Specification Brand : uxcell BulletPoint1 : Product Name : PCB End Mill;RotationType : Left Handed BulletPoint2 : Cutting Diameter : 1.5mm/ 0.06";Cutting Edge Depth : 8.5mm/ 0.33" BulletPoint3 : Shank Diameter : 3.175mm/ 0.125";Total Length : 38mm/ 1.5" BulletPoint4 : Main Color : Gold Tone, Silver Tone;Material : Titanium Coated,Tungsten Carbide. The longer the length of the tool clamped by the chuck, the better. If the clamping length is shorter, you need to lower the feed rate and cutting speed to reduce vibration and extend the tool life. BulletPoint5 : Weight : 37g;Package : 5 x PCB End Mill1 x Plastic Case. Combined with the material to be processed, select an appropriate feed rate and cutting speed to improve the tool life and obtain better processing accuracy and performance.
