Plus Quadro-L hammer drill bit

Significant improvement of service life in rebars and concrete

• Due to the innovative and symmetrical head geometry with four cutting edges, the solid carbide head (dia. 5-20 mm) and the one-piece carbide element and Peak design (dia. 22-32 mm)


• The rebar margins on the cutting edges prevent the drill bit from jamming or running off centre when hitting e.g. reinforcements

Noticeably quicker drilling

The enhanced tip geometry with power edges, additional dust grooves and curved cutting edges (dia. 5-20 mm) ensure fast drilling progress and transports drill cuttings to the conveyor helix

New multi-zone conveyor helix with optimised diameter for noticeably increased breakage resistance, improved drilling speed and optimum removal of drill cuttings

• Alternating wide and narrow spiral flutes in Speed and Heavy Duty designs and optimised spiral core strength, as well as wide flutes and thicker core in the head area for dia. 5-20 mm


• Spiral with reinforced core, reduced weight and significant increase in spiral volume for dia. 22-32 mm

Precise tapping

The special self-centring tip with homogeneous and smooth transitions enables precise drilling

Convex shank and transition zone

The ball-shaped end of the shank and the transition zone (smooth transition from spiral to shank from dia. 18 mm) ensure a better targeted and therefore more effective transfer of impact energy to the drill tip, thus ensuring faster drilling progress

Wear indicators on the drill head

Indicators for assessing the dimensional accuracy of anchor holes
