VHM compression finishing spiral cutter Z#liczba_ostrzy_z from the SM01 series – perfect edge quality without tear-outs

Index: SM01.08.022.070.08TR

Industrial spiral cutter made of solid carbide (VHM) from the SM01 series with compression geometry. The tool is equipped with opposing helix cutting edges that push chips down from the top edge and up from the bottom edge, pressing the laminate against the core of the board. Designed for finishing operations, cutting, edge banding, and trimming edges as well as nesting cutting on CNC machining centres. The compression design eliminates the risk of chipping and tear-outs on both sides of the workpiece. The ground shank in class H6 compensates for radial runout, ensuring smooth machining and a long spindle lifespan.

Structural advantages and technical properties:

• Compression geometry (Positive-Negative): The combination of right-hand and left-hand twist cutting edges guarantees a smooth, clean edge without tear-outs on both the top and bottom surfaces of the board.
• Finishing cutting edge geometry: Precisely ground cutting edges ensure a high surface quality without the need for additional finishing operations.
• Solid carbide (VHM): The rigid monolithic structure reduces tool deflection under load and maintains dimensional accuracy.
• 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.
• Specialist protective coating TiSiN: PVD coating with a copper hue, thickness of 1–4 µm and high microhardness of 3570 HV (HV 0.05). It exhibits excellent resistance to abrasive and thermal wear when working at high cutting temperatures, significantly extending cutting tool life and reducing tool change frequency.  

Intended use and application range:

The tool is intended for cutting, nesting, edge banding, and trimming operations on CNC machines.

It performs excellently in the machining of materials such as: soft and hardwood, raw and laminated MDF boards, raw and laminated chipboards, as well as raw and veneered plywood.
