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 tools. PCB Supplies supply the highest of quality Tungsten Carbide contour routers.We hold stock of SC/FT Series Routers with rings; these Routers have a right hand, up draft design which lifts debris upwards out of the hole being drilled rather than allowing it to fall into the hole causing the bit to bind and break. These Routers also feature a chip-breaker geometry, this chops the swarf into smaller parts and helps to reduce the radial load on the spiral flute this reducing bird nesting and binding and general wear producing more accurately cut, cleaner edged holes.The SC/FT Series Routers are suitable for peripheral contour routing. This series have a beneficial effect on burr reduction.
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.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.
In use, because the shank-side of the ring is pressed against the collet of the milling or drilling machine when the tool is loaded, the tip of the bit will be at a specific distance form the machine collet. this ensures repeatability when inserting milling bits, especially useful when performing precise processes like Insulation routing (copper removal to create PCB tracks).
If you order a customer distance or a specific colour we will try to keep this information on record, so that next time you order we can make up the order to your standard distance.
