K52
A direct replacement for the Blumer E52, Gerber MCT R52 / R52-V, iEcho E52, Summa 500-9862, and Zund Z52 (3910337), with no holder modification needed. Rotary wheel blade for through cutting on Blumer, Colex, Esko, Gerber / MCT, iEcho, Multicam, Summa, and Zund flatbed cutting systems.
Sold individually.
Direct OEM replacement
The K52 matches the Blumer E52, Gerber MCT R52 / R52-V, iEcho E52, Summa 500-9862, and Zund Z52 (3910337) in form, fit, and geometry. No holder modification required. If you are running any of those part numbers, the K52 drops straight in.
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 full cut, not a kiss cut or score.
Fine grain tungsten carbide construction
The K52 is machined from fine grain tungsten carbide. Carbide stays sharp longer than steel on abrasive materials like woven technical textiles and dry fiber composites, and holds its edge through high-cycle production runs. More cuts per shift before the blade needs swapping.
Common questions
How do I know this fits my machine?
If your machine uses the Blumer E52, Gerber MCT R52 or R52-V, iEcho E52, Summa 500-9862, or Zund Z52 (3910337), the K52 is a direct replacement. Not sure? Contact us before you order.
What materials does it cut?
The K52 is built for textiles and technical dry fiber materials: fabrics, canvas, woven and knit nylon, woven and knit polyester, aramid dry fiber, glass dry fiber, carbon dry fiber, and felt. Cutting something outside this list? Reach out and we will tell you whether it is a fit.
What does "decagonal" (10-sided) mean?
The K52 is shaped with 10 flat facets around its circumference rather than a smooth round edge. Each facet is a cutting surface. As the wheel rolls along the cut path, those surfaces do the work. The decagonal geometry helps the blade track consistently through material and maintains clean edge engagement across the cut.
How do I know when to replace it?
Watch for dragging through material, torn or ragged edges, or incomplete cut separation. When cut quality drops and adjusting speed and pressure does not recover it, it is time to swap the blade.
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?
