VHM Compression Finishing Spiral Cutter Z#liczba_ostrzy_z from the SM01 series – ideal edge quality without chipping

Index: SM01.08.018.070.08TR

Industrial spiral cutter made from solid carbide (VHM) from the SM01 series with compression geometry. The tool is equipped with opposite screw-like lines of blades that simultaneously push chips down from the top edge and up from the bottom edge, pressing the laminate against the core of the panel. Designed for finishing machining, cutting, jointing and edge levelling 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 machined material. The ground shank in accuracy class H6 reduces radial run-out, ensuring smooth machining and long spindle life.

Design advantages and technical properties:

• Compression geometry (Positive-Negative): The combination of right and left-handed blades ensures a smooth, clean edge without chipping on both the top and bottom surfaces of the panel.
• Finishing blade geometry: Precisely ground cutting edges ensure high surface quality without the need for additional finishing machining.
• Solid carbide (VHM): The rigid monolithic design reduces tool deflection under load and allows for dimensional precision.
• Low roughness of the shank (Ra ≤ 0.3 µm): The ground shank surface prevents slipping in the tool holder and protects the spindle cone from wear.
• Dynamic balancing class G2.5: Balancing in accordance with ISO standards eliminates vibrations at high rotational speeds.
• Special protective TiSiN coating: PVD coating with a copper hue, thickness of 1–4 µm and high micro-hardness of 3570 HV (HV 0.05). It exhibits excellent resistance to abrasive and thermal wear during high cutting temperature operations, significantly extending the blade life and reducing tool change frequency.  

Intended use and scope of application:

The tool is intended for cutting operations, nesting cutting technology, as well as jointing and edge levelling 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.
