Direct OEM replacement

The K11s drops in place of the Zünd Z11 (3910309), Summa 500-9803 / G42441204, Esko BLD-DF213, Gerber MCT DE13 (895013), Colex T00313, and Multicam K24. Same form, same fit, same geometry. No holder modification needed.

What is through cutting?

Through cutting means the blade cuts completely through all layers of the material, including any backing or liner. The cut piece separates fully from the sheet. This is not a kiss cut blade. If you need to cut the face material only and leave the liner intact, a kiss cut blade is the right call. If you are cutting fully through, this is the blade for the job.

Fine grain tungsten carbide

The K11s is made from fine grain tungsten carbide, which holds an edge longer than standard carbide in production environments where the machine runs most of the day. More cuts per blade change, cleaner edges over longer runs, and fewer interruptions during a shift.

Common questions

How do I know this fits my machine?

If your machine currently takes a Zünd Z11 (3910309), Summa 500-9803, Esko BLD-DF213, Gerber MCT DE13, Colex T00313, or Multicam K24, the K11s is your direct replacement. If you are not sure which blade your setup takes, reach out before ordering. We would rather confirm the right fit than have you return a blade.

What materials does it cut?

This blade handles self adhesive vinyl, polycarbonate, polyester, masking film, window prep vinyl, magnetic media, transfer paper, and 3M VHB. If you are cutting something not on this list, or running into issues with a material that should be straightforward, contact us. There may be a better blade geometry or a parameter adjustment that solves it.

What does "double edge" mean?

A double edge blade is sharpened on both sides of the cutting point. This allows the blade to cut cleanly in multiple directions without needing to rotate as far between directional changes. For detailed shapes and tight corners, double edge geometry delivers cleaner results and more consistent cut quality across a full production run.

How do I know when to replace it?

Watch the cut quality. When edges start dragging instead of cutting cleanly, the cut piece does not release from the liner the way it should, or you are seeing more tearing than cutting, it is time to swap the blade. A dull blade also stresses the holder and machine, so do not let it run too long past its service life.

Getting the most from your cutting table

A fresh blade is a good start. But if you are going through blades faster than expected, or cut quality has become inconsistent, the blade is rarely the whole story. Cut depth, speed, pressure, and machine condition all affect how long a blade lasts and how clean it cuts.

It is worth asking: When was your machine last serviced? Are your parameters dialed in for this material? Is this the right blade geometry for what you are cutting? Could your operators use time with someone who runs these machines every day?

Flatbed Tools offers machine service, preventive maintenance, operator training, and workflow consulting. If something is not cutting right, reach out. We have probably seen it before.
