Commodity Brief
Spiral Small Diameter End Mill 
UN US Standard (internal)(3-tooth)
◼ 3 times the effective length.

◼ Accurate tolerance range, no need to consider the problem of tooth pitch,which makes processing more convenient.

◼ Titanium-silicon coating on the back,Excellent bending resistance and excellent cutting angle make it easy to machine difficult-to-machine materials.

◼ The cutting resistance is low and the chips are short,and the tool is not easy to break during processing. It can be easily removed without damaging the workpiece, which greatly reduces the processing risk.
