DDX dry drill bits

Features

• Thanks to the innovative bond system of TGD®+ technology, efficiency is maximised and the profile is specifically controlled
• Excellent and fast cutting performance thanks to the high thermal load capacity
• Higher running smoothness due to the degree of occupancy as with wet drilling
• Core stopper in the range Ø 52 to 152 mm
• Low contact force required & therefore relatively low heat generation

Applications

• For 3 kW drill motors with soft impact function with stand-guided setup
• Drilling reinforced concrete that could previously only be drilled with wet drill bits
• Technically, a hybrid application (dry & wet) is possible if low-wear materials (e.g. highly compressed precast concrete parts) have to be drilled in the wet process

Technologies

• 

  TGD®+ technology is characterized by an innovative bonding system that enables different degrees of hardness and smooth transitions within the diamond segment. In combination with different diamond grain qualities, this ensures improved running smoothness and balanced load distribution. This targeted profile control minimizes power losses and maximizes efficiency, which reinforces the self-sharpening effect of the segment.
