Free sprocket DXF
ISO 606 roller chain, 06B to 72B, 9 to 150 teeth. Give it the chain number and the tooth count. You get a plate sprocket for laser or waterjet, drawn in true arcs.
Built from the standard and checked against it: 1196 chain and tooth-count combinations build, and every one checks itself before you get it.

What you get
- True arcs, no splinesA seating arc and two flank arcs for each gap, a tip arc on each tooth. It cuts cleanly on older controllers.
- The middle of the ISO bandISO 606 permits a band of tooth gaps. The generator builds its middle, not the edge.
- Checked before you get itThe roller sits on the pitch circle, the pitch equals the chain's, and the over-pins figure matches the standard. If a check fails, no file.
- Your plate, your machineStructural plate as cut, or wear plate on waterjet. Lightening holes on large sprockets where the web still beats the chain.
Sizes · tip diameter in mm
14 chains · ISO 606 preferred tooth countsA diameter opens the generator with that chain and tooth count filled in. Any count in a chain's range builds, not only the preferred ones in the table. A dash means the generator refuses that size; hover it to see why. Plate is the stock thickness for that chain's tooth width.
Questions
Is the sprocket DXF really free?
Yes. Pick the chain number and the tooth count, and the generator builds the file. No sign-up, no payment.
Which chains does it cover?
ISO 606 B-series simplex roller chain (the European series), 06B to 72B. The chain number is stamped on the link plates. ANSI A-series chain is not in this release.
How many teeth can I have?
ISO 606 covers 9 to 150 teeth. Small sprockets stop where a flat plate leaves no room for a usable bore (they need a hub, which this generator does not make yet), and large ones stop at the sheet size. The table shows the range each chain builds.
Is the tooth shape correct?
ISO 606 sets a band of permitted tooth gaps. The generator builds the middle of that band from true arcs, and every file checks itself before you get it: the roller seats on the pitch circle, the chordal pitch equals the chain pitch, and the measurement over pins matches the standard's formula.
Can I cut it from hardened plate?
Yes, from wear-resistant plate, on waterjet only. A laser softens the tooth flank, which is the surface the roller wears on.
Is the sprocket rated for a drive load?
No. On a plate sprocket the chain is the weak link, so there is no drive rating. Where lightening holes are offered, the lightened web is checked to stay stronger than the chain.
