Challenge Replacement Blades

Our selection of Challenge Machinery replacement cutter knives are the best in the business! DiamondCut® to exceed the OEM specifications for accuracy, strength, and longevity, our replacement blades have been known to actually last up to five times as long as manufacturer-direct knives. This is possible with our unique equipment that actually uses diamond to shape and sharpen the blade. And what's better is that these premium blades are still less expensive than the manufacturer blades!

So what are you waiting for? Just select the Challenge cutter model that you have from the below list to see the blades available. Compare the specs, include blade size and any holes or other markers for accuracy, and then buy the blades online for quick shipment and delivery. Most replacement blades are available in different grades of steel, so you can choose the best option for your specific volume and material cutting needs. Standard inlay and high speed steel are the most popular, and some select blades are available available in a high carbon/high chrome option.

Don't see your Challenge cutter below? Call us at (866) 537-2244 and we can get it for you! We have various other blades in stock that are not listed online, and can also make custom blades to your exact specifications.
