Novice question - why would you want a "special diameter" end mill?

Best Regards

:) Its for some pressed fittings I need to use - the hole size is very specific and while I could probably get away with 5.5mm the closer I get to

I didn't think you could cut holes with end mills?

Steve

I have to make 5.4mm holes in 3mm plate to about 2mm in depth.

The fastening supplier (these are pressed into the hole/slot) recommended an end mill.

I was going to try and see if I can do this on an low-end industrial drill press as its just straight downward pressure but wasn't sure. Any thoughts?

Thanks,

oh ya - and its just 3mm aluminum - nothing too hard :)

You'll need to make sure that you get a centre-cutting end mill.

The two-flute versions of which are know as slot-drills. Americans call them two-flute centre-cutting end mills - catchy, eh?

One of the trade catalogue that I have sent here, did list endmills in .1mm increments in one of their flyers. I forget who it was now. possibly WNT.

Unless your plate is clamped for each hole you can forget trying to work to

It's just like trying to start a drill on a shiny surface with no centre punch mark

How about using a " butchered " 5.4 mm stub drill

I was thinking about this today and something twigged. - If I need a hole say 2mm deep could I use a drill bit to start the hole (if I can find one shallow enough only to go 2mm) and then use the end mill to 'square' the mitre off?

That way I could use the drill press and the end mill would have a guide.

Would that work?

I would clamp the job to the drill table and use a slot dill reground to

I actually ran some tests last night and the drill bits I have are almost exactly 2mm deep (from point to outer dia) so I can use that to set the hole - put the slot drill on after and 'flatten' it out. I think I'll try that as I have quite a few holes to do and that would make it go quick :)

Thanks for all the help!
