Spiral CNC finishing end mill Z#number_of_blades_z from the SL01 series – ideal edge quality without chipping

Index: SL01.04.021.060.04TR

Industrial spiral end mill made of solid sintered carbide (VHM) from the SL01 series with compression geometry. The tool is equipped with counter-rotating helical cutting edges that simultaneously push the chips down from the top edge and up from the bottom, pressing the laminate against the core of the board. Designed for finishing machining, cutting, edge banding, and nesting technology cutting 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 the H6 accuracy class eliminates radial runout, ensuring smooth machining and a long spindle life.

Construction advantages and technical properties:

• Compression geometry (Positive-Negative): The combination of right-hand and left-hand cutting edges guarantees a smooth, clean edge without chipping on both the upper and lower surfaces of the board.
• Finishing cutting edge geometry: Precisely sharpened cutting edges ensure high surface quality without the need for additional finishing processing.
• Solid sintered carbide (VHM): The rigid monolithic construction reduces tool deflection under load and maintains dimensional precision.
• 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 to class G2.5: Balancing in accordance with ISO standards eliminates vibrations at high rotational speeds.
• Special protective coating TiSiN: A 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 blade life and reducing the frequency of tool replacement.  

Intended use and scope:

The tool is designed for cutting operations, nesting technology cutting, as well as edge banding and edge leveling 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, and raw and veneered plywood.
