VHM spiral end mill compression finishing Z#number_of_edges_z from the SN01 series – ideal edge quality without chipping

Index: SN01.20.100.165.20R

Industrial spiral end mill made from solid sintered carbide (VHM) from the SN01 series with compression geometry. The tool features opposing helical cutting edges, which simultaneously push chips down from the upper edge and up from the lower edge, pressing the laminate against the core of the board. Designed for finishing operations, cutting, jointing and edge trimming as well as nesting 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 accuracy class H6 reduces radial runout, ensuring smooth processing and long spindle life.

Design advantages and technical properties:

• Compression geometry (Positive-Negative): The combination of right-hand and left-hand spiral cutting edges guarantees a smooth, clean edge without chipping on both the upper and lower surfaces of the board.
• Finishing geometry of the cutting edges: Precisely ground cutting edges ensure high surface quality without the need for additional finishing operations.
• Solid sintered carbide (VHM): 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 in class G2.5: Balancing according to ISO standards eliminates vibrations at high rotational speeds.

Intended use and application range:

The tool is designed for cutting operations, nesting cutting, as well as jointing and edge trimming 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, as well as raw and veneered plywood.
