VHM spiral compression finishing cutter Z#liczba_ostrzy_z from the SL01 series – ideal edge quality without chipping

Index: SL01.05.022.070.05TR

Industrial spiral cutter made of sintered carbide (VHM) from the SL01 series with compression geometry. The tool is equipped with opposing spiral blade lines that simultaneously push the chips 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 edge trimming 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 processed. The ground shank in accuracy class H6 eliminates radial runout, ensuring smooth processing and long spindle lifespan.

Design advantages and technical properties:

• Compression geometry (Positive-Negative): The combination of right-hand and left-hand twist blades guarantees a smooth, clean edge without tearing on both the upper and lower surfaces of the board.
• Finishing blade geometry: Precisely sharpened cutting edges ensure high surface quality without the need for additional finishing machining.
• Sintered carbide (VHM) monolith: The rigid monolithic construction reduces the tool's deflection under load and preserves dimensional accuracy.
• Low shank roughness (Ra ≤ 0.3 µm): The ground shank surface prevents slipping in the tool holder and protects the spindle taper from wear.
• Dynamic balancing in class G2.5: Balancing in accordance with ISO standards eliminates vibrations at high rotational speeds.
• Special protective coating TiSiN: Copper-coloured PVD coating, 1–4 µm thick, with high micro-hardness of 3570 HV (HV 0.05). It demonstrates excellent resistance to abrasive and thermal wear when machining at high cutting temperatures, which significantly extends the tool's lifespan and reduces the frequency of tool changes.  

Intended use and scope of application:

The tool is designed for cutting operations, nesting technology cutting, as well as jointing and edge trimming 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.
