What is kiss cutting?

Kiss cutting means the blade cuts through the face material (the vinyl, film, or label stock) without cutting through the liner underneath. The finished piece peels cleanly from the sheet. The K3 is built specifically for kiss cut work. It is not a through-cut blade.

Fine grain tungsten carbide

The K3 is made from fine grain tungsten carbide, which holds an edge longer than standard carbide and resists chipping under repeated use. For shops running self-adhesive vinyl, masking film, or other thin face materials at volume, edge retention means more usable cuts per blade before quality starts to drop.

Common questions

How do I know this fits my machine?

If your machine uses the Esko BLD-KC103 (i-103 / G42458323), the Zund Z3 (3910115), or the Gerber MCT KC3 (895003), the K3 is a direct fit. Not sure? Contact us before you order.

What materials does it cut?

The K3 is rated for self-adhesive vinyl, polycarbonate, polyester, masking film, window prep vinyl, magnetic media, transfer paper, and 3M VHB. If your application requires cutting through the liner, you need a through-cut blade instead. Contact us if you are unsure which blade fits your job.

What do the cutting angle and wedge angle mean?

The K3 features a 35 degree cutting angle and a 40 degree wedge angle. The 35 degree cutting angle helps the blade track smoothly through the material with reduced drag, while the 40 degree wedge angle provides the right balance of sharpness and edge durability. Together they deliver clean cuts, excellent detail reproduction, and consistent liner protection in demanding production environments.

How do I know when to replace it?

Watch for cut quality changes: dragging through material, tearing instead of cutting clean, or the face material not releasing from the liner. Any of those signs mean the blade is done. Swap before the quality drop creates rework.

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?
