Drilling holes - Cheapest & quickest way

I wouldn't know about gym equipment, I get all my exercise from hard work.

That's what I was thinking that's why I mentioned the burr would leave

really is going to be jig and drill it, or shop it out

all comes down to just how meany for how long, might just need a drill and a monkey / drilling bitch.

I think you are right Danny.
Ive pointed him in the direction of a big 3 phase Meddings pillar drill with a 100rpm lowest setting which will do the job. I think he might be in for a surprise of just how much time he will be spending (not personally mind you!) drilling holes, despite my warning.

Just on the time issue. Say a 15mm hole in 50x50x3mm box, rough time for each hole?

Realistically with jigging, swarf removal, sharpening off drill, cleanup etc. about 20 seconds a hole, 30 if you go straight through to drill both sides. Swarf is the biggest pain, it winds around every thing and is a ****** to clear up.

Plus another 10 for deburring around the top of the hole. Either a vargus tool or countersink on a handle.
