Drills are intended for axial loading, mills need to be able to handle both axial and radial loading. A drill will probably have a single thrust bearing at the bottom of the spindle and a fairly small diameter spindle with the chuck held on a Jacobs taper or in an internal Morse taper. A mill will probably have a pair of opposed bearings at the bottom that are designed for both thrust and side load and the spindle will be larger in diameter with a through hole for the drawbar that holds collets in place for the tool.
Even if you somehow replaced the bearings on a drill and figured out how to hold a tool more securely than a taper you would probably find the small diameter spindle too flexible.
An open mind is a virtue...so long as all the common sense has not leaked out.
old shop i worked at had a big radial drill head on a fixed column and arm over a large table that they added a cnc control to for positioning quickly and accurately. they decided to make a mill out of it for milling pockets in a large alum extrusion job. modded a taper holder and fixed it in place with a wedge, could hold 1/2 & 3/4 endmills. it would mill, but squealed like a pig, no shreeked like a banshee more like it, and generated chips that were tiny razor sharp needles that went into your skin and made your hands very sore, no matter how you tried to avoid them. for years i tried to convince them just to mount a bridgeport type head instead, no dice. posters here are right, get a milling head, even if its low end and cheap.
One of our members tried this... it was an interesting exercise in collaborative thinking... but ultimately futile.... a cheap mill-drill would have been about the same cost!Originally Posted by Drakkn

A drill press is a drill press. A drill press modified to perform milling is still a drill press, not a mill.

it drills in the right places now, better than i can do by eye anyway.
had resonable success with steel and aluminium making motor mounting plates etc. (what i did it for)
see video on utube.

so much to learn, so much to pass on.
No, no, no. Not safe at all! don't do it unless wearing body armour and a motorcycle helmet.
In fact you know them full plate armour the knights used to wear? oh and a full length shield.
You will have an HSS end mill (or bits of it) flying at you.
Drill presses are not designed for side loads.
I love deadlines- I like the whooshing sound they make as they fly by.
lol!
it was converted mainly for accurate drilling but ive been v carving etc on it too. i know its not a mill or a router etc its a drill press but a fun project none the less!
and yes ive had the morse taper drop out!
see http://www.mercuryleisure.co.uk/auto...-machines.html
for some of the other bits its made this week.
i would love a real mill but with all the other equipment here i just dont have room for one!
so much to learn, so much to pass on.
I "played" at it 20 years ago.....Gotta love the spinning top
Unless the cutter is 75mm+ it can't get to the heart....so it's fairly safe.......It'd have to be lucky to get the brain lol

Lots of other soft spots it could get to though!
Im a firm beleiver in "if something bad can happen, it will happen".
It'll fall off or break and hit the grinder to the left at the perfect angle to deflect 33 degrees down towards your nads cos the devil always watches engineers- he dun like thiings getting made perfect
In fact...just don't do it hehe.

the chinese drill used is also sold as a chinese mill. it has huge bearings for side loads so that bit doesnt worry me. the annoying thing is it doesnt have a hollow shaft to make up a draw bar for the taper. damned chinese dont they realise people will do other things with their machines!
i normally walk away and use the other machines and just leave this to do its job in the corner. its making gearbox mounting plates at the moment, for my plasma cutter build in steel( as long as the taper hasnt dropped out) lol
my hospital accident unit is only 200yds away :-)
its saving me a week wait and a lot of money at the local engineers shop.
so much to learn, so much to pass on.
