The tool features a three-flute spiral geometry with a roughing profile (Z3) and a positive chip evacuation upwards, ensuring efficient chip removal and a clean lower edge of the material. The roughing teeth with a chip breaker reduce cutting resistance and lower spindle load. The extended body with taper allows for deep penetration into the material without the risk of rubbing or burning the edges. The ground shank in accuracy class H6 minimises 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 The dedicated roughing profile breaks chips into small pieces, lowers cutting resistance, effectively 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 construction reduces tool deflection under load and maintains high dimensional precision.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eExtended body with counter-bore:\u003c\/strong\u003e The counter-bored non-cutting part provides technological clearance, allowing for deep chiselling of lock sockets 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 cone 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\u003eIntended use and scope of application:\u003c\/h3\u003e\u003cp\u003eThe tool is intended for chiselling and rough milling of sockets for door locks, as well as cutting and deep sinking in door panels on CNC machines.\u003c\/p\u003e\u003cp\u003eIt performs excellently when machining materials such as: soft and hardwood, plywood, as well as raw particle board and raw MDF.\u003c\/p\u003e","brand":"ITA TOOLS","offers":[{"title":"Default Title","offer_id":57444946870612,"sku":"SF30.16.120.170.16R","price":200.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1080\/4183\/0740\/files\/SF30.16.120.170.16R_SF30.16.120.170.16R-104.jpg?v=1793968260","url":"https:\/\/es.ita.tools\/en\/products\/fresa-helicoidal-desbaste-vhm-z3-d16-i120-l170-s16-rh-positivo","provider":"ITA TOOLS","version":"1.0","type":"link"}
