Types of brush cutter blades

It is important to know about the different types of brush cutter blades and the distinctions between them. It would not only help you decide on buying one, but also educate you on what is best for your tool or requirement. There are mainly four different types of brush cutter blades – knife, chisel, smasher, and mulching.

Knife blades:

These are the most common type and the standard piece to come with maximum brush cutters. They are usually stamped or lasered from thin steel sheets and come in various shapes or designs. The blades comprise several teeth as the cutting component that have sharp, front edges and slice through vegetations.

The cutting ability of such blades increase with the number of teeth they have. They are mainly intended for cutting through softer materials and are usually very durable. Moreover, they are easy to manufacture which makes them very affordable. However, knife blade teeth tend to dull out quickly and prone to breaking off when hit by a rock or pebble.

Chisel blades:

Like knife blades, chisel blades have multiple teeth but significantly higher in number. However, there are further variations in the structure of this type. First, the teeth can be a continuous part of the disc, making it a one-piece blade, but bent offset. Second, the teeth can be chainsaw type, riveted to the main disc. And third, actual chainsaw chains fitted between two discs. These blades function mainly by shaving off or chiseling vegetations, not by slicing them. They cut best horizontally and are particularly good for woody substance (up to 60 mm thick).

Unlike knife blades, the cutting ability for chisel blades does not necessarily increase with the teeth number. A higher teeth number is not an issue in case of cutting soft, thin saplings. But for cutting thicker saplings or twigs, a higher teeth number means an increased loss of power. So for chisel blades, less teeth number is more efficient. Being more complex in structure, such blades usually cost more than knife blades. Previously, steel was a common choice of metal for manufacturing these blades. But over the years, tungsten carbide tips have taken over the design, which brought the cost down substantially.

Smasher blades:

These are not blades really; they have pivoting metal parts that smash through the foliate. They lack sharp edges and depend primarily on the weight of the blades that remove brush or weeds using centripetal force. Since slicing is not the forte of such blades, smasher blades are good for soft material like grass or water weeds only.

Multiple metal parts mean that these blades cost more and consume a lot of power to maintain the rotational speed. But one advantage they have is the nonessential maintenance, i.e. no sharpening of teeth or edges. Plus, this blade is good for mulching, which takes us to the next and last type.

Mulching blades:

Also known as 3-in-1 blades, mulching blades are used for mulching, bagging, and discharging. They have higher cutting edge comparatively and include curves, along with two cutting planes along their edges. This enables the blades sweep the grass into the deck and cut them several times into tiny pieces, that fall back onto your lawn. They work best with large brush cutters, as they require more power, and are fit for regularly mowed lawn. This is because overgrown grass tend to clog under the deck, making mulching blades not suitable for tall grass or woody weeds.

Things to consider when buying a brush cutter blade

If you’re a neophyte in this world of tools and accessories, then this section is a must-read. The following are some points which determine the quality of a blade. Scrutinize these factors and you’ll certainly manage to get yourself a good piece.


The metal quality greatly influences the performance of a blade. High quality steel certainly means a high price, but it also means longer durability. It would make absolutely no sense to buy a cheap and low quality blade as you’d have to replace it with another one very soon, ultimately spending more. Therefore, it is better to look for blades made of proper metal that can withstand the constant cutting and scuffing.


Generally, the number of teeth indicate the strength of the standard blade attachment. Blades can have 0 to as much as 120 teeth, thus having low to high strength.

For short grass in small households, blades with no teeth or 20 teeth should work, but they are the least powerful of all. Medium strength blades have teeth above 20 and up to 40, that are suitable for moderate sized yards with small trees or soft grass. Lastly, blades with over 40 teeth are the strongest ones that can easily tackle heavy workloads of clearing dense brush.


Like teeth number, a high diameter typically means more power and efficacy. The commonly seen diameters are 8, 9 and10 inches. The bigger the blade, the more force it delivers via the higher circumference, thus performing better and faster.

But do keep in mind that your machine has to have adequate power to rotate the respective size. Bigger blades are usually compatible with gas powered or corded electric brush cutters only. If the blade is too large and your machine is underpowered, it might recoil or not spin fast enough, giving you poor results.

Arbor hole size:

The arbor hole is the center through which a blade is attached to a machine. Tools have their individual hole size which must match with the blade in question. It is important that the arbor hole size is compatible with the machine for the blade to work properly. A mismatch would not only lower the competence of the blade but could also cause the blade to fall out accidentally.

Type of blade:

As explained in the previous section, there are mainly four different types of blades that specialize in different tasks. Depending on your requirement, you can either buy the type you need or have all the types in your collection to deal with anything and everything.

Parting thoughts

In conclusion, we recommend having a complete assortment of blades if possible. Since a certain type of blade is apt for dealing with one kind of vegetation or task only, it would be unwise to depend on the most common type to carry out everything. Having a set of blades would be convenient enough for you to clear out all different types of brush or foliage, thus accomplishing multiple chores.

Lastly, now that you know almost everything about brush cutter blades, you should understand that they can be as dangerous as they can be useful. Therefore, try to maintain the following safety tips:

  • Always work during daytime.
  • Wear safety clothing and gear at all times – long trousers, googles, boots, etc.
  • Clear the area from clutter or obstacles to avoid accidents.
  • Take breaks in between working to avoid losing concentration or fatigue.
