When drilling holes smaller than 1xDC hole depths, it is possible to increase the revolution speed by 20%. Drilling without a pilot hole is recommended. If there is a pilot hole, chips are not broken. Use a pick feed when chip breaking is necessary. For counter boring of a sloped face, a carbide end mill is recommended. When machining austenitic stainless steels(JIS SUS304.SUS316),set the revolution at 40%-70% and the feed rate 40%-60%. Please use a collet type drill chuck or a milling chuck. Please reduce the revolution and feed rate depending on the drilling situation when the installation of workpiece or machine lacks rigidity. Use sufficient cutting fluid. The above-mentioned cutting condition is standard when using water-soluble cutting fluid. Please reduce the revolution when using non-water-soluble cutting fluid. Mitsubishi Materials 1817 DRILLING
