A direct replacement for the Colex T00336 Coroplast Blade 45°, with no holder modification needed. Single edge drag blade for through cutting on Colex flatbed cutting systems.

Sold individually.

Direct OEM replacement

The K336 replaces the Colex T00336 Coroplast Blade 45°. Same 45° single edge geometry, same flat stock form, same holder fit. Drop it in and get back to cutting.

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 a through-cut blade, not a kiss cut blade. If you are cutting to a liner, this is not the blade for that job.

Built for corrugated and demanding materials

Coroplast is corrugated polypropylene sheet, and the fluted structure creates more resistance than flat sheet goods. Standard steel edges wear faster under that load. The K336 is made from fine grain tungsten carbide, which holds a sharp edge longer and handles that friction without degrading quickly. You get more cuts before a swap and cleaner edges throughout the run.

Common questions

How do I know this fits my machine?

If your machine currently uses the Colex T00336 Coroplast Blade 45°, the K336 is the direct replacement. Same geometry, same flat stock form, same holder. Not sure about your current blade part number? Contact us before you order. We will confirm the fit.

What materials does it cut?

The K336 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. For thick or dense material stacks at the edge of that list, contact us and we can confirm whether a different blade geometry is a better call.

Why is it called a Coroplast knife?

Colex named this blade specifically for Coroplast work. The corrugated flute structure resists the blade differently than flat sheet goods do, so Colex engineered a geometry that handles it. The K336 carries that designation forward. It is the right blade for Coroplast and for the other through-cut materials on the list above.

How do I know when to replace it?

Watch for drag, tearing, or pieces that do not release cleanly from the sheet. If cut quality has dropped and parameters have not changed, the blade is the first thing to check. Swap it, run a test piece, and see whether that fixes it before adjusting anything else.

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?
