What is the maximum cutting diameter of a brushless pruning shear? What types of trees can it be used for?

Brushless Pruning Shear is a highly efficient electric tool widely used in modern orchards, forestry, and gardening management. With the continuous upgrading of battery technology and motor drive technology, brushless pruning shears have made significant progress in cutting capacity and applicability. Its "maximum cutting diameter" is one of the key indicators that users pay attention to when selecting, which directly affects pruning efficiency, scope of application, and work safety.

Definition and influencing factors of maximum cutting diameter
The maximum cutting diameter refers to the maximum branch diameter that can be cut by brushless pruning shears under standard working conditions, usually expressed in "millimeter (mm)". This parameter is affected by many factors, including motor torque, blade material, blade opening angle, battery voltage output capacity, and control program settings.
Generally speaking, the mainstream brushless pruning shears on the market have a maximum cutting diameter range of 25mm to 45mm. Some high-end industrial-grade models can even reach more than 50mm, which is suitable for forestry and pruning of thick branches and fruit trees.

Common cutting diameter classification
Light model (20-25mm)
Suitable for daily pruning of twig crops such as bonsai, grapevines, tea trees, shrubs, etc. Suitable for use in gardening enthusiasts, small orchards or urban greening scenarios.
Medium model (30-35mm)
Suitable for pruning main branches and secondary branches of economic fruit trees such as apples, pears, peaches, plums, citrus, cherries, etc., especially suitable for orchard managers who need greater work intensity and continuous work.
Heavy model (40-50mm)
Suitable for fruit trees and woody plants with thick trunks or high degree of lignification such as olives, walnuts, hazelnuts, chestnuts, mulberry trees, coconuts, etc., widely used in high-load pruning environments such as forest farms, nurseries, and large farms.

Requirements for cutting capacity of different tree species
Grapevines and shrubs
These plants have thin and dense branches and are pruned frequently. It is recommended to use light brushless pruning shears with a maximum cutting diameter of 20mm~25mm, which can achieve fast, precise and low-loss pruning.
Stone fruit trees (peach, apricot, plum)
These fruit trees have many branches and medium hardness, and the branch diameter is usually between 20mm and 30mm. Using a medium-sized model with a maximum cutting diameter of 30mm to 35mm can effectively improve pruning efficiency and reduce operator fatigue.
Apple, pear, persimmon and other pome fruit trees
The branches are hard, and the main branch diameter is often up to 35mm. It is recommended to use a model with a cutting diameter between 35mm and 40mm to ensure sufficient cutting force and protect the tree from being torn.
Nuts and economic trees (chestnuts, walnuts, olives)
The trunk is thick and difficult to cut. It is necessary to choose a heavy-duty brushless pruning shear with a maximum cutting diameter of 40mm to 50mm to cope with the pruning needs of harder wood structures.
Seedlings and landscape tree pruning
In the landscaping industry, brushless pruning shears are often used for shaping and pruning, and removing dead branches. Depending on the tree species, the cutting diameter needs to cover the range of 25mm~40mm. It is recommended to choose a mid-to-high-end model with multi-speed force adjustment function.

The effect of brushless motor on cutting diameter
Compared with traditional brushed motors, brushless motors have higher efficiency, stronger torque output and longer service life. Pruning shears with brushless motors can achieve more stable torque control. Even when cutting branches close to the maximum diameter, they can still maintain linear output to avoid "knife jamming" or "machine burning".

In addition, with the intelligent chip control system, brushless pruning shears can automatically adjust the output force according to the cutting object, extend the life of the blade, and improve the cutting accuracy.
