Carbide Snow Plow Cutting Edges – An Intro Guide

Carbide snow plow cutting edges are a widely used type of snow plow blade. 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 has experts in all aspects of ground engagement edges, blades, and tools. We are doing this educational introduction series to share some of our knowledge with operators so that they can be more efficient and reduce their overhead costs.

To begin, it is important to give a brief overview of this particular snow plow cutting edge style. Carbide snow plow edges are used on the front, underbody, and wing of a snow plow. Carbide snow plow blades look very similar to traditional steel edges; however, they have a carbide insert brazed into the thickness of the steel face along the bottom of the blade. This carbide insert has much better wear resistance properties than a cutting edge made of just steel.  This gives the operator the following benefits:

  1. Longer Wear Life – on average carbide cutting edges have 3-5x more wear lifespan than heat-treated steel edges, and up to 20x more when compared to Carbon Steel
  2. Even Wear – carbide snow plow cutting edges will wear evenly across the face of the blade, which can help reduce the “crowning” effect that many operators experience with steel edges.
  3. Saves Time – Because the blades last longer and wear more evenly, operators can spend less time changing blades and more time out on the roads pushing snow.

Types of Carbide Snow Plow Edges

There are a wide variety of carbide edge styles for snow plows. The standard is a flat, 3/4″ thick by 6″ tall blade with a single carbide insert. These edges are great for front mounts, underbodies and wing plows. It is important to note that specific mounting applications have specific additional edge qualities. Specifically, an underbody blade should have a top bevel, whereas front mount and wing blades are unbeveled square edges.

Another type of Carbide snow plow edge is a serrated edge. These blade types are designed for a more aggressive cut that can easily break through hard compacted snow and ice. The blades are easy to identify (as you can see in the picture below) because they have a carbide square welded to the front that look like teeth.

Hybrid Edges

Finally, there are some carbide snow plow edges that are more of a hybrid. These blades can consist of steel and/or rubber in addition to the carbide segments. In these cases, the carbide and steel segments are completely encased in a rubber shell. The most common model for these hybrid blades consist of a steel mounting blade, rubberized carbide segment (pictured below), and a steel cover plate. The mounting plate and cover plate offer stability for the rubber segment.

This setup is beneficial for operators because it helps give a better clean sweep on snow. You can almost think of it as a squeegee effect on the road surface. Plus, the rubber embedded metal snow plow blades offer greater flexibility to contour to changing road surfaces and the rubber also drastically decreases vibration on the machine for a better operating environment.

Carbide snow plow edges are a great way to increase wear life and decrease the time and effort that changing blades creates. The extended wear life of carbide does come at a higher price than a steel edge; but when ran properly the longer wear life and cost savings will be a financial advantage in the long run.

Ideal uses of carbide snow plow cutting edges:

  • Highway & interstate roads
  • Municipal/city streets
  • Private/commercial parking lots
  • Residential roads

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.
