End Mills

End mills are the cutting tools (bits) that are inserted into the collet of a spindle or router. It is the part that spins and does all of the cutting in all directions. Some end mills can plunge into the material (like drilling). All end mills have the ability to cut sideways (also called profiling).

Single Flute Upcut End Mills:

My personal favorate when cutting plastic or for quiet wood cutting. The cutting speeds can be increased when using these end mills since the chip load cavity is larger than the standard two flute end mills.

1/4" Cut Diameter Single Flute for Plastic and Wood Cutting:

Will create a flat bottom surface
Cut Diameter - 1/4 inch or 6.35mm
Shank diameter - 1/4 inch or 6.35mm

Cut Length - 1/2 inch or 13mm
Cut Length - 3/4 inch or 20mm
Cut Length - 1 inch or 26mm

1/8" Cut Diameter Single Flute for Plastic and Wood Cutting:

Will create a flat bottom surface
Cut Diameter - 1/8 inch or 3.175mm
Shank diameter - 1/4 inch or 6.35mm

Cut Length - 1/2 inch or 13mm
Cut Length - 3/4 inch or 20mm
Cut Length - 1 inch or 26mm

Two Flute Upcut End Mills (General Purpose):

These end mills are the workhorses and will generally cut most materials, but keep an eye on the feedrate.

General Purpose End Mill: Cut Length 1-1/8", 1/4" Diameter

Cut deeply into wood with this extra long length of 1-1/8". Features include, solid carbide (micrograin), 2 flutes, right hand rotation (up cut), overall length of 3", 1/4" shank diameter and 1/4" cut diameter, and a 30 degree helix.

PCB Isolation and Etching End Mills:

These are etching and engraving bits that can be used with non-ferrous metals, hardwoods, phenolics, stabilized woods and composite materials.

60 Degree Tip

This bit features a 1/8" shank 2 flute and 60 degree "V" point tip to cut the really thin grooves needed to isolate traces. This end mill is available uncoated, or ZrN (Zirconium Nitride) coating to extend tool life and increased cut quality.

3D Carving Tools:

For all types of applications including: dimensional signage, 3D carving, 3D contouring and profiling, cabinetry and furniture, and 3D millwork.

1/16" Tip:

Specifications: 1/4" shank, 2" in total length, maximum of .0002" runout, solid submicrograin carbide. Oh yeah, the cut creates a really smooth edge or surface. These are available with or without ZrN coating for longer life.

If you are looking for finer carvings, consider this 3D Carving tool featuring a 1/32" tip.

A few important facts:

  • Overall length or OAL is the total length of the end mill.
  • Flutes are the portion of the end mill that does the cutting with sharp spiral or non spiral edges. Flutes can be up-cut (brings the chips up and out of the cut) or down-cut (forces the chips downward). Up-cut flutes will generally create a nice edge finish on the bottom of the material. Down-cut will create a nice top edge finish.
  • Shank is the portion of the end mill that does not have flutes and is used as the area for collet contact.
  • Most of the measurements will be shank diameter and flute diameter and flute length. Shank diameter is important in that you will need the correct collet to receive the shank. FLute diameter will create the width of the cut, or hole size.
