Hi guys..recently taken on a new job told and I have plenty of holes to drill.
They are to be drilled in 8mm steel with an end diameter of 12mm.
Now iv not drilled this thickness before so my question is how many times do I drill it to get to my required size..usually I pilot my holes with 4mm then straight to end result, but should I work my way up say 4mm 8mm 12mm?
