8x100MM GUIDE DRILL FOR SDS PLUS HOLE SAW RT-HCB-PD8

Widia plates soldered at high temperature provide high resistance to chipping and increase service life. The oblique arrangement of the widia plates ensures greater drilling efficiency in hard concrete. The M16 internal thread, cold forged, creates a strong connection to the adapter core and protects against breakage. A pilot drill with a diameter of 8 mm and a length of 100 mm allows precise drilling start in the selected place. The side locking screw prevents the pilot drill from moving within the adapter. The SDS plus holder fits all hammer drills of this class on the market.
