RUKO KES-DIN335-HSS-TiN-90°-12,4mm svasatore conico

Deburring and chamfering holes in metal and plastic can be time-consuming and leave rough edges. The RUKO KES-DIN335-HSS-TiN-90°-12.4mm countersink bit solves this by producing clean, precise 90° chamfers in a single pass. Its 3-flute design and TiN coating reduce friction and heat, extending tool life and improving surface finish.
