When deciding which discs are better to choose for a wall chaser for concrete, reinforced concrete and other materials, all the subtleties should be taken into account. The standard sizes of diamond wheels - 125 and 150 mm - do not always provide a sufficient immersion depth. To learn more about the features of the choice, the ability to change the discs on the wall chaser, a detailed overview of all the important points will help.

Specialized diamond blades for chasing machines are metal cutting elements, sharpened in a special way. The main classification assumes their division by purpose, as well as by the type of edge. This makes it much easier to select the appropriate options for cutting materials for specific tasks.
Concrete discs are the most common type of disc for wall chasers . They are based on durable stainless steel. A diamond coating is applied along the edge, which allows to significantly increase the strength of the cutting element.
According to the type of construction, concrete circles for a chasing cutter are divided into several varieties
Segmental . In this type of disc, the edge is divided into "petals" with through grooves between them. The slots are located on the circle radially, designed to remove excess heat, debris and dust. And also they allow to reduce the stress arising in the cutters, to reduce the linear expansion of the material. Segment discs are used when working with a wall chaser on dry material.
Whole . Discs of this type have a one-piece structure with holes along the entire radius. They are intended for cutting concrete in combination with water cooling of the surface. The holes reduce the stress on the cutting element.
Turbo segment . They have a characteristic wavy surface, divided into segments. This is the most expensive option for cutting concrete, but the discs have a long service life and high strength.
Special wheels for cutting reinforced concrete also fall into this category. They always have a segmented design and are distinguished by a large amount of diamond deposition on the surface of the cutters.
Dimensions (edit)
The size range of chaser blades is divided into 3 categories. The larger the diameter of the element, the deeper the groove will be.
Here is a classification by size
- Small . This category includes discs with a diameter of 115 mm, 125 mm, 150 and 230 mm. The maximum size is 30 cm.
- Average . Discs of this type have a diameter in the range of 350-700 mm. They are used most often in a professional instrument.
- Big ones . This category includes discs with a diameter of over 800 mm.
The maximum possible sizes of cutting elements are indicated in the instructions for the tool. It is not recommended to exceed these figures.
Which one is better to choose?
The basic recommendations for choosing a blade for a chasing cutter are quite simple. The first thing you need to pay attention to is the size of the bore . It is determined by the size of the stud installed in the tool. In most household models, this diameter is 22.2 mm, professional ones are more often equipped with a 25.4 mm option. This indicator must correspond to the marking indicated on the disc itself.
In addition, the outer diameter must be taken into account. Its range is also determined based on the instrument passport . Specific dimensions are chosen depending on the cutting depth required for the job. For example, chasing a channel for a cable or pipes, electrical wiring is performed with a 60 mm immersion into the wall. In this case, a disc for concrete should be taken with a diameter of 180 mm. Reinforced concrete works must be carried out only with special discs designed for such actions. They easily cope not only with artificial stone, but also with steel reinforcement. Regular circles will not withstand such an intense load.
And also, when choosing suitable discs for a chasing cutter, it is worth paying attention to a number of points
- Volume of work . If you don't have too much to do, it would be most reasonable to purchase consumables in the middle price range. For regular use or professional use, discs are purchased from well-known manufacturers at a price of over 1000 rubles per unit.
- Construction type . When using water cooling, segment discs are not used. Only solid options are used here. For work on dry material, segment solutions are suitable, which effectively remove the heat generated during the chasing process.
- Material type . Segment discs are used for slitting bricks, concrete, artificial or natural stone. Solid - take for making narrow and deep holes where high cutting accuracy is required. For reinforced concrete, special or turbo segment discs are better suited.
- Brand . The best chasing cutter discs come from the same brands as the tools themselves. When choosing the most compatible options, it is worth giving preference to the brand of circles from the equipment manufacturer.
- Cutting edge design . It can be with an arbitrary spraying position or in the form of a sandwich with multidirectional layers. By the method of application, the options of discs treated with a laser or electroplating are the most appreciated. Diamond solder is the least sticky.
Considering all these recommendations, you can choose a suitable disc for installation on a channeler.
It is worth considering that with parallel grooving, 2 circles are installed on the tool at once. Accordingly, when purchasing, you need to take care of the availability of a sufficient stock of consumable items.
How to change on a wall chaser?
In order to install a new disc on the wall chaser, you need to stock up on a special wrench, with which the tension of the fastening nut is adjusted. The instrument must be removed from the storage case. Next, you need to act in a specific order.
- Find on the body of the device the key responsible for unlocking.
- Insert the supplied key into it. It is important to avoid heavy pressure.
- Holding the tool by the handle, turn the wrench counterclockwise. It is necessary to control the position of the handle in order to avoid uncontrolled opening of the chaser when the internal springs loosen.
- Carefully flip open the instrument cover. Find the support flange with nut and washers inside.
- Press the button responsible for unlocking the spindle.
- Remove the washer and nut from the flange, remove the bearing element itself. Install discs on it - there should be two in total, the groove width is selected based on the desired range.
- Place the flange on the spindle. Press down the lock button. Install nuts and washers, fasten them. Complete the fixing with the key.
- Insert the key into the tool body. Close the lid. Turn the key to lock it in place.
If done correctly, the tool will be ready for use. If there is a need for a subsequent replacement of disks, it will be enough just to repeat all the operations.
