Drill Bits?

I am wondering if regular drill bits can be used in a router? I am using a spiral bit and it works really well for drilling a hole but the size is quite limiting.
Thanks for any suggestions/answers.

Welcome!
I wouldn't use a drill bit in a router. They aren't designed to spin that fast. Not sure they are made to the same material tolerances as a spiral bit.
Larger holes can be made with a router using any number of jig/bit configurations.

I was going to question why you would use a stub drill Peter then I realised that in Croatia it's a case of necessity being the mother of invention!

As has been stated, twist drills are not intended for use in a router, you can however use end mills and slot cutters but of course there is no substitute for a cutter made specifically for routing.

Not that, Harry! Rigidity ! Stub drills are intended for rigidity. I wouldn't have risked it with the normal length of a jobber drill, which could have whipped.

The idea was that the router, with its guide bush, together with the jig, enabled precision placing of the holes. The spiral of the drill, as drills are designed to, clears away the chips. It didn't seem revolutionary!

The router is being used, with accessories, including the Woodrat Plungebar, as a precision driller rather than as a router. Using the guide bush for location in the correspondingly large holes in the jig, gets around the problem of repeated drilling in drill sized holes enlarging them.

Cheers

Basically what I'm asking is, why would one use substitutes if one has the correct tool for the job in hand, in this case a spiral down cut.

Bj, how does one fit Dremel tools into a 1/4", 8mm or 1/2" router?

Can't think of a better drill motor than a router,it always drills a true hole,always 90 deg.to the stock..
As you know they make left hand drill bits :) ( carb.bits the norm ,same as the spiral down cut router bits)
