VHM Spiral End Mill Compression Finishing Z#number_of_edges_z from the SL01 series – ideal edge quality without tears

Index: SL01.06.022.060.06TR

Industrial spiral end mill made of solid carbide (VHM) from the SL01 series with compression geometry. The tool is equipped with opposing helical cutting edge flutes, which 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 edges, as well as nesting cutting on CNC machining centres. The compression construction eliminates the risk of chipping and tears on both sides of the material being processed. The ground shank in class H6 reduces radial runout, ensuring smooth machining and long spindle life.

Structural advantages and technical properties:

• Compression geometry (Positive-Negative): The combination of right and left hand flutes guarantees a smooth, clean edge without tears on both the upper and lower surfaces of the board.
• Finishing cutting edge geometry: Precisely ground cutting edges ensure high surface quality without the need for additional finishing operations.
• Solid carbide (VHM): The rigid monolithic construction reduces tool deflections under load and allows for dimensional accuracy.
• Low shank roughness (Ra ≤ 0.3 µm): The ground shank surface prevents slipping in the tool holder and protects the spindle cone from wear.
• Dynamic balance in class G2.5: The balancing in accordance with ISO standards eliminates vibrations at high rotational speeds.
• Specialist protective coating TiSiN: PVD coating with a copper colour, 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, which significantly extends the tool life and reduces the frequency of tool changes.  

Intended use and range of application:

The tool is designed for cutting operations, nesting cutting, and edging and trimming on CNC machines.

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