Oscillating Knife Blades for Zünd, AOL & JWEI Cutters

Oscillating knife blades cross-referenced by model code: 35 Zünd profiles from Z1 to Z104, 36 JWEI profiles from J303 to J603, and 49 AOL profiles across the C, LC, T, Y, Z, ZP and ZS groups. Every one is a replacement part we grind to the same outline and thickness as the blade it replaces.

1. Why the model code matters more than the size

Two oscillating blades can share an identical outline — say 38 × 6.35 mm — and still be different parts. One may be 0.64 mm stock with a 10° edge for thick foam, the other 1.0 mm stock with a 16° edge for board. Put the wrong one in the holder and it either will not seat or it will not cut cleanly, and no amount of adjusting the machine will fix it.

That is why this page is organised by code. If you know the code stamped on your blade or printed in the machine’s manual, you can find the replacement in one step. If you do not, measure it and photograph it — we will identify it for you.

2. Which blade goes on which machine

3. Zünd oscillating knife blades: Z1 to Z104

The Z series is the deepest catalogue on the site. The same physical size often appears under several codes because the edge geometry differs — Z16 and Z17 are both 25 × 5.6 × 0.63 mm, but one carries a 36° edge and the other a 25° edge.

Full Z-series table. Custom sizes are quoted from a drawing or a sample.

If your code is not here, it may be a newer profile or a machine-specific variant. Send the stamped number and we will confirm whether it is a standard grind, a modified standard, or something we need to make from a sample.

4. JWEI blades: J303 to J603

The J series runs from very small detail blades (J323 and J603 at 22 × 5.5 mm with a 45–60° edge) up to long tangential knives such as J351 at 61.1 × 19 × 1.0 mm. Note that several codes describe the same size with a different edge:

5. AOL vibrating knife blades: six model groups

The AOL catalogue is organised by prefix rather than by a single running number, and the prefixes carry meaning — the body length and the mounting change between groups even where the cutting length looks similar.

Grouped by model prefix. The complete 49-profile list, with every size, is on the AOL vibrating knife page.

First 16 profiles, in model order.

6. Choosing the thickness: 0.63, 1.0 or 1.5 mm

Thickness is not a preference. It is set by the holder on your machine, and fitting a blade of the wrong stock thickness will either damage the holder or leave the blade free to deflect.

Where a code exists in more than one thickness — and several do — the thickness in the code name is part of the part number, not an option. Check the holder before you order the cheaper of the two.

7. Edge angle: the same outline, a different cut

Included angle trades sharpness against strength. A narrow angle gives a keener edge that separates soft material cleanly but folds over on hard material; a wide angle survives impact but pushes rather than slices.

8. What to send for a match

• The model code, stamped on the blade or listed in the machine manual — fastest route by far.
• A photo with a ruler across the blade, taken flat, in focus. Nine out of ten unidentified blades can be matched from this alone.
• Thickness in mm, measured with a caliper. Do not infer it from the model number unless you are sure of the series.
• The material being cut and the machine’s cutting mode (oscillating, tangential, drag), because it decides the edge angle even when the outline is fixed.
• Quantity per year, if you want the price for a repeating order rather than a single blade.
