      Printed circuit boards are usually made of fiberglass (FR4), which is highly abrasive and given the many hundreds or thousands of holes on modern circuit boards, requires the use of specialist drill bits. PCB Supplies supplies the highest of quality Drill Bits manufactured by Union Tools. These Drill Bits are made of top quality Tungsten Carbide.

      We hold stock of standard drills in the ST and UC Series. The ST Series are a universal drill bit witch can be used for many materials. The UC Series bits are and undercut bit which is used for small through holes or via interconnectors, they allow improved inner hole wall quality, whilst maintaining good registration accuracy. This makes them ideal for high density multilayer boards.

      We also stock Extended Flute Drills of the STX series which have elongated flutes in comparison to the equivalent standard version in the same diameter.

      Finally we stock Micro Drills in the MV and MC Series these are ideal for through holes and blind via hole drilling. These drills are made of hyper fine grade carbide alloy to ensure they are robust.

      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.

      Dust and mist created by drilling, milling and other activities may release chemicals and residue from the materials and tools that could cause adverse health effects.

      Drill Distance Rings are plastic collars that are set precisely onto the shank of a drill bit, end-mill or router bit. The ring is positioned relative to the tip of the tool, the positioning is micrometer set for precise distance setting.

      We can provide tool rings for automatic tool change systems and LPKF "S" series machines, such as ProtoMat S62, ProtoMat 95s and LPKF 101 Hi-P Automill systems.

      We have a number of available ring colours: ...
