The tool features a three-flute spiral geometry with a coarse profile (Z3) and upward chip extraction (positive), ensuring efficient removal of chips and a clean lower edge of the material. Coarse 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 edge. The ground shank with an accuracy class of 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 coarse Z3 (positive) design:\u003c\/strong\u003e The dedicated coarse profile breaks the chip into small fragments, reduces cutting resistance, efficiently evacuates chips upward, and guarantees a clean lower edge of the machined part.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eMonolithic carbide (VHM):\u003c\/strong\u003e The rigid monolithic construction reduces tool deflection under load and maintains high dimensional precision.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eExtended body with face milling:\u003c\/strong\u003e The non-cutting portion is face-milled to provide 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 grip 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 class G2.5:\u003c\/strong\u003e Balancing in accordance with ISO standards eliminates vibrations and reduces noise at high rotational speeds.\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eIntended use and application range:\u003c\/h3\u003e\u003cp\u003eThe tool is intended for chiselling and rough milling operations of lock cavities and for cutting and deep penetration in door wings on CNC machines.\u003c\/p\u003e\u003cp\u003eIt performs excellently when machining materials such as: softwood and hardwood, plywood, as well as raw particleboard and raw MDF.\u003c\/p\u003e","brand":"ITA TOOLS","offers":[{"title":"Default Title","offer_id":57444880154964,"sku":"SF30.18.095.150.18R","price":237.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1080\/4183\/0740\/files\/SF30.18.095.150.18R_195.18.095.150.18R-104.jpg?v=1793968262","url":"https:\/\/es.ita.tools\/en\/products\/fresa-helicoidal-desbaste-vhm-z3-d18-i95-l150-s18-rh-positivo","provider":"ITA TOOLS","version":"1.0","type":"link"}
