K140r

A direct replacement for the Esko BLD-SR8140 and Gerber / MCT G42455899 (42455899), with no holder modification needed. Single edge drag blade for through cutting on Esko and Gerber / MCT flatbed cutting systems.

Sold individually.

Direct OEM replacement

The K140R replaces the Esko BLD-SR8140 and the Gerber / MCT G42455899 / 42455899 directly. Same form, same fit, same 8.00mm round stock geometry. No holder modification needed. If you need to confirm fit for your specific machine setup, contact us before ordering.

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 the right blade when you need clean separation on polycarbonate, magnetic media, heavier vinyls, and similar materials where the material needs to separate completely rather than stay on a liner.

Fine grain tungsten carbide

The K140R is ground from fine grain tungsten carbide. Carbide holds an edge longer than tool steel under repeated contact with abrasive materials. In production environments cutting vinyl, polycarbonate, or magnetic media across multiple shifts, that means more cuts before a swap and more consistent cut quality through a longer run.

Common questions

How do I know this fits my machine?

The K140R directly replaces Esko BLD-SR8140 and Gerber / MCT G42455899 / 42455899. If your machine is currently running one of those blades, this is the drop-in replacement. Not sure? Contact us before you order.

What materials does it cut?

This blade is designed for through cutting on self adhesive vinyl, polycarbonate, polyester, masking film, window prep vinyl, magnetic media, transfer paper, and 3M VHB. For applications that require kiss cutting rather than through cutting, a different blade geometry is the better call. Contact us if you are unsure which applies to your work.

What does the 40° cutting angle mean for my application?

The 40° single edge geometry gives the K140R clean tracking through the cut path with good control across a range of film and vinyl materials. It is balanced for the mix of materials this blade is built to cut. If you are cutting something with very different characteristics and want to confirm this is the right geometry, reach out.

How do I know when to replace it?

Watch your cut quality. If the blade is dragging through the material rather than cutting it, tearing the edge rather than slicing it, or cut material is not releasing cleanly, the blade is due for a swap. Running a worn blade puts extra stress on the machine and produces scrap.

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.
