Three-Edge Spiral Cutting Tool VHM Roughing End Mill with Neck for 3D Models – Chip Ejection Upwards

Index: SR34.16.040.200.16R

Industrial roughing end mill made from a solid piece of sintered carbide (VHM) with profiled cutting edges, a necked body, and upward chip ejection (positive geometry). Designed for efficient preliminary machining, deep cutting, and moulding of dies and 3D models in aluminium, plastics, and composites. The chip breaker reduces the cut material into smaller pieces, which limits cutting resistance, reduces vibrations, and prevents clogging of chip channels. The necked body eliminates the risk of the clamping part rubbing against the material walls during deep cutting. The right-hand spiral effectively removes the cut material from the cutting edge, ensuring a clean working environment. The ground shank in H6 tolerance guarantees axial accuracy and protects the CNC machine spindle.

Construction Features and Technical Properties:

• Necked design: The necked body prevents collisions with the material during deep milling, facilitates chip removal, and reduces friction.
• Roughing geometry with chip breaker: The profiled blades divide the cut material into fine particles, reducing cutting resistance and preventing chip jamming.
• Three-edge setup (Z3): Three cutting edges ensure a high level of rigidity, allowing for operation at higher feed rates.
• Chip evacuation upwards (positive): The right-hand chip channel lifts dust and chips, protecting the cutting edge base and underside of the material from damage.
• Polished chip grooves: The smooth spiral surface reduces friction and prevents aluminium from sticking to the body.
• Solid sintered carbide (VHM): The rigid structure dampens vibrations and provides long tool life when machining with large allowances.
• Low shank roughness (Ra ≤ 0.3 µm): The ground shank prevents slipping in the collet and protects the spindle cone from wear.
• Dynamic balancing G2.5: Compliance with ISO standards allows for safe and smooth operation at very high speeds.

Intended Use and Application Range:

The tool is intended for rough cutting, deep profiling, welding, and preliminary shaping of 3D models on CNC machines.

Used for machining materials such as: aluminium, plastics, and composite boards like CORIAN® and HPL.
