Bimetallic spiral end mill VHM with ball head for aluminium and plastics with upward chip removal – for sculpting and 3D machining

Index: SQ31.04.012.060.06R

Industrial bimetallic spiral end mill made of solid carbide (VHM) with a ball geometry (Round Nose) and upward chip removal (positive). The arrangement of two cutting edges (Z2) with a full radius on the fronts enables precise shape milling, sculpting, engraving, and machining of curved surfaces in 3D without leaving sharp ledges. The right-hand spiral effectively lifts the chips upwards, preventing accumulation in the cutting zone. Dedicated to finishing, cutting, and joining tasks in aluminium, plastics, and composite materials on CNC machining centres and overhead milling machines. The finishing geometry combined with polished chip grooves prevents the accumulation of chips on the tool body. The ground shank in class H6 accuracy eliminates radial runout, protecting the machine's drive system.

Design advantages and technical properties:

• Ball geometry (Round Nose): Full radius on the tool's tips allows for precise 3D modelling, machining of spatial surfaces, and smooth transitions in internal radii.
• Bimetallic Z2 construction (positive): Two cutting edges increase the rigidity of the tool and allow for efficient work with smooth guidance in the material.
• Positive geometry (upward chip removal): Right-hand spiral lifts the chips upward, protecting the lower machined surface from scratches caused by chips.
• Polished chip grooves: The mirror surface of the spiral reduces friction and effectively prevents the accumulation of chips on the tool body.
• Solid carbide (VHM): Rigid and wear-resistant structure of the solid reduces vibrations and guarantees dimensional stability for precise details.
• Low roughness of the shank (Ra ≤ 0.3 µm): Ground surface of the shank prevents slipping in the holder and protects the spindle taper from wear.
• Dynamic balancing in class G2.5: Balancing according to ISO standards guarantees vibration-free operation at very high speeds.

Purpose and field of application:

The tool is intended for 3D finishing, sculpting, engraving, cutting, and joining in aluminium and plastics on CNC machining centres.

Used in the processing of materials such as: aluminium, plastics, and composites like CORIAN® and HPL.
