VHM spiral end mill compression finishing Z#number_of_edges_z from the SM01 series – ideal edge quality without chipping

Index: SM01.12.018.070.12TR

Industrial spiral end mill made from solid carbide (VHM) from the SM01 series with compression geometry. The tool is equipped with opposing helical flutes 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, cutting, edging, and trimming, as well as nest 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 with an accuracy class of H6 mitigates radial runout, ensuring smooth machining and long spindle life.

Construction advantages and technical properties:

• Compression geometry (Positive-Negative): The combination of right-hand and left-hand cutting edges ensures a smooth, clean edge without chipping on both the upper and lower surfaces of the board.
• Finishing cutting edge geometry: Precisely ground cutting edges provide high surface quality without the need for additional finishing.
• Solid carbide (VHM): The rigid monolithic construction reduces tool deflection under load and maintains 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 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 microhardness of 3570 HV (HV 0.05). It exhibits excellent resistance to abrasive and thermal wear when working at high cutting temperatures, significantly extending the tool life and reducing tool change frequency.  

Intended use and application range:

The tool is designed for cutting, nest cutting, as well as edging and trimming on CNC machines.

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