The front construction facilitates axial entry into the material in the Z-axis, reducing cutting resistance and eliminating the risk of structure damage upon entry. The multi-edge cutting system crushes the material, preventing delamination of composites and extraction of glass and carbon fibres. The neutral cutting direction does not generate axial forces (either pressing or lifting), ensuring a high standard of edge finish on both sides of the plate. Designed for efficient cutting, grooving, and welding on CNC machining centres. The ground shank in class H6 protects the spindle from vibrations and prevents radial runout.\u003c\/p\u003e\u003ch3\u003eDesign advantages and technical properties:\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e\u003cstrong\u003eRosette front geometry (CNR):\u003c\/strong\u003e The dedicated front configuration reduces resistance during axial plunging, allowing stable entry into the material.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eRough multi-edge system:\u003c\/strong\u003e Dense tooth arrangement finely crushes chips, preventing layer separation and edge fraying.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eNeutral chip ejection to the sides:\u003c\/strong\u003e The absence of pressure and lifting on the workpiece guarantees stable cutting and a clean profile on both sides.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eMonolithic carbide (VHM):\u003c\/strong\u003e High hardness and wear resistance ensure longer life when machining abrasive materials.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eLow shank roughness (Ra ≤ 0.3 µm):\u003c\/strong\u003e Precisely ground shank prevents slipping in the holder and protects the spindle cone from wear.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eDynamic balancing G2.5:\u003c\/strong\u003e Compliance with ISO standards enables safe and vibration-free operation at very high speeds.\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eIntended use and application range:\u003c\/h3\u003e\u003cp\u003eThe tool is intended for rough cutting operations, entering the material in the Z-axis, cutting and welding in composites and plywood on CNC machines.\u003c\/p\u003e\u003cp\u003eUsed in machining materials such as fibre-reinforced plastics (CFRP), glass fibre (GFRP), CORIAN® composite boards, HPL laminates, and plywood.\u003c\/p\u003e","brand":"ITA TOOLS","offers":[{"title":"Default Title","offer_id":57445051040084,"sku":"CNR.12.030.090.12R","price":85.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1080\/4183\/0740\/files\/CNR.12.030.090.12R_CNR.12.030.090.12R-109_90b62857-6b72-4bbb-9deb-01b95678ff8b.jpg?v=1793968633","url":"https:\/\/es.ita.tools\/en\/products\/fresa-para-composites-desbaste-d12-i30-l90-s12-rh","provider":"ITA TOOLS","version":"1.0","type":"link"}
