Three-flute finishing spiral end mill VHM with undercut for 3D models – upward chip removal

Index: SR02.20.040.200.20R

Industrial three-flute spiral end mill made of solid carbide from the SR02 series, with finishing geometry, body undercut, and upward chip removal. Designed for highly precise finishing machining of 3D, shaping deep reliefs and spatial surfaces in aluminium, plastics, and composites. The arrangement of three cutting edges combined with a right-hand screw thread provides high tool rigidity, vibration-free operation, and efficiently removes chips from the cutting bottom. Optimised design with an undercut (neck): The body constriction eliminates the risk of tool collision with the material during deep milling, facilitates free chip removal, and reduces friction, protecting the workpiece from overheating. The ground shank in accuracy class H6 eliminates radial runout, safeguarding the machine drive system.

Key technical parameters and properties:

• Optimised design with an undercut (neck): The body constriction eliminates the risk of tool collision with the material during deep milling, facilitates free chip removal, and reduces friction, protecting the workpiece from overheating.
• Finishing geometry: Precisely ground cutting edges allow for excellent surface quality without the need for additional finishing machining.
• Three-flute design Z3: Three cutting edges allow for an increase in feed speed while maintaining a smooth operation, excellent finish quality, and high tool rigidity.
• Positive geometry: The right-hand spiral lifts the chips upward, protecting the lower edge of the material from scratching.
• Polished chip flutes: The mirror surface of the spiral reduces friction and prevents chips from sticking to the body of the tool.
• Premium solid carbide monolith: The rigid and wear-resistant monolith structure guarantees long tool life and maintains tight dimensional tolerances.
• Optimised roughness of the shank: Low surface roughness of the shank (Ra ≤ 0.3 µm) prevents slippage in the holder and protects the spindle taper.
• Dynamic balancing in class G2.5: Static-dynamic balancing according to ISO/EN standard (class G2.5) guarantees vibration-free operation at very high speeds.

Application and material purpose:

The tool is intended for finishing operations on 3D models, deep cutting, and grooving on CNC machining centres.

Machined materials: Aluminium and composites such as CORIAN and HPL.
