Direct OEM replacement

The K46s replaces the Zünd Z46 (3910315), Esko BLD-SF346 (i-346 / G42458406), Gerber MCT SE346 (895346), Colex T00330, and Summa 500-9807 with the same form, same fit, and same geometry. No holder modification needed. If any of these part numbers appear on your current order or in your blade inventory, the K46s is the confirmed drop-in replacement.

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 blade is built for through-cut work. It is not a kiss-cut blade.

Fine grain tungsten carbide construction

The K46s is made from fine grain tungsten carbide. Tungsten carbide holds an edge significantly longer than steel, which means more cuts per blade change and more consistent cut quality across a production run. On demanding materials like corrugated board, carpet, and PET acoustic felt, that difference adds up fast.

Common questions

How do I know this fits my machine?

If your machine uses any of the OEM part numbers listed above, the K46s is a confirmed drop-in replacement. If you are not sure which blade your machine takes, contact us before ordering. We can confirm the right fit before anything ships.

What materials does it cut?

The K46s handles corrugated board, foamboard, folding carton, felt, display board, carpet, sandwich board, honeycomb, sandblasting mask, PET acoustic felt, varnish blankets, 3M VHB, Zintra, and Fsorb. For thinner materials where you need to preserve the liner, a kiss-cut blade is the better call. Not sure which applies to your job? Reach out and we can point you in the right direction.

What does the 45° + 90° cutting angle mean?

The K46s is rated for both 45° and 90° cutting angles. The angle used depends on your machine configuration and the material you are cutting. If you are not sure which applies to your setup, contact us before ordering.

How do I know when to replace it?

Watch cut quality. If the blade is dragging instead of cutting cleanly, tearing material edges, or not releasing cleanly from the liner, it is time to replace. Do not wait until the blade fails completely. A worn blade puts unnecessary stress on the machine and degrades cut quality across an entire run.

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.
