The screw-hole punches by Ruko are capable of cutting holes through thin materials rapidly, simply and neatly. It executes this in a few simple applications, without requiring burrs. The three-point cut provides enhanced contact.
Therefore minimal deformation of the punched parts, which avoids the damage to the draw-in bolt. The ball bearing between draw-in bolt and die plate makes handling simple and fast, which reduces the force needed by approximately 67%.
Before the screw-hole punch is utilized, the draw-in bolt should always be lubricated with Ruko's cutting spray or cutting paste. The metric draw-in bolts of Ruko screw hole punches are always in good quality grade, and are therefore made for challenging loads.
