Ø 3mm to 30mm
M2-AL HSS High Speed Steel Three Flute Spiral Router Bit End Mill CNC Milling Cutter for Aluminum 
 
High-quality materials, excellent craftsmanship, safe, reliable and durable, long service life, wear resistance, high hardness, sharp and high cutting efficiency. Many size and complete specifications, convenient and flexible installation, convenient maintenance and better cost performance.  
 
These high speed steel three-flute cutters were specially developed for machining aluminum.
 
Full grinding, spiral groove, large amount of chip remove, avoid sticking blade, significantly improve production efficiency.
 
The universal chamfered round shank is easy to use, has good compatibility, enhances the anti-vibration and cutting speed of the milling cutter, and makes the clamping firmer without slipping.

● Exact dimensions can also be viewed in the photo gallery. 
 
● Use Tips:
1. Appropriately reduce the cutting speed and feed rate, which can prolong the service life of the milling cutter.
2. When working, it is necessary to add cutting fluid to protect the knife edge, so that the cutting is smoother.
3. When the oxide film or other hardened layer remains on the surface of the workpiece, it can be cleared by up-milling.
4. Before using the tool, please measure the tool deflection accuracy. When the tool deflection accuracy exceeds 0.01mm, please correct it before cutting.
5. The shorter the length of the tool protruding from the chuck, the better. If the tool protrudes longer, the rotation speed, feed speed or cutting amount should be reduced.
6. During cutting, if abnormal vibration or noise occurs, please reduce the speed and cutting volume until the situation improves.
