Selection Tips
When a user needs to purchase a universal diamond blade, there are many factors to consider.
Manufacturing material. The segment disc is used for processing dry concrete, which becomes the root cause of the rapid wear of the packing. That is why experts advise to buy nozzles with the maximum thickness if it is new concrete, and of moderate thickness if it is old.
- Most users are trying to save money, but it's not always worth it. If you plan to solve everyday problems with the help of the tool, then the disc can also be purchased at a reduced price, but with the appropriate quality, since it will not be required to solve problems of increased complexity. The main thing is not to use it without stopping and avoid overloading, then the product may well cut concrete or reinforced concrete with an average degree of reinforcement. Professional circles are a completely different category that cannot be skimped on. Their inflated cost is due to their reliability and durability.
- The last thing that the user needs to take into account is the depth of cut, since the larger it is, the larger the diameter of the nozzle should be. In this case, most people forget about the capabilities of the tool used, since it should not make a large number of revolutions, leading to premature wear of the nozzle. On the contrary, if a disc of a small diameter is put on a grinder with a minimum number of revolutions, then it will quickly heat up.
Models and their characteristics
Diamond grinding bowls can be either 125 mm or 230 mm in diameter. In professional circles, they are also called "turtles". Such a disc for concrete processing is supplied on sale with a special spraying, all models differ in shape and are designed to work in special conditions.
- Segments in one row. Such a disk weighs a little, but demonstrates great performance. Of the shortcomings, the complexity of the work can be noted, since in order to hold such a nozzle, it will take a lot of effort from the user.
- Segments arranged in two rows. It is used for roughing, as it quickly and efficiently removes any irregularities not only from a concrete surface, but also from a stone one. With it, you will additionally need to use a fine finishing nozzle.
- Product of the "Square" type. Necessary for rough surface treatment, chipping effect can be observed, thanks to which the desired result can be quickly achieved. Such a nozzle wears out for a long time, after which a roughness is observed on the surface.
- Typhoon model. Essential for stripping off super-dense material. It is characterized by high strength and long service life. The shape was specially thought out in such a way that the spent particles are quickly removed to the side and do not interfere.
- Segmented Turbo. Has a solid diamond surface, thanks to which the grinding is carried out accurately. Such a disk is used when special care is required. Most often they are used to create marble and granite monuments, since you can easily process corners and create smooth lines.
- Boomerang nozzle. Fine finishing product with fine diamond inclusions. It treats the surface gently, is highly resistant during work.
How to use?
There are a few key points to keep in mind when using angle grinders, especially if a diamond tip is used.
- Before installing the cutting disc, you will need to inspect it for integrity, since it is forbidden to use circles with a defect. This also applies to the expiration date, which few amateurs know about.
- The sharpening of the tool should be carried out exclusively with a specially designed nozzle and no other disc, since its edge is not designed for such a load and will simply fly apart during operation.
- It is impossible to put on the tool a cutting or grinding disc of the wrong diameter, as well as to use them for other purposes or in the processing of unsuitable material. Installing a nozzle with a larger diameter will require removing the protective cover, and this is strictly prohibited for safety reasons.
