It provides 8 (4 + 4) reference patches spanning reaming patches covering Ra 0.4–3.2 µm (16–125 µin, N5–N8) and drilling patches covering Ra 1.6–12.5 µm (63–500 µin, N7–N10). Machinists and inspectors use it to compare a reaming \u0026amp; drilling finish directly against known roughness values. A lightweight Microsurf equivalent (322) 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: Reaming and Drilling\u003c\/li\u003e\n\u003cli\u003eNumber of patches: 8 (4 + 4)\u003c\/li\u003e\n\u003cli\u003eReaming: Ra 0.4–3.2 µm \/ 16–125 µin, N5–N8\u003c\/li\u003e\n\u003cli\u003eDrilling: Ra 1.6–12.5 µm \/ 63–500 µin, N7–N10\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":67656281489521,"sku":"122","price":0.0,"currency_code":"AED","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0625\/3930\/0977\/files\/100-series-comparators_6e3cc915-1996-432a-9908-357a1a9fb463.jpg?v=1791811369","url":"https:\/\/www.generaltechkuwait.com\/products\/rubert-122-series-100-roughness-comparator-reaming-and-drilling-ream-ra-0-4-3-2-m-drill-1-6-12-5-m","provider":"General Tech Services LLC","version":"1.0","type":"link"}
