Spiral router bit Finishing VHM Z2 D16 I55 L110 S16 RH positive

Dual-edged spiral ball mill VHM positive from the SI01 series – precise sculpting and 3D machining

Index: SI01.16.055.110.16R

Industrial spiral ball mill made from solid sintered carbide (VHM) from the SI01 series, featuring positive geometry (chip removal upwards). Designed for precise sculpting, machining of 3D models, cutting, as well as edging and alignment on CNC machining centres and overhead milling machines. The ball-shaped front radius combined with finishing cutter geometry (Z2) enables the achievement of perfectly smooth, seamless surface transitions when machining bas-reliefs and spatial forms in 3D. The right-hand screw line efficiently evacuates chips upwards, protecting the cutting zone from overheating. The ground shank in H6 accuracy class eliminates radial runout, protecting the drive system and ensuring high process stability.

Structural advantages and technical properties:

• Dual-edged ball design Z2 (positive): The rounded front profile allows for precise shape milling, bas-relief sculpting, and 3D spatial modelling.
• Positive construction with upward chip evacuation: The right-hand spiral efficiently removes chips from deep grooves and 3D spaces, providing a clean bottom edge of the work material.
• Finishing cutter geometry: Precisely ground cutting edges guarantee a high surface finish standard without the need for manual grinding.
• Monolithic sintered carbide (VHM): The rigid monolithic construction reduces tool deflection under load and allows for 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 G2.5 class: Balancing in accordance with ISO standards guarantees stability and quiet operation at maximum rotational speeds.

Purpose and area of application:

The tool is intended for milling operations of 3D models, sculpting, cutting, and edging and aligning on CNC machines.

It works excellently in the machining of materials such as: soft and hardwood, raw MDF board, raw particle board, and plywood.
