Where to get depth rings

[scott216]

Where can I buy depth rings for some 1/8" bits I have?

What is a depth ring?

Doesn't the Z axis set the depth?

Do you mean a stop collar?
a collar on a bit spinning at 20,000 rpm kind of dangerous?

These things must be anchored well to withstand spindle speed?
Are they applied with a bench press?

Depth setting rings are plastic collars that are securely pressed onto the 1/8 in. shank of a drill bit, end-mill, router bit, or similar rotary cutter. They are 0.20 in. (5.1 mm) thick by 0.25 in. (6.35 mm) dia.. The shank side of the ring (top side in the picture to the right) is accurately positioned (d ±0.004 in.) relative to the tip of the tool. If the shank-side of the ring is pressed against the collet when the tool is loaded, the tip of the bit will be a known distance (d) from the face of the collet. Knowing this distance, the programmer can plunge the tool, confident that the depth of cut will be as expected and will remain the same no matter how many times the tool is changed. If all of the tools in the programmer's magazine have been fitted with depth setting rings, an automatic tool changer can load and unload tools with the tip of each one the same distance from the face of the collet.

Hey Scott, if you place an order with us just put in the notes you want some extra depth rings and we'll throw them in.

Thanks, I've got a few things to order from precisebits. I've been checking out your site, there's a lot good info there.
Is there any sort of standardized color coding for the rings?

Thanks, we try to get as much info out as we can. Although our backlog of stuff to put on the site keeps getting longer.

Only the drills and router bits have color coding here's a link to the legend (Link). Keep in mind I only have the white rings loose on hand. The colored ones are done en masse.
