some good inside, didn't thought of that. I only need to go like 2mm deep, so I'm guessing it will be alright. But thinking about this, I got more curious wetter you could use this a replacement (hence the question). So drilling much deeper then the 2mm I will not do. I will post some pictures for comparison (how clean the counterbore is).

I use router bits and end mills in a drill press often. They work just fine, never had a problem.

In hardwood using a router bit in a drill press would be advantagious, b/c with the lower speed they won’t burn as easily.

I don't see a problem drilling with a router bit designed to drill. I would point out though, side loading a drill chuck will often dislodge it from the taper. Don't ask how I know that  [scared]
