End mills are used to mill large paths in the FR4 board material. The width of the cutting edge of an end mill is the size of the end mill. FR4 is highly abrasive and requires the use of specialist end mills, PCB Supplies supply 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 hold stock of End Mills ranging between 0.1mm diameter and 3.0mm diameter, all of which have a two flute geometry.
The mill bits are perfect for milling FR-4 circuit board materials. The mill element is fabricated of solid carbide since carbide is the preferred material for milling glass epoxy circuit board laminates due to its exceptional hardness. The mill life is dependent on a number of factors including feed rate, speed, material characteristics, and what the user considers acceptable mill quality. Due to the brittleness of carbide these mill bits are recommended for use with precision equipment. Care must be taken not to drop or flex them as breakage may occur.
Depth Setting RingsWe 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.
