Extra Extra Long Ball Nose End Mills

These mills are general purpose carbide mills, with an extra extra long flute length (approx. 7+xD), two or four cutting edges, and a center cutting full radius or "ball" on the end.  The term "general purpose" means that the flutes have a 30° helical spiral and the OD grind has a standard primary and secondary clearance angle.  They can be used for plunging, grooving, side milling, and profile cutting.  They are available uncoated and AlTiN coated.  They are available in a wide variety of diameter sizes from 1/4" to 1" and overall lengths up to 12".
