1/2 4-FLUTE DOUBLE END CARBIDE ENDMILL1/2 4-FLUTE DOUBLE END CARBIDE ENDMILL 4002-0012, 3" OAL, 5/8" LOC, 1/2" SHANK 3"Overall Length,5/8"Length of Cut,1/2"Shank,4-Flute, Double End, Center Cutting. Considered a stub length, these double end endmills are economical because of their shorter length. In addition, the cost to make them is lower because you are using one blank to make two tools! These 4 flute endmills are used for mostly for side milling. The normal width of cut is 10% of the diameter with the height of cut being 1-1/2 times diameter. Thus on a 1/2" endmill the width of cut would be .050" and height of cut .750". Want to slot? That depth of cut would be 1/4" of the diameter, or ,125" on a 1/2" endmill. But we would recommend a 2-fluted endmill which is 1/2 the diameter for depth of cut! Need speeds and feeds? Ask your salesman for details
