Introduction to the Mill

End mills are designed to cut square slots. They will produce a slot to within two onethouhs of an inch in one pass. If greater accuracy is required, use an end mill a little smaller than the desired slot. Measure the slot produced and open it to the desired dimension with a second pass. The following clip shows and end mill cutting a slot.
