Its 8 patches cover Ra 0.4–50.0 µm (16–2000 µin), roughness grades N5–N12. Series 100 plates are the heavy-duty design intended for workshop use, so the 121 can be kept beside the machine for comparing parts with known reference finishes. A lightweight Microsurf equivalent (321) is offered for office and design use.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eKey features\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eMachining method: End Milling\u003c\/li\u003e\n\u003cli\u003eNumber of patches: 8\u003c\/li\u003e\n\u003cli\u003eRa 0.4–50.0 µm \/ 16–2000 µin\u003c\/li\u003e\n\u003cli\u003eRoughness grades N5–N12\u003c\/li\u003e\n\u003cli\u003eHeavy-duty Series 100 construction for workshop use\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Rubert","offers":[{"title":"Default Title","offer_id":67656280146033,"sku":"121","price":0.0,"currency_code":"AED","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0625\/3930\/0977\/files\/100-series-comparators_d8420151-e56e-4948-a2ed-e1a6d09415b1.jpg?v=1791811347","url":"https:\/\/www.generaltechkuwait.com\/products\/rubert-121-series-100-roughness-comparator-end-milling-ra-0-4-50-0-m-n5-n12-8-patches","provider":"General Tech Services LLC","version":"1.0","type":"link"}
