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

Index: SN01.12.025.083.12R

Industrial spiral cutter made from solid sintered carbide (VHM) from the SN01 series with a compression geometry. The tool is equipped with reverse helical cutting edges, 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 cutting technology on CNC machining centres. The compression design eliminates the risk of chipping and tearing on both sides of the workpiece. The ground shank in accuracy class H6 eliminates radial runout, ensuring smooth machining and long spindle life.

Structural advantages and technical properties:

• Compression geometry (Positive-Negative): The combination of right and left-handed cutting edges guarantees a smooth, clean edge without chipping on both the upper and lower surfaces of the board.
• Finishing edge geometry: Precisely ground cutting edges ensure high surface quality without the need for additional finishing operations.
• Solid sintered carbide (VHM): The rigid monolithic structure 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 in class G2.5: Balancing according to ISO standards eliminates vibrations at high rotational speeds.

Intended use and scope of application:

The tool is designed for cutting, nesting cutting operations, jointing and edging on CNC machines.

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