It is part of the Series 100 line, the heavy-duty comparators made for shop-floor use, and lets operators check a flat lapping finish against reference roughness values. A lightweight Microsurf equivalent (317) 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: Flat Lapping (criss-cross \/ parallel)\u003c\/li\u003e\n\u003cli\u003eNumber of patches: 4 + 4\u003c\/li\u003e\n\u003cli\u003eRa 0.025–0.2 µm \/ 1–8 µin\u003c\/li\u003e\n\u003cli\u003eRoughness grades N1–N4\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":67656279064689,"sku":"117","price":0.0,"currency_code":"AED","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0625\/3930\/0977\/files\/100-series-comparators_554aaea8-59d1-4891-89d1-98a990234230.jpg?v=1791811260","url":"https:\/\/www.generaltechshop.ae\/products\/rubert-117-series-100-roughness-comparator-flat-lapping-ra-0-025-0-2-m-n1-n4-4-patches","provider":"General Tech Services LLC","version":"1.0","type":"link"}
