Stepped Double Flute End Mill

A stepped tool means the cutting diameter is larger than the shank diameter. This facilitates a larger cutting diameter for surfacing with spindles using smaller collet sizes. This general-purpose face milling tool is good for surfacing, light depth cuts or heavier cuts with higher torque spindles. The tool is balanced and strong, producing minimal vibrations which translates into good surface finishes. These tools are perfect for aluminum, brass, plastics and exotic composites.

Face mill tools are designed to remove a skim coat off the top of a surface. They generally are not designed for roughing and are very effective in truing up your material or quickly providing an excellent surface finish. These larger diameter long-life, micro-grain carbide tools are available in various cutting diameters and lengths, shank diameters, and geometries for specialty applications.

Article #
The number of cutting flutes in the tool determine how much material can be removed per rotation. For high speed, bulk material removal, single and double flute are recommended. Higher flutes will produce finer finishes, but may require a lower RPM than single flute mills.
Flutes
D1
Nominal cutting diameter of the tool

Cutting Diameter
D2
Shank diameter where the tool is in contact with the holder. D2 diameter can be too large for some machine spindles and smaller diameters may need an adapter to be used with spindles.

Shank
D3= Toric cut diameter is the relief made above the cutting flutes on the neck to allow a tool to have longer reach when milling deeper features. Also known as extended reach.
(D3)
L1
L1 is the total length of the tool from tip to base.
Length
L2
L2 is the length of the usable cutting edge of the tool. This is only the flutes. Also known as flute length. This determines the amount (depth) of material that can be removed per pass.
Cutting Depth
L3
L3= This is the overall reach a tool can be used. Flute plus any relief made by reducing the diameter in D3. AKA known as reach
Reach
Radius of the cutting tip/nose.
Edge Radius
Angle
A= angle of a cutting edge. Drills, engraving tools and countersink tools aka point angle.
