Drill depth-stop collar set

A drill depth-stop collar slides onto a twist bit and stops the chuck from driving deeper than you want, so dowel holes, hinge cups and pilot holes all end at the same depth. A good set covers bits from 3 to 10 mm, with a bore 0.2 mm over the nominal size, a 12 mm outer diameter for grip and a side hole for an M3 grub screw. Print the collars standing up so the bore stays round, and choose PETG if the bit gets warm.

Instead of digging through repositories for a set that happens to match your bits, describe the exact diameters and lengths you use and SpeakCAD models them for you. If a bore is snug, ask for 0.1 mm more clearance in the chat and regenerate. Previewing costs nothing and works in your browser.

Design a set of 5 drill depth-stop collars for bit diameters 3, 4, 5, 6 and 8 mm. Each collar is 15 mm long, 12 mm outer diameter, bore 0.2 mm larger than the bit, with a radial M3 grub-screw hole and hex nut pocket.

Change any number to match what you measured. The AI keeps the rest of the design consistent, and small follow-up edits after a download are free.
