K17n
A direct replacement for the Summa F Series (500-9801), with no holder modification needed. Single edge drag blade for through cutting on Summa flatbed cutting systems.
Sold individually.
Direct OEM replacement
The K17N crosses directly to the Summa F Series (500-9801). Same form, same fit, same 65° single edge geometry. Nothing changes in your holder setup. If you are running the Summa F Series and your machine takes the 500-9801, this is your blade.
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. If you need a clean, full-depth cut, this is the right blade. It is not a kiss cut blade and is not designed to leave a liner intact.
Fine grain tungsten carbide
The K17N is ground from fine grain tungsten carbide. Carbide holds an edge significantly longer than steel under production conditions, which means more cuts per shift and fewer change-outs. On harder materials like polycarbonate, foamboard, and magnetic media, that edge durability makes a difference you will notice over the course of a production run.
Common questions
How do I know this fits my machine?
The K17N replaces the Summa F Series (500-9801). If your machine uses that part number, this blade fits with no modification. Not sure? Reach out before you order and we will confirm compatibility.
What materials does it cut?
The K17N handles 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 outside that list or working with unusual thicknesses, contact us. We can tell you whether this blade is the right call or whether a different geometry fits your job better.
What does the 65° cutting angle mean?
The 65° is the angle at which the blade edge contacts the material. At 65°, the K17N carries a broader edge than a shallower-angle blade. That broader edge is more durable on materials with body, corrugate, foamboard, polycarbonate, where a finer point would wear faster. It is also why this blade handles such a wide range of materials without sacrificing edge life.
How do I know when to replace it?
Watch the cut quality. If the blade is dragging rather than tracking cleanly, leaving ragged edges, or failing to release from the liner, it is time to swap it out. Do not wait for a full cut failure. Quality drops before the blade stops cutting entirely.
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.
