\u25c6<\/span>22ER\/22IRM Insert Overview<\/h2>\n
<\/div>\n<\/div>\n

These 22-size carbide thread-turning inserts<\/strong> are presented for external (22ER) and internal (22IRM) 60\u00b0 metric threading of stainless-steel components. Select a pitch-specific 3.5 ISO full-profile insert when the drawing calls for a 3.5 mm metric thread and a formed crest. An N60 partial-profile insert is a separate geometry that may cover a stated range of metric pitches; confirm the actual insert designation and range before ordering.<\/p>\n

For 304, 316 or other stainless grades, review the insert’s verified carbide grade, coating, cutting-edge geometry and holder with the workpiece and thread drawing. Reliable threading also depends on suitable infeed passes, chip evacuation, correct helix clearance and finished-thread gauging. The exact dimensions and cutting data must be confirmed for the selected HY item.<\/p>\n<\/section>\n

\u25c6<\/span>Stainless-Steel Threading Considerations<\/h2>\n
<\/div>\n<\/div>\n
\n

Profile and crest:<\/strong> a confirmed full-profile insert cuts the specified crest; a partial-profile insert requires the starting diameter to be prepared correctly.<\/p>\n

Chip control:<\/strong> select a stainless-suitable edge and coating by grade, then check chip flow and coolant delivery during the trial cut.<\/p>\n

Internal-thread clearance:<\/strong> check minimum bore, overhang, chip space, holder orientation and shim or anvil tilt for a 22IRM setup.<\/p>\n

Thread verification:<\/strong> use the drawing’s thread class and an appropriate gauge; the profile name alone does not specify finished-thread tolerance.<\/p>\n<\/div>\n<\/section>\n

<\/div>\n<\/div>\n

Send the metric thread designation and tolerance, 3.5 ISO or N60 profile choice, external\/internal location, right\/left hand, holder model, stainless-steel grade, diameter, thread length and quantity. Request a drawing and material-specific cutting recommendation for the selected configuration.<\/p>\n

See our CNC Insert Selection Guide<\/a> or request a specification check<\/a>.<\/p>\n<\/section>\n

22ER and 22IRM 3.5 ISO carbide threading inserts are designed for external and internal thread machining in stainless steel. Precision-ground thread profiles support consistent pitch accuracy and surface quality, while suitable coated grades improve edge durability and chip control. The range supports repeat production and replacement-code matching for distributors.<\/p>\n
