Product Overview
This is a solid carbide end mill designed for high-speed milling of aluminum and other non-ferrous metals. It is engineered for stable performance during finishing and semi-finishing operations. The tool is made from tungsten carbide with a hardness of HRC55 and features a 3-flute design to ensure smooth chip removal and high surface quality. It is suitable for use in various milling machines and can be produced to customer drawings or samples.
Key Benefits
- High hardness HRC55 ensures long tool life in aluminum machining
- 3-flute design provides smooth chip removal and stable cutting
- Good symmetry and dynamic balance for high-speed milling without vibration
- Sharp edge and high rigidity maintain cutting accuracy and surface finish
- Reduced tool change frequency due to extended service life

Problems It Solves
- Rapid tool wear in aluminum due to built-up edge and soft material galling
- Poor chip evacuation leading to re-cutting and surface defects
- Vibration and chatter at high speeds due to poor dynamic balance
- Inconsistent surface finish from dull or misaligned cutting edges
- Frequent tool changes increasing downtime and production cost
Who It Is For

Packaging and shipping
Quality Control
- Physical properties, shape and tolerance are checked before shipping
- Every order is tested before bulk production is released
- Inspection photographs of the finished order are sent for confirmation before delivery
Use Guide
- Use appropriate cutting speed and feed rate for aluminum to avoid built-up edge
- Ensure proper coolant or air blast to remove chips and reduce heat
- Use a rigid setup to prevent vibration and chatter
- Inspect the tool after each use for edge wear or chipping
- Keep a sample from the first batch for comparison in future orders
How It Compares With The Alternatives
| Alternative | Trade-off |
|---|---|
| High-speed steel end mill | HSS wears faster in aluminum, especially at high speeds; carbide maintains edge integrity and lasts longer |
| 2-flute end mill for aluminum | 2-flute tools have better chip clearance but lower rigidity and are more prone to chatter; 3-flute offers better balance for finishing |
| Coated carbide end mill | Coating can wear through and expose base material; solid carbide maintains consistent performance throughout tool life |
