VHM Compression Finishing Spiral End Mill Z#number_of_edges_z from the SM01 series – perfect edge quality without chipping

Index: SM01.12.025.070.12R

Industrial spiral end mill made from solid carbide (VHM) from the SM01 series with compression geometry. The tool is equipped with opposing screw lines of the cutting edges, which simultaneously push the chip down from the upper edge and up from the lower edge, pressing the laminate against the plate core. Designed for finishing operations, cutting, edging and aligning edges 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 workpiece material. The ground shank in class H6 reduces radial runout, ensuring smooth machining and a long spindle life.

Design Advantages and Technical Properties:

• Compression Geometry (Positive-Negative): The combination of right-hand and left-hand twisted edges guarantees a smooth, clean edge without chipping on both the upper and lower surfaces of the plate.
• Finishing 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 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 in Class G2.5: Balancing in accordance with ISO standards eliminates vibrations at high rotational speeds.

Intended Use and Application Range:

The tool is intended for operations such as cutting, nesting technology cutting, edging and aligning edges on CNC machines.

It performs excellently when 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.
