Each division represents 0.01mm, giving you precise readings in the micron range. For cutting, to set your groove depth you measure your groove width. The ideal groove width is 50 microns (0.05mm), simply align the reticle over your grooves and count 5 divisions.\u003cbr\u003e\u003cbr\u003eSee the image for an example.\u003c\/p\u003e\n\u003cp class=\"p1\"\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"Spinner Town Blanks","offers":[{"title":"Default Title","offer_id":61362590613834,"sku":null,"price":10.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0810\/8628\/4106\/files\/WhatsAppImage2026-03-17at12.51.16_74be6e46-bee8-4591-ba15-9fbdfeedfe39.jpg?v=1773752277","url":"https:\/\/spinnertownblanks.com\/products\/reticle-ruler","provider":"Spinner Town Blanks","version":"1.0","type":"link"}
