Snow Plow Cutting Edges – An Introduction to Carbide

Carbide snow plow cutting edges are widely used today.  They are a natural progression from standard steel snow plow edges which were discussed in the first post of this series: Snow Plow Cutting Edges – An Introduction to Steel. DMC Wear Parts carries all the styles of carbide edges; and we are happy to give a brief overview of this particular blade style.  Carbide snow plow edges are used on the front, underbody, and wing of the snow plow. Carbide snow plow blades look much the same as steel edges; however they have a carbide insert brazed into the thickness of the steel edge along the bottom of the blade.  The carbide insert has much better wear properties than steel.  This gives the benefits of:

  1. Longer Wear Life – on average 3-5x more wear than heat treated steel edges, up to 20x more compared to Carbon Steel
  2. Even Wear – blades will wear evenly; reducing “crowning” effect steel edges have.
  3. Less Time Spent Changing Blades

Types of Carbide Plow Edges

There are a wide variety of carbide edges for snow plows.  The standard is a flat, 3/4″ thick by 6″ tall blade with a single carbide insert.  These are great for front mounts, underbodies and wings.  Please not that an underbody blade should have a top bevel; whereas front mount and wing blades are square.

Carbide blades also can be serrated; for a more aggressive cut on snow and ice. The blades pictured have a carbide square welded to the front of each tooth.

Carbide blades can also be a hybrid consisting of steel, rubber, and carbide segments. The carbide and steel segments are completely embedded by rubber.  These blades offer a flexibility to contour to changing road surfaces, and also drastically decrease vibration for a better operating environment.  They typically consist of a steel mounting blade, rubberized carbide segment (pictured), and a steel cover plate. The mounting plate and cover plate offer stability for the rubber segment. This setup will give a better clean sweep on snow, think of a squeegee effect.

Carbide blades are a great way to increase wear life and decrease the time and effort that changing blades creates.  The wear life does come at a higher price than a steel edge; but when ran properly the wear life and cost savings will be an advantage financially.  Please feel free to reach out to DMC Wear Parts to discuss more about carbide snow plow edges and get a quote.  There are many different styles to choose from, and as always we want to provide Parts for Progress.  Call (605) 840-8082 or email:

Snow Plow Cutting Edges – An Introduction to Steel


Snow plow cutting edges come in many different sizes and varieties; sorting through them to find out what is best for your operation can be difficult.  This series of posts will serve as a beginner’s reference to better understand the different choices of snow plow blades; so you can choose the best blade to bring progress. First we take a look at steel snow plow blades. 

Steel snow plow cutting edges are widely used today.  Mainly because they were the first design and they are the cheapest option. Steel edges are used on the front, underbody, and wing of the snow plow. Steel snow plow cutting edges can be carbon steel (sometimes called butter blades) or heat treated steel.  Heat treated will offer considerably better wear life compared to carbon and is more than worth the extra cost per foot.  

Steel snow plow blades range from 3’ to 12’ pieces. Shorter lengths are typically preferred to make changing easier.  The blade itself; is flat, non curved, with a  square edge. However, underbody blades do require a beveled top edge, similar to a motor grader cutting edge.  Typical dimensions for a steel snow plow blade are 3/4” x 6” for front mount, 3/4 x 8” for wing, and 7/8×5” for an underbody with a hole pattern of 3”-3”-12”. While steel snow plow blades are the lowest cost per foot they also provide the lowest wear life.  When using steel edges in high usage operations; all costs associated with changing cutting edges should be greatly considered.  In our opinion steel snow plow blades are a cost effective plow option for low usage situations.  Better alternatives for heavy usage situations will be discussed in future posts.
