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. The K50 is built for through-cut work on fabrics and textiles. It is not a kiss-cut blade.
Fine grain tungsten carbide construction
The K50 is made from fine grain tungsten carbide. The tighter grain structure holds a sharp edge longer than standard carbide, which matters when you are running fibrous materials like aramid dry fiber, woven nylon, or carbon dry fiber. Cleaner cuts per shift, fewer blade changes, and consistent edge quality through longer runs.
Common questions
How do I know this fits my machine?
Match the K50 against your current OEM blade. It replaces the Zund Z50 (3910335), Esko BLD-RC110 (G42444844), Gerber MCT R50, Summa 500-9860, Colex T00360, iEcho E50, and Kuris 83906. If your part number is on that list, you are good. Not sure? Contact us before you order.
What materials does it cut?
The K50 is designed for fabrics, textiles, canvas, woven and knit nylon, woven and knit polyester, aramid dry fiber, glass dry fiber, carbon dry fiber, and felt. If you are cutting harder semi-rigid or rigid materials, a different blade geometry is the right call. Reach out and we can point you in the right direction.
What does 10-sided (decagonal) mean?
The K50 uses a decagonal wheel with 10 cutting facets rather than a smooth-edged disc. As the wheel rotates, each facet presents a fresh cutting angle. On fibrous materials like dry fiber and woven textiles, where a worn edge shows up fast in cut quality, that consistent geometry makes a difference across longer runs.
How do I know when to replace it?
Watch the cut edge. On textiles and woven materials, a dull wheel leaves frayed edges, skipped cuts, or material that pulls instead of separating cleanly. If you are seeing any of those, swap the blade before the issue compounds into a material waste problem.
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?
