Multi Thread Mill

The multi-thread mill can thread a hole more quickly than a standard thread mill. The multiple cutting teeth achieve a very good quality, exact thread in just one revolution. They are not recommended for steel.

Thread milling is when a tool is used to helix and machine either an internal or an external thread. Thread milling offers distinct advantages compared to tapping, such as:

  • Higher quality and cleaner threaded grooves
  • More control on the tolerance or size of the thread
  • Burr-free edges with a bevel to assist with a lead-in

We offer a wide range of micro-grain carbide tools that can create thread sizes as small as 1-64 UNC or M1 Metric threads.

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.
