RUKO ULTIMATECUT Conical Countersink, HSS, Ø 23 mm, DIN 355, 90°.

The RUKO ULTIMATECUT 4S tapered countersink, model Ruko-102882P, 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 achieves a perfect countersinking pattern without vibration marks, saving up to 50% of machining time and extending tool life up to three times longer compared to conventional models.

The ULTIMATECUT 4S can countersink diameters up to 40 mm, even when using hand-held screwdriving and drilling tools. Its versatile design ensures optimal performance on both pillar drills and CNC-controlled machining centers.
