Slitting Blades - American Cutting Edge

Slitting Blades

American Cutting Edge has the largest stock in the USA for slitter blades.  We stock all types of injector blades, 43mm “3-hole slitters” and slotted blades, The converting and slitting industry is very important to us, so we offer all these blades in a wide range of thickness, materials, coatings and edge geometries.  We are thus able to always ship these items the same day they are ordered.

A slitter blade means many different types of blades. We also supply a full range of circular slitting blades.  We stock shear cutting blades that act much like a pair of scissors.  The top blade run against the side of the bottom blade and this shearing action works well when edge quality and long life is important.  We also have all types of crush cutting blades (most are 3” in diameter) where the blade actually “crushes” through the material against an anvil blade.  This application is used on harder to cut material where edge quality is not as critical, but economy is.  Razor slitting is often used when narrow strips are required or when the application is need for there to be only a small bit of material displacement as the cut product passes by the blade.  Regardless of the slitting application, we know the business and can help!

We offer these blades in stainless and carbon but also use tungsten carbide and zirconium ceramic.  The last two types will last much, much longer, but they are more expensive and less “tough”.  However, if you have a controlled application where blade breakage does not occur and not shutting down your machine to replace blades, will save you money, these materials can be excellent choices.  We introduced the first successful solid tungsten carbide blades over 35 years ago so we know a bit about these blades, just ask!

We also stock many coated blades, using Titanium Nitride (TIN), Boron Carbide (ceramic coating) and (Titanium Carbide) TIC. TIN is much less costly, but offers a little longer life, while TIC lasts much longer, but the heat required to apply it makes it sometimes warp, a problem with thinner blades.  Often our Ceramic Coating is the best choice, as the blades will not bend during coating and it offers a very long life.  All these coatings work best in certain applications, so ask us which would be best for you!

Our focus is to make consistent quality blades where the 10,000th piece is as good as the first piece.  You don’t just need one good blade; you may need thousands of good blades! We can modify the edge geometry to make the blade cut best for your application.  If you need blades with a single bevel, a double bevel or even a compound double bevel, we can do it.

For special blades, we can also help with low cost prototype blades and then
take you to the next level, production orders.  We look forward to hearing from you!
