K22
A direct replacement for the Esko BLD-SF422 (i-422 / G42458265), Zünd Z22 (3910315), Gerber MCT SE22 (895022), and Summa L25 (500-9810 / 22), with no holder modification needed. Single edge oscillating flat-stock blade for through cutting on Colex, Esko, Gerber / MCT, Kongsberg, Multicam, Summa, and Zund flatbed cutting systems.
Sold individually.
Direct OEM replacement
The K22 matches the Esko BLD-SF422 (also listed as i-422 and G42458265), the Zünd Z22 (3910315), the Gerber MCT SE22 (895022), and the Summa L25 blade (500-9810 / 22). Same form, same fit, same geometry. No holder modification required. If you are running one of these OEM blades now, the K22 drops in without changes to your toolhead setup.
What is oscillating through cutting?
An oscillating blade moves up and down at high speed as it cuts, rather than dragging. This makes it effective on thicker, denser materials where a drag blade would deflect or stall. Combined with a through-cut geometry, the K22 cuts completely through all layers of the material, including any backing. The cut piece separates fully from the sheet.
Fine grain tungsten carbide
The K22 is ground from fine grain tungsten carbide. Compared to standard carbide, fine grain holds a sharper edge longer and handles the constant impact of oscillating motion without chipping. For production environments running thick or dense materials, that means more cuts per shift and less time changing blades.
Common questions
How do I know this fits my machine?
If your machine uses the Esko BLD-SF422, Zünd Z22, Gerber MCT SE22, or Summa L25 blade, the K22 is a direct replacement. If you are not sure which blade your machine takes, contact us before ordering. We can confirm fit from your machine model and toolhead configuration.
What materials does it cut?
The K22 handles corrugated board, foamboard, folding carton, felt, leather, foam rubber, carpet, sandwich board, honeycomb, sandblasting mask, PET acoustic felt, varnish blankets, and 3M VHB. Maximum cutting depth is 0.551in (14.0mm). For thinner kiss-cut applications such as vinyl or transfer tape, a drag blade is a better fit.
What do the cutting angle and wedge angle mean?
The K22 features a 63° cutting angle and a 79° wedge angle. The 63° cutting angle helps the blade track smoothly through the material with reduced drag, while the 79° wedge angle provides the ideal 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 cut quality. If the blade is dragging rather than cutting cleanly, tearing material edges, or not releasing from the cutting surface the way it should, swap it out. Do not wait for a complete failure. A dull blade adds stress to the toolhead and leaves ragged edges that slow finishing work downstream.
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.
