Drills with Rings
All of our drill bits can be purchased with or without rings. If your require your depth rings to be set at a specific height, or you would like us to use a specific colour of ring please let us know after placing your order. 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.
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.
It is important to set the rings at a consistant distance accross all tools of the same type. 
We have a number of available ring colours:
- Red
- Yellow
- Pink
- Green
- Orange
- Purple
- Blue
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).
- Using tool rings, the machine operator can lower the tool, confident that the depth of cut will be as required and repeatable, even when the tool is changed
- Tool Distance Rings are almost always used on machine with automatic tool changers, however many machine operators with manual machines prefer the convenience of the Drill distance Ring.
- Tool Distance Rings can be a savior when using expensive tools (micro drills) where reference surface calibrate may damage or break the tip of the tool.
- Our Drill/Mill bits are available with or without depth setting rings. There is no charge to add the rings, but when ordering it is important to specify the exact distance that you require the rings to be set.
- Distance Rings can be placed on any of the drill bits we supply. If you require any specific ring colours on your tools then please contact our Sales department after placing your order.
If you order a customer specific 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 chosen distance.
