Uniform CNC grinding with specially matched, cutting pressure-reducing cutting shape
Precise, clean cut with low tolerances
Stepped, optimised centre drill (GS-protected system)
- Eliminates the need for laborious centre punching, as the drill can be centred without drifting off course
- Reduced drilling force and over 50% reduction in drilling time coupled with lower power consumption (depending on the hand-held drill used)
Precise, optimally embedded seating of the carbide teeth via a unique, fully automatic soldering process
High cutting performance and long service life
Cut depth limiter
Prevents work accidents and protects the tool and machine from damage
Ejection spring
- Protects shock-sensitive carbide teeth after pre-drilling when the drill bit enters the medium
- Ejects the drilled-out piece ("drill core") automatically once drilling is complete
Separate hardened shaft for ∅ 32 mm upwards
Compensation for the increasing torsion and torques associated with increasing ∅
- The cylinder saw must be seated securely in the drill chuck
- Avoid tilting of the cylinder saw
- Appropriate protective clothing such as safety glasses, gloves etc. must be worn during work
For use with upright and hand-held drills in tool steels, construction steels, non-ferrous metals, non-rusting metals (e.g. A2 and A4), asbestos, fibreglass and plastics, PVC, zinc, plaster boards, light building boards and thin-walled wood and laminated panels, e.g. furniture rear panels.
Max. cutting depth in steel = 4 mm, in stainless steel = 2 mm. Ensure that the saw is sufficiently cooled/well lubricated. Recommended speeds must be observed. Do not make oscillating movements with hand-guided drills, as this movement places uneven loads on the carbide teeth, which could cause them to break. For saws from 30 mm diameter, use an upright drill.
