K16n

A direct replacement for the Summa 500-9800, with no holder modification needed. Single edge drag blade for through cutting on Summa F Series flatbed cutting systems.

Sold individually.

Direct OEM replacement

The K16n matches the Summa 500-9800 in form, fit, and geometry. If your F Series is currently running the 500-9800, the K16n drops in without any adjustment to your holder or tooling head. Same geometry, same cut. Not sure this is the right part? Contact us before you order.

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. The K16n is built for this work. It is not a kiss cut blade.

Fine grain tungsten carbide

The K16n is made from fine grain tungsten carbide. Carbide holds an edge significantly longer than tool steel, which matters when you are cutting abrasive materials or running high-volume jobs. More consistent cut quality across a shift, fewer blade changes per job.

Common questions

How do I know this fits my machine?

The K16n is a direct replacement for the Summa 500-9800. If your Summa F Series is currently running that OEM part number, this blade fits. If you are not certain, contact us before ordering and we will confirm.

What materials does it cut?

The K16n is rated for self adhesive vinyl, polycarbonate, polyester, masking film, window prep vinyl, magnetic media, transfer paper, 3M VHB, corrugate, foamboard, folding carton, sandblasting mask, and varnish blankets. If you are cutting something not on that list, reach out and we can tell you whether this blade or a different geometry is the better call.

What does the 54° cutting angle mean?

The 54° cutting angle describes the grind on the blade edge. A steeper angle gives you more edge durability when cutting heavier or abrasive materials. The K16n is a single edge blade, meaning one face is ground and one is flat. That geometry tracks cleanly in the drag direction and holds up well across the range of materials this blade is rated for.

How do I know when to replace it?

Watch for drag on lighter materials, torn or ragged cut edges, or material not separating cleanly from the sheet. If cut quality has dropped and adjusting depth or pressure does not fix it, the blade is ready to swap.

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.
