Spiral router bit for acrylic & plastics VHM Z1 D2 I6 L60 S6 RH Finishing negative

Single-blade spiral end mill VHM for PLEXI with downward chip removal – ideal upper edge

Index: ST51.02.006.060.06R

Industrial single-blade spiral end mill made of sintered carbide (VHM) with negative geometry (downward chip removal). Designed for precise cutting, edge jointing and finishing, grooving and routing in plexiglass, plastics and composites on CNC machines and overhead milling machines. The left-handed helical flute presses the workpiece against the table and removes chips downwards, which works perfectly for machining small parts and flimsy sheets of material. The special finishing geometry with one blade (Z1) combined with a polished chip flute effectively prevents material sticking and melting, ensuring a perfectly finished upper surface edge. The ground shank with H6 accuracy class eliminates radial runout, protecting the machine's drive system.

Design advantages and technical properties:

• Single-blade Z1 design (negative): The single cutting blade efficiently removes chips downwards, stabilising the material on the work table.
• Polished chip flute: The mirror-like surface of the spiral counteracts chip sticking and re-welding of chips to the body.
• Finishing blade geometry: Precisely ground edge ensures perfect edge quality without fraying or damage on the upper surface.
• Sintered carbide (VHM): High structural rigidity of VHM eliminates vibrations and maintains dimensional stability.
• Low shank roughness (Ra ≤ 0.3 µm): The ground surface of the shank protects the holder and spindle taper from wear and prevents slippage.
• Dynamic balancing in class G2.5: Balancing according to ISO standards guarantees vibration-free operation at very high speeds.

Intended use and applications:

The tool is intended for cutting, edge jointing and finishing, grooving and routing in plastics on CNC machining centres.

Used for machining materials such as: PLEXI (acrylic), plastics, ALUCOBOND® sheets, ALUCOBOND® A2 and composites like CORIAN® and HPL.
