END MILL TYPE AND GEOMETRY

y PERIPHERAL CUTTING EDGE

TypeShapeFeature
Ordinary FluteRegular flute geometry as shown is most commonly used for roughing and finishing of side milling, slotting and shoulder milling.
Tapered FluteA tapered flute geometry is used for special applications such as mold drafts and for applying taper angles after conventional straight edged milling.
Roughing FluteRoughing type geometry has a wave like edge form and breaks the material into small chips. Additionally the cutting resistance is low enabling high feed rates when roughing. The inside face of the flute is suitable for regrinding.
Formed FluteSpecial form geometry as shown is used for producing corner radii on components. There are an infinite number of different geometry's that can be manufactured using such style of cutters.

y END CUTTING EDGE

TypeShapeFeature
Square End (With Center Hole)Generally used for side milling, slotting and shoulder milling. Plunge cutting is not possible due to the center hole that is used to ensure accurate grinding and regrinding of the tool.
Square End (Center Cut)Generally used for side milling, slotting and shoulder milling. Plunge cutting is possible and greater plunge cutting efficiency is obtained when using fewer flutes. Regrinding on the flank face can be done.
Ball EndGeometry completely suited for curved surface milling. At the extreme end point the chip pocket is very small leading to inefficient chip evacuation.
Corner Radius EndUsed for radius profiling and corner radius milling. When pick feed milling an end mill with a large diameter and small corner radius can be efficiently used.

y SHANK AND NECK PARTS

TypeShapeFeature
Standard (Straight Shank)Most widely used type.
Long ShankLong shank type for deep pocket and shoulder applications.
Long NeckLong neck geometry can be used for deep slotting and is also suitable for boring.
Taper NeckLong taper neck features are best utilized on deep slotting and mold draft applications.
