Centrotec shank allowing the user to ditch the keyless chuck
Bits are centered automatically and cannot slip unlike traditional smooth-shank masonry bits
Set in full range of sizes from 4-10mm
Festoon's masonry bits are the only ones that feature a Centrotec shank allowing the user to ditch the keyless chuck for a faster change over between drilling and driving. In addition, thanks to the Centrotec shank, the bits are centered automatically and cannot slip unlike traditional smooth-shank masonry bits. Set in full range of sizes from 4-10mm. Masonry drill bits are best used with the PDC style hammer drill in both hammer as well as drill mode for bricks, blocks, and tile.
