STEPPED TWIST DRILL BITS - Würth

1 MWF - 09/11 - 06798 - STEPPED TWIST DRILL BITSE normously versatile and extremely fast STEPPED TWIST DRILL bits with particularly long service livesExtremely precise initial drillingthanks to self-centering drilling tip Up to 30% fasterin comparison with the competition thanks to the optimally harmonized cutting edge geometryUp to double the service lifein comparison with the competition thanks to a reduction in the wear on the drilling tip, main cutting edges and on the radial and axial relief grind No slipping through in the DRILL chuckthanks to 3-face shank and 1/4 bit holder Precision workthanks to laser-inscribed diameter in both spiral groovesHardly any reworking necessarythanks to precise and circular DRILL holesDrilling step dia.
