High-quality claw couplings are one of the most important parts of a compressed air system. Atlas Copco couplings are forged, machined, hardened, galvanized and chromium-plated to withstand almost any abuse they might encounter. They have thinner walls than cast couplings, resulting in less resistance to air flow. Reduced airflow loss makes pneumatic tools work at optimum pressure and air flow.
The manufacturing methods allows thin walls, thus allowing a bigger hole for a given hose diameter. The hole is machined to enable perfect centering and a smooth surface. The seal has a machined seat so that it fits perfectly and does not disturb air flow.
In addition, a full portfolio of hose couplings and clamps is available.
A top-quality claw coupling has thin walls, allowing maximum air flow.
As few as six inferior, flow-choking couplings in the system can result in a power loss of 20% or more.
A 20% power loss means that at least 20% less work is done.
DKR-36 plug rock drill is light and able to drill small diameter holes in concrete and rock. For such small but powerful machines, the plug hole drill steels have been specially made. The carbon tungsten ensure a long drilling lifetime, and the wide portfolio in diameters and lengths ensures you can get the best performance of the DKR-36.
