Spiral router bit Finishing VHM Z3+3 D20 I100 L165 S20 RH pos./neg. TiSiN

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

Index: SN01.20.100.165.20TR

Industrial spiral cutter made of solid carbide (VHM) from the SN01 series with compression geometry. The tool is equipped with opposite screw lines of the blades, which simultaneously push the chip down from the upper edge and up from the lower edge, pressing the laminate against the core of the board. Designed for finishing operations, cutting, jointing and edging, 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 machined material. The ground shank in the accuracy class H6 reduces radial runout, ensuring smooth machining and long spindle life.

Structural advantages and technical properties:

• Compression geometry (Positive-Negative): The combination of left and right twist blades guarantees a smooth, clean edge without chipping 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.
• Solid carbide (VHM): The rigid monolithic construction reduces tool deflection under load and helps maintain dimensional accuracy.
• Low shank roughness (Ra ≤ 0.3 µm): The ground shank surface prevents slipping in the tool holder and protects the spindle cone from wear.
• Dynamic balancing in class G2.5: Balancing in accordance with ISO standards eliminates vibration at high rotational speeds.
• Specialist protective TiSiN coating: Copper-coloured PVD coating, 1-4 µm thick, with a high microhardness of 3570 HV (HV 0.05). It shows excellent resistance to abrasive and thermal wear when working at high cutting temperatures, significantly extending blade life and reducing tool change frequency.  

Purpose and area of application:

The tool is designed for cutting, nesting technology cutting, as well as jointing and edging on CNC machines.

It performs excellently in the machining of materials such as: solid soft and hard wood, raw and laminated MDF board, raw and laminated chipboard, as well as raw and veneered plywood.
