When drilling holes smaller than 1xDC hole depths it is possible to increase the revolution speed by 20%. 2) 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. 3) For counter boring of a sloped face a carbide end mill is recommended. 4) When machining austenitic stainless steels (JIS SUS304 SUS316) set the revolution at 40%-70% and the feed rate 40%-60%. 5) Please use a collet type drill chuck or a milling chuck. 6) Please reduce the revolution and feed rate depending on the drilling situation when the installation of workpiece or machine lacks rigidity. 7) 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. N161 DRILLING
