The Ruko ULTIMATECUT 4S countersink, model 102885P, is a high-precision tool designed to deliver superior performance when countersinking various materials. With its innovative four-edge design, this countersink significantly reduces axial and radial forces, resulting in smoother and more efficient operation. Thanks to its advanced technology, it allows for countersinking up to 40 mm in diameter, even with hand-held screwdriving and drilling tools.
The ULTIMATECUT 4S not only guarantees a perfect finish without vibration marks, but also provides energy and material savings of up to 50%, as well as a tool life that can be up to three times longer compared to conventional countersinks.
Its three-component handle ensures a firm grip and optimal power transmission during work, while the RUnaTEC coating further enhances its performance, especially on demanding materials such as heat-treated steel.- Number of cutting edges: 4
