6-part cone and deburring cutter set ULTIMATECUT DIN 335 Form C 90° HSS - 6-part cone and deburring tool set ULTIMATECUT DIN 335 Form C 90°Ø 6.3 - 8.3 - 10.4 - 12.4 - 16.5 - 20.5 mm(Ø 16.5 mm = shaft-Ø 10.0 mm)The 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: High-performance high-speed working steel for drilling in well-machined materials with a strength of up to 900 N/mm².
