Ruko 31mm 90° Runa TEC Coated HSS Ultimate Cut Countersink

Ultimatecut taper and deburring countersinker is a high performance tool which stands for best performance up to 30% time savings, twice as many countersinks as standard tools and excellent, smooth countersinking results in almost all materials. The specially developed countersink from RUKO achieves this through its unique cutting edge geometry, with the specially developed variably running relief grinding, transition radius and the extra-wide chip flute.
