Pick a grade from the group you are cutting \u2014 a steel grade on a superalloy will fail quickly.<\/li>\n<li><strong>Feed, not depth of cut.<\/strong> The chipbreaker is defined by its feed window. Decide the feed first, then pick the geometry that covers it.<\/li>\n<li><strong>Nose radius versus finish.<\/strong> SNMM 250724 is stocked here at 2.4 mm. A larger radius gives better finish at the same feed and a stronger edge, but raises cutting force.<\/li>\n<\/ol>\n<p>Not sure whether SNMM 250724 is the right shape at all? The <a href=\"\/resources\/turning-insert-selection-guide\/\">turning insert selection guide<\/a> compares shapes by what the part profile allows.<\/p>\n<h2>Frequently asked questions about SNMM 250724<\/h2>\n<h3>What size insert is SNMM 250724?<\/h3><p>SNMM 250724 has an inscribed circle of 25.4 mm and a thickness of 7.94 mm. As a rule the depth of cut should stay under about two thirds of the inscribed circle.<\/p>\n<h3>What nose radius does SNMM 250724 have?<\/h3><p>The nose radius (the last two digits of the designation) is 2.4 mm on the variants listed here. Surface roughness scales roughly with fn\u00b2\/(32 \u00d7 RE), so at a fixed feed a larger radius halves Ra.<\/p>\n<h3>Which holder does SNMM 250724 fit?<\/h3><p>The holder designation must carry the same shape letter (S) and the same size digit. Send us your holder code and we will confirm the match before you order.<\/p>\n<h3>How many SNMM 250724 variants do you stock?<\/h3><p>16 variants from Achteck, listed below with grade, chipbreaker and the published cutting data where the manufacturer provides it.<\/p>\n<h3>What cutting speed should I run for SNMM 250724?<\/h3><p>For Steel, the published range across these variants is 45\u2013620 m\/min, with a typical window of 75\u2013510 m\/min. Heavy cuts sit at the bottom of that range, light finishing cuts at the top.<\/p>\n<h2>Related<\/h2><ul>\n<li>Same family: <a href=\"https:\/\/ychltools.com\/turning-inserts\/snmm\/snmm-250924\/\">SNMM 250924<\/a>, <a href=\"https:\/\/ychltools.com\/turning-inserts\/snmm\/snmm-190616\/\">SNMM 190616<\/a>, <a href=\"https:\/\/ychltools.com\/turning-inserts\/snmm\/snmm-190624\/\">SNMM 190624<\/a>, <a href=\"https:\/\/ychltools.com\/turning-inserts\/snmm\/snmm-190612\/\">SNMM 190612<\/a>, <a href=\"https:\/\/ychltools.com\/turning-inserts\/snmm\/snmm-120408\/\">SNMM 120408<\/a>, <a href=\"https:\/\/ychltools.com\/turning-inserts\/snmm\/snmm-120412\/\">SNMM 120412<\/a>, <a href=\"https:\/\/ychltools.com\/turning-inserts\/snmm\/snmm-150612\/\">SNMM 150612<\/a>, <a href=\"https:\/\/ychltools.com\/turning-inserts\/snmm\/snmm-150616\/\">SNMM 150616<\/a><\/li>\n<li><a href=\"https:\/\/ychltools.com\/turning-inserts\/snmm\/\">All SNMM<\/a><\/li>\n<li><a href=\"https:\/\/ychltools.com\/turning-inserts\/snmm\/snmm-250724\/achteck\/\">Achteck SNMM 250724<\/a> (16 variants)<\/li>\n<li><a href=\"\/resources\/iso-insert-code-decoder\/\">Decode the SNMM 250724 designation<\/a><\/li>\n<li><a href=\"\/resources\/cutting-parameters-calculator\/\">Cutting speed to rpm calculator<\/a><\/li>\n<li><a href=\"\/resources\/turning-insert-selection-guide\/\">Turning insert selection guide<\/a><\/li>\n<\/ul>"},"class_list":["post-8215","page","type-page","status-publish","hentry"],"_links":{"self":[{"href":"https:\/\/ychltools.com\/zh\/wp-json\/wp\/v2\/pages\/8215","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/ychltools.com\/zh\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/ychltools.com\/zh\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/ychltools.com\/zh\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/ychltools.com\/zh\/wp-json\/wp\/v2\/comments?post=8215"}],"version-history":[{"count":1,"href":"https:\/\/ychltools.com\/zh\/wp-json\/wp\/v2\/pages\/8215\/revisions"}],"predecessor-version":[{"id":10031,"href":"https:\/\/ychltools.com\/zh\/wp-json\/wp\/v2\/pages\/8215\/revisions\/10031"}],"up":[{"embeddable":true,"href":"https:\/\/ychltools.com\/zh\/wp-json\/wp\/v2\/pages\/7899"}],"wp:attachment":[{"href":"https:\/\/ychltools.com\/zh\/wp-json\/wp\/v2\/media?parent=8215"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
