Compression finishing VHM spiral cutter Z#liczba_ostrzy_z from the SN01 series – ideal edge quality without chips

Index: SN01.12.025.083.12TR

Industrial spiral cutter made from solid sintered carbide (VHM) from the SN01 series with compression geometry. The tool is equipped with opposing screw lines of the blades that simultaneously push chips down from the upper edge and up from the lower edge, pressing the laminate against the core of the board. Designed for finishing machining, cutting, jointing and edge leveling, as well as nesting technology cutting on CNC machining centres. The compression design eliminates the risk of chipping and tearing on both sides of the material being machined. The ground shank in class accuracy H6 eliminates radial runout, ensuring smooth machining and long spindle life.

Design advantages and technical properties:

• Compression geometry (Positive-Negative): The combination of right and left twist blades guarantees a smooth, clean edge without chips on both the upper and lower surfaces of the board.
• Finishing blade geometry: Precisely ground cutting edges ensure high surface quality without the need for additional finishing machining.
• Monolithic sintered carbide (VHM): The rigid monolithic construction reduces tool deflection under load and maintains dimensional precision.
• Low grip roughness (Ra ≤ 0.3 µm): The ground surface of the shank prevents slipping in the tool holder and protects the spindle taper from wear.
• Dynamic balancing class G2.5: Balancing in accordance with ISO standards eliminates vibrations at high rotational speeds.
• Specialist protective coating TiSiN : PVD coating with a copper colour, thickness of 1–4 µm and high microhardness of 3570 HV (HV 0.05). Exhibits excellent resistance to abrasive and thermal wear when operating at high cutting temperatures, significantly extending blade life and reducing tool change frequency.  

Purpose and scope of application:

The tool is designed for cutting operations, nesting cutting, as well as jointing and edge leveling on CNC machines.

It is particularly effective for machining materials such as: solid soft and hard wood, raw and laminated MDF board, raw and laminated chipboard, as well as raw and veneered plywood.
