Made for the Summa Corrugated Tool
Summa designed the 500-9822 for its 500-9321 Corrugated Tool. If your Summa runs that tool, this is the knife it takes.
Asymmetric angle, DLC coating
The asymmetric 50° grind is built for burr-free cuts in corrugated board. The DLC (diamond-like carbon) coating is a thin, hard layer that reduces friction and keeps the edge sharp longer, which matters in abrasive board.
Common questions
How do I know this fits my machine?
The 500-9822 fits the Summa 500-9321 Corrugated Tool. If you are not sure which tool your Summa has, send us your machine model and we will confirm before you order.
How do I know when to replace it?
Watch the cut edge. Burrs, crushed flutes, or ragged edges on corrugated board where it used to cut clean all mean the knife is dull.
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?
