Hole saw HW

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 ∅
