Carbide End Mills

End mills are used to mill large paths in the FR4 board material. For small insulation paths micro-Cutters should be used. The width of the cut is determined by the size of the end mill. We hold stock of End Mills ranging between 0.1mm diameter and 3.0mm diameter, all of which have a two flute geometry, 4 Flute as an option. Square End or Fishtail.

FR4 PCB material is highly abrasive and requires the use of specialist end mills, PCB Supplies provides the highest of quality End Mills made of high grade Tungsten Carbide which feature very high cutting performances whilst maintaining the tightest production tolerances.

We recommend that bits are fitted with depth setting rings. This will allow you to set the plunge depth stop on your drill press to a single value that will work for all bit diameters.

All of our bits can be purchased with or without rings. When ordering drills with depth rings, you may specify the depth ring position to suit your requirements.

Of interest to some, will be our ability to supply Nano Tools
