{"product_id":"cnc-oma-finger-bit-green","title":"OMA HSA Green 8-Segment CNC Finger Bit — 20 × 40 mm","description":"\u003cp\u003eThe OMA HSA Green CNC Finger Bit is an Italian-made, wet-use diamond tool for routing sink cutouts and other programmed openings in granite, quartz, quartzite and marble. Its modified eight-double-segment design is built for aggressive material removal, even wear and consistent performance across mixed stone production.\u003c\/p\u003e\u003ch3\u003eVerified configuration\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e20 mm diameter × 40 mm cutting height\u003c\/li\u003e\n\u003cli\u003eEight double diamond segments\u003c\/li\u003e\n\u003cli\u003e1\/2-inch gas connection\u003c\/li\u003e\n\u003cli\u003eWet use only\u003c\/li\u003e\n\u003cli\u003eManufacturer\/supplier reference: XT-XTBIT3HS8\u003c\/li\u003e\n\u003cli\u003eLumax SKU: 10.12.0078\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eStarting parameters by material\u003c\/h3\u003e\u003cp\u003eThe matching supplier catalog lists 7,000–8,500 rpm. Use 12–16 inches per minute for quartzite and 15–24 inches per minute for quartz or granite as initial feed guidance. Tenax USA publishes a broader general operating window of 5,500–8,000 rpm and 14–25 inches per minute depending on the material. Use the material-specific values when they apply, then validate the cut on the actual slab and machine.\u003c\/p\u003e\u003ch3\u003eSetup and operation\u003c\/h3\u003e\u003cp\u003eConfirm the 1\/2-inch gas holder, spindle capacity, tool clearance, programmed path and continuous water delivery before machining. Check segment condition and runout before each job. During the first pass, monitor spindle load, sound, water flow and edge quality, reducing engagement if the machine or material shows stress. Final settings depend on stone composition, slab condition, depth of cut and CNC rigidity. Follow the current tool, machine and slab-manufacturer instructions. Setup and operation should be performed by trained personnel using required guarding and personal protective equipment.\u003c\/p\u003e","brand":"OMA","offers":[{"title":"Default Title","offer_id":52782602715367,"sku":"10.12.0078","price":169.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0777\/2038\/7815\/files\/10.12.0078-2.jpg?v=1791424362","url":"https:\/\/www.lumaxinnovations.com\/products\/cnc-oma-finger-bit-green","provider":"Lumax Innovations","version":"1.0","type":"link"}
