The tool features a three-flute spiral geometry with a roughing profile (Z3) and upward chip evacuation (positive), which ensures efficient chip removal and a clean lower edge of the material. The roughing tooth design with a chip breaker reduces cutting resistance and decreases spindle load. The extended body with a taper allows for deep penetration into the material without the risk of rubbing or burning the edges. The ground shank in accuracy class H6 eliminates radial runout, protecting the drive system and ensuring process stability.\u003c\/p\u003e\u003ch3\u003eDesign advantages and technical properties:\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e\u003cstrong\u003eThree-flute roughing design Z3 (positive):\u003c\/strong\u003e Dedicated roughing profile breaks chips into small pieces, reduces cutting resistance, efficiently evacuates chips upwards and guarantees a clean lower edge of the machined element.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eSolid carbide (VHM):\u003c\/strong\u003e The rigid monolithic structure reduces tool deflection under load and allows for high dimensional precision.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eExtended body with a recess:\u003c\/strong\u003e The recessed non-cutting part provides technological clearance, allowing for deep chiselling of lock cavities without the risk of the body rubbing against the material walls.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eLow shank roughness (Ra ≤ 0.3 µm):\u003c\/strong\u003e The ground surface of the shank prevents slipping in the tool holder and protects the spindle taper from wear.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eDynamic balancing in class G2.5:\u003c\/strong\u003e Balancing according to ISO standards eliminates vibrations and reduces noise at high rotational speeds.\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003ePurpose and range of application:\u003c\/h3\u003e\u003cp\u003eThe tool is designed for chiselling and rough milling of cavities for door locks and cutting and deep recessing in door leaves on CNC machines.\u003c\/p\u003e\u003cp\u003eIt excels in machining materials such as: softwood and hardwood, plywood, and raw particle board and raw MDF.\u003c\/p\u003e","brand":"ITA TOOLS","offers":[{"title":"Default Title","offer_id":57444956799316,"sku":"SF30.16.120.170.16XR","price":216.5,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1080\/4183\/0740\/files\/SF30.16.120.170.16XR_195.16.120.170.16XTR-111.jpg?v=1791282954","url":"https:\/\/es.ita.tools\/en\/products\/fresa-helicoidal-desbaste-vhm-z3-d16-i120-l170-s16-rh-positivo-nadia","provider":"ITA TOOLS","version":"1.0","type":"link"}
