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.

Introduction to Machining: Milling Machine

•In vertical mills, milling cutters with solid shafts are usually used. Milling cutters with keyed holes are predominantly for use in horizontal mills. End mills are designed for cutting slots, keyways and pockets. Two fluted end mills can be used to plunge into work like a drill. End mills with more than two flutes should not be plunged into the
