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

Index: SL01.04.015.050.04R

Industrial spiral mill made of solid sintered carbide (VHM) from the SL01 series with compression geometry. The tool is equipped with counter-rotating helical cutting edges, which simultaneously push chips from the top edge down and from the bottom edge up, pressing the laminate against the core of the board. Designed for finishing operations, cutting, jointing, and edge trimming, as well as cutting in nesting technology on CNC machining centres. The compression design eliminates the risk of chipping and tearing on both sides of the workpiece. The ground shank in accuracy class H6 minimizes radial runout, ensuring smooth machining and long spindle life.

Construction advantages and technical properties:

• Compression geometry (Positive-Negative): The combination of right and left twist blades guarantees a smooth, clean edge without tears on both the top and bottom surfaces of the board.
• Finishing edge geometry: Precisely sharpened cutting edges ensure high surface quality without the need for additional finishing operations.
• Monolithic sintered carbide (VHM): The rigid monolithic construction reduces tool deflection under load and helps maintain dimensional accuracy.
• 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 in class G2.5: Balancing in accordance with ISO standards eliminates vibrations at high rotational speeds.

Intended use and range of application:

The tool is intended for cutting operations, nesting technology 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 particle board, as well as raw and veneered plywood.
