SDS PLUS rotary hammers: the best models and features of the tool
Choosing a good hammer drill is not an easy task. It’s one thing - the technical specifications declared by the manufacturer, and quite another - the instrument’s compliance with them, the period of maintenance-free operation, the accuracy of work and other parameters. In this article we have collected information on SDS PLUS rotary hammers, we will tell you what features these rotary hammers have, in which case you should use this type of rotary hammers, and also consider the best models of rotary hammers with SDS Plus mounts.
Features of rotary hammers with SDS PLUS chuck
The SDS (Special Direct System) system is designed for fastening a drill shank, chisel or other equipment and is used in light and medium perforators. It allows you to fix a snap with a simple movement and replace it in a matter of seconds.
The SDS PLUS shank has a diameter of 10 mm; it is installed in the power tool holder to a depth of 40 mm. The locking balls securely fix it in the grooves. The diameter of the drill used can reach 32 mm. Drilling can be carried out in shock and shockless mode.
SDS PLUS rotary hammers are ideal for home use. Such a puncher copes well with drilling stone, concrete and other hard materials. Lightweight rotary hammers are used to drill holes from 4 to 16 mm in diameter and are rarely used as a percussion instrument since their impact force is quite small. Medium punchers are designed for drilling holes with a diameter of 16 to 25 mm and for dismantling.
In terms of chiselling, SDS PLUS rotary hammers can handle small to medium impact loads. For example, they can be used to dismantle tiles or masonry. But work on the gating should be carried out with caution, since the small diameter of the tool shank does not have significant strength and can break under strong shock loads. In addition, this can lead to premature wear of the lock balls of the SDS PLUS cartridge.
Another drawback of SDS Plus punchers is that, due to the small diameter of the shank, drills with a diameter of 18 mm or more are observed misalignment. The drill begins to "walk", which affects the usability and quality of work performed.
Next, we suggest that you familiarize yourself with the rating of SDS PLUS rotary hammers based on user reviews and ratings.
