6-part cone and deburring cutter set ULTIMATECUT DIN 335 Form C 90° HSS Co 5 RUnaTEC - 6-part cone and deburring cutter set ULTIMATECUT DIN 335 Form C 90° HSS Co 5 RUnaTECà 6.3 - 10.4 - 16.5 - 25.0 - 25.0 mmThe ULTIMATECUT countersink is a high-performance tool that stands for best performance: Up to 30% time savings, twice as many reductions as with standard sinks and an optimal smooth lowering result in almost all materials. The RUKO countersink achieves this by its unique cutting geometry, with the specially developed variable relief, Transition radii and the extra wide clamping groove.- achieves the best performance in almost all materials and applications - much less feed force required - up to 60% higher service life - up to 30% faster lowering - extremely smooth running - optimal vertical image - ideal chip removal. HSS Co 5: High-performance high-speed working steel with 5% cobalt content. High toughness and heat resistance, for drilling in hard-to-work materials with a strength of up to 1100 N/mm². RUKO Nano Technology - extremely high wear resistance and hot hardness - suitable for normal and high-performance machining - no material welding - optimal, smooth surface - extremely high nano-hardnessThis text is machine translated.
