Tool Type: V-BitDiameter (D) = 0.1250"Included Angle (A, total angle)
45° - 0.075" (1.92mm)
60° - 0.054" (1.38mm)
Stepover (for final cleanup pass) = 0.002" (0.13mm)Stepover (for roughing, clearance pass) = 0.005" (0.25mm)Spindle RPM (SPEED) = 5 KRPM to 60 KRPMFeedrate (IPM) = Depends on the material being cut. (see articles section)Plunge rate = 5 IPM to 25 IPM (again depending on material being cut)
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.
