K335

A direct replacement for the Colex T00335 Coroplast Blade 60°, with no holder modification needed. Single edge drag blade for through-cut cutting on Colex flatbed cutting systems.

Sold individually.

Direct OEM replacement

The K335 is a drop-in replacement for the Colex T00335. Same 60° single edge geometry, same flat stock form. No holder changes, no setup adjustments. Order, swap, and cut.

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 on materials like Coroplast and corrugated plastic, where a clean, complete cut is required.

Fine grain tungsten carbide

The K335 is made from fine grain tungsten carbide. For Coroplast and corrugated plastic, that matters. Coroplast has a fluted internal structure that works the blade hard on every pass. Carbide holds an edge longer than standard steel and handles the abrasion of structural plastic without dulling as fast. That translates to more usable cuts per blade before quality starts to drop.

Common questions

How do I know this fits my machine?

The K335 replaces the Colex T00335. If your Colex is running that part number, this is a direct swap. Not sure? Contact Flatbed Tools before you order and we will confirm fit.

What materials does it cut?

The K335 is designed for Coroplast and corrugated plastic. It also cuts self adhesive vinyl, polycarbonate, polyester, masking film, window prep vinyl, magnetic media, and transfer paper. Confirm your cut depth settings match the material before running.

What does "Coroplast Knife" mean?

Coroplast is a twin-wall corrugated polypropylene sheet. The 60° single edge geometry and flat stock form on the K335 are matched to that material. It cuts through cleanly without the blade deflecting into the fluted cells of the sheet. This is a through-cut blade built for structural plastic, not a kiss cut or scoring blade.

How do I know when to replace it?

Watch for drag at the start of cuts, tearing instead of clean separation, or a ragged edge on the Coroplast. If the cut is not releasing cleanly or you are having to recut sections, swap the blade. Carbide holds up well, but Coroplast is abrasive and blades do not last forever.

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?
