I am a new member. My name is John. I have a CNC machine and would like to see if anyone knows of a chuck to use a standard drill bit in a router?

John, I just re-read your post and would have to say NOT to use a standard drill bit in a router. They are not designed for high speeds 20,000 - 25,000RPM. and probably not designed for sideways cutting, but drilling down.

second to jw2170's post. Consider a drill press for that operation.

Hi John

Many will say it's not safe but I use one in the router from time to time, I took one out of bat.type drill and put in a threaded stub type bolt, 3/8-24 thread and it works just fine..no problems at all..most drill chucks are made in the high end way... I use a Adapter Bushings from MLCS
#277 1/2" 3/8" $4.00
MLCS Woodworking Adaptor Bushings and Ball Bearing Guides


By the way you don't need to spin a drill bit or a drill chuck at 20,000 rpm's for it to do the work.
Just like the bit in the link below

Default elairecorp.com router collets

Hi John,
You can buy collets for several router types that will take drill bits at:
Elaire Corporation -Router Collets
A number of safety-conscious posters in this forum do not agree with my use of a router for drilling, but I have used my porter-cable router in a table setting to drill pen blanks with 7, 8, and 10mm holes using the collet set from Elairecorp.com .
The slower the router speed the better.
Note: The colleted drills are for plunge routing. They are not designed for any sideways cutting and that should be a hazard to avoid.
Mark

Hi John,

Welcome to The Router Forums.

I kind of sense the reason you would like to equip your CNC router with a '3 jaw chuck' is to make it easy to drill precisely spaced holes, of varying sizes, using a CNC 'program' that automates the process.

Though many here might consider this technique to be reckless, if I needed to drill a lot of holes on a specific pattern and had a CNC platform, I would be doing what you are asking about.

That being said, I would be extra careful in a couple areas. Cutter care and inspection would be at their highest. Extra thick safety glasses on this one...I suspect that doing this a lot would result in some broken bits. Odds are the CNC isn't smart enough to know when a cutter fails in that way, so being prepared to shut it down at any point during the sequence is advised.

Awareness of grain patterns/knots in the workpiece that could cause a cutter to bend during the 'plunge cut' (if the material is wood). I would use as short of drills as available to minimize the 'bending' caused when it's easier for a cutting edge to 'walk away' during a plunge, than it is to cut.

If you have a lot of this kind of drilling that needs to be done, it might be worthwhile to find away to slow the rpm down.

The approach Bob mentioned is the simplest that I am aware of. A lot of chucks on hand drills just have a 'threaded' hole that they attach to the rest of the drill with. I didn't know that MLCS sold adapters like that, so thanks to Bob for speaking up!

I kind of want to rig up a 3 jaw friction tightened chuck on one of my Yankee push drills!
