6-piece cone and deburring countersink set ULTIMATECUT DIN 335 Form C 90° HSS Co 5 RUnaTEC - 6-piece cone and deburring countersink set ULTIMATECUT DIN 335 Form C 90° HSS Co 5 RUnaTECØ 6.3 - 8.3 - 10.4 - 12,4 16.5 - 20.5 mm. The ULTIMATECUT countersink is a high-performance tool that stands for best performance: up to 30% time saving, twice as many reductions as with standard countersink cores and an optimal smooth countersink result and that in almost all materials The countersink from RUKO achieves this thanks to its unique cutting edge geometry, with the specially developed variable background, transition radii and the extra wide flute - achieves best performance in almost all materials and applications - significantly less feed force required - up to 60% longer service life - up to 30% faster countersinking - extremely smooth running - optimal countersinking - ideal chip removal HSS Co 5: high-performance high-speed steel with 5% cobalt content High toughness and heat resistance, for drilling into hard-to-work materials with a strength of up to 1100 N/mm²
