VHM Compression Spiral End Mill Z#liczba_ostrzy_z from the SM01 series – ideal edge quality without chipping

Index: SM01.12.042.090.12R

Industrial spiral end mill made from solid sintered carbide (VHM) from the SM01 series with compression geometry. The tool is equipped with opposing helical cutting edge lines that simultaneously push chips down from the upper edge and up from the lower edge, pressing the laminate to the core of the plate. 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 material being machined. The ground shank in H6 accuracy class minimises radial runout, ensuring smooth machining and long spindle life.

Design advantages and technical properties:

• Compression geometry (Positive-Negative): The combination of right and left-hand twisted cutting edges guarantees a smooth, clean edge without chipping on both the upper and lower surfaces of the plate.
• Finishing cutting edge geometry: Precisely ground cutting edges ensure high surface quality without the need for additional finishing operations.
• Solid sintered carbide (VHM): The rigid monolithic design reduces tool deflection under load and maintains 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 to class G2.5: Balancing in accordance with ISO standards eliminates vibration at high rotational speeds.

Intended use and application range:

The tool is intended for cutting operations, nesting technology cutting, as well as edging and aligning edges 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.
