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

Index: SN01.95.222.762.95R

Industrial spiral cutter made from solid carbide (VHM) from the SN01 series with a compression geometry. The tool features opposing helical cutting edges, which simultaneously push the chips down from the upper edge and up from the lower edge, pressing the laminate against the core of the plate. Designed for finishing, cutting, edging, and trimming operations 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 with an accuracy class of H6 minimises radial runout, ensuring smooth machining and long spindle life.

Design 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 plate.
• Finishing blade geometry: Precisely sharpened cutting edges ensure high surface quality without the need for additional finishing.
• Solid carbide (VHM): The rigid monolithic structure reduces tool deflection under load and helps maintain dimensional precision.
• Low shank 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 application range:

The tool is intended for cutting operations, nesting technology cutting as well as edging and trimming on CNC machines.

It performs excellently in 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.
